How to Find Prime Numbers in an Array in C#?

Bijay — Mon, 18 Dec 2023 08:00:00 +0000

Do you want to find prime numbers in a C# array? In this C# tutorial, I will explain how to find prime numbers in an array in C#.

To find prime numbers in an array in C#, iterate through the array and check each number with a function that determines if it’s prime. This function should return false for numbers less than 2 and then check divisibility up to the square root of the number, returning true only for numbers that are not divisible by any other number except 1 and themselves.

Find Prime Numbers in an Array in C#

Now, let us write a program to find prime numbers in an array in C#.

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. The first few prime numbers are 2, 3, 5, 7, 11, and so on.

To check if a number is prime, we need to test if it is not divisible by any number less than itself and greater than 1. The most efficient way to do this is to check divisibility up to the square root of the number.

using System;
using System.Collections.Generic;

class PrimeFinder
{
    static void Main()
    {
        int[] array = {2, 3, 4, 5, 6, 7, 11, 13, 17, 18, 19, 23, 29};
        List primes = FindPrimesInArray(array);

        Console.WriteLine("Prime numbers in the array are:");
        foreach (int prime in primes)
        {
            Console.WriteLine(prime);
        }
    }

    static List FindPrimesInArray(int[] arr)
    {
        List primeList = new List();
        foreach (int num in arr)
        {
            if (IsPrime(num))
            {
                primeList.Add(num);
            }
        }
        return primeList;
    }

    static bool IsPrime(int num)
    {
        if (num <= 1) return false;
        if (num <= 3) return true;

        if (num % 2 == 0 || num % 3 == 0) return false;

        for (int i = 5; i * i <= num; i += 6)
        {
            if (num % i == 0 || num % (i + 2) == 0)
                return false;
        }
        return true;
    }
}

Main Method: We define an array of integers and call FindPrimesInArray to filter out the primes.
FindPrimesInArray Method: This method iterates through the array and uses IsPrime to check if each number is prime.
IsPrime Method: It efficiently checks if a number is prime. We handle edge cases for numbers less than 4 and then check divisibility starting from 5, incrementing by 6 each time (since any prime number greater than 3 can be written in the form of 6k±1).

Once you run the code using a console application in C#, you can see the output in the below screenshot.

Conclusion

Finding prime numbers in an array using C# is a great way to understand basic programming concepts and number theory. In this C# tutorial, I have explained how to find prime numbers in an array in C# using the above simple program.

How to create an array in asp.net using c#.net?

Bijay — Thu, 17 Aug 2023 16:36:23 +0000

Arrays are fundamental data structures in C#.Net used to store multiple items of the same type. In this tutorial, we’ll focus exclusively on different ways to create an array in asp.net using c#.net.

Create an array in asp.net using c#.net

Let us now check, how to create different types of arrays in C#.Net. I am doing all the examples using an asp.net web form application and using C# as the language.

Create a One-dimensional Array in C#.Net

Follow the below steps to create a one-dimensional array in asp.net using C#.Net.

Declare and Initialize Simultaneously

To declare an array and initialize it at the same time in C#.Net follow the below syntax:

int[] numbers = { 1, 2, 3, 4, 5 };

Declare First, Then Initialize

We can also create a one-dimensional array by declaring first and then initializing it.

First, declare the array:

int[] numbers;

Then initialize it by specifying the size:

numbers = new int[5];

Or by specifying the values:

numbers = new int[] { 1, 2, 3, 4, 5 };

Create Multidimensional Arrays in C#.Net

Now, I will show you how to create a multidimensional array in C.Net.

Rectangular Arrays

A C#.net rectangular array has multiple dimensions.

Declare and Initialize:

int[,] matrix = new int[2, 3] { { 1, 2, 3 }, { 4, 5, 6 } };

Create Jagged Arrays in C#.Net

Now, let us see, how to create a jagged array in C#.Net.

A jagged array is an array of arrays. Each sub-array can have a different length.

Declare and Initialize

int[][] jaggedArray = new int[3][];
jaggedArray[0] = new int[] { 1 };
jaggedArray[1] = new int[] { 2, 3 };
jaggedArray[2] = new int[] { 4, 5, 6 };

Create an array using Array Class Methods

The Array class in C# offers methods to create and manipulate arrays.

Array.CreateInstance allows you to create an array dynamically:

Array dynamicArray = Array.CreateInstance(typeof(int), 5);

This creates an integer array of size 5.

Create an array with default values in C#.Net

In C#, when an array is constructed without values, it’s initialized with default values. This is helpful in ASP.NET scenarios where placeholder values are needed.

int[] defaultValuesArray = new int[5];
string[] defaultStrings = new string[3];
bool[] defaultBools = new bool[3];

Conclusion

Arrays in C#.Net are a pillar of ASP.NET development, allowing for versatile data storage and manipulation. With this guide, ASP.NET developers now have a robust understanding of creating arrays in C#.Net.

ASP.NET Control Naming Conventions

Bijay — Wed, 10 May 2023 12:39:50 +0000

Naming conventions are a crucial part of development best practices. Adopting appropriate naming conventions can improve code readability, maintenance, and understanding. In this tutorial, we will focus on ASP.NET Control Naming Conventions. The naming conventions can be used for all the ASP.NET Web Forms controls.

ASP.NET Control Naming Conventions

One of the most common conventions in ASP.NET control naming is the use of prefixes. A prefix is a short identifier added to the start of the name of the control. This prefix usually denotes the type of control.

Here are some common prefixes used for ASP.NET controls with examples:

Control	Prefix	Example
Button	btn	`btnSubmit`
Label	lbl	`lblUsername`
TextBox	txt	`txtEmail`
DropDownList	ddl	`ddlCountry`
ListBox	lst	`lstOptions`
DataGrid	dg	`dgCustomerData`
GridView	gv	`gvOrderDetails`
DetailsView	dv	`dvEmployee`
FormView	fv	`fvRegistration`
Repeater	rpt	`rptProductList`
DataList	dl	`dlImages`
CheckBox	chk	`chkRememberMe`
RadioButton	rdo	`rdoGender`
Calendar	cal	`calBirthDate`
ImageButton	imgbtn	`imgbtnProfilePic`
HyperLink	hlnk	`hlnkHomepage`
Image	img	`imgLogo`
Panel	pnl	`pnlSidebar`
PlaceHolder	ph	`phContent`
Literal	lit	`litWelcomeMessage`
Table	tbl	`tblScores`
TableRow	tr	`trHeader`
TableCell	tc	`tcName`

Naming Convention Rules for Asp.Net Controls

When naming your controls, you should adhere to some rules that will make your code cleaner and more understandable.

1. Use Camel Case

Camel case starts with a lowercase letter and the first letter of each subsequent concatenated word is capitalized. For example: btnSubmit.

2. Use Meaningful Names

The name of the control should reflect its purpose. For example, a button used to submit a form could be named btnSubmit.

3. Avoid Using Reserved Words

Avoid using language-specific reserved words in your control names. This can lead to confusion and potential runtime errors.

4. Consistency

Ensure that you are consistent in your naming throughout your application. Consistency makes your code easier to read and understand.

Examples

Following the above rules and using the standard control prefixes, here are some examples of control names:

Button used for submitting a form: btnSubmit
Text box to enter a username: txtUsername
Drop down list for selecting a country: ddlCountry
Label for displaying error messages: lblError
Image button for a profile picture: imgbtnProfilePic

ASP.NET Control Naming Conventions

Conclusion

Adopting the right naming conventions for your ASP.NET controls can greatly improve your code quality. It enhances readability, makes maintenance easier, and overall, leads to more efficient development. Remember to use the standard control prefixes, meaningful names, camel case, and avoid using reserved words, and most importantly, be consistent in your naming throughout your application.

How to create a SOAP API request with Username Token in .Net

Bijay — Mon, 24 Apr 2023 08:51:27 +0000

This c#.net tutorial explains, how to create a SOAP API request with user name token in .Net while connecting to a web service.

Create a SOAP API request with Username Token in .Net

Suppose I have a Web service URL from which I want to retrieve the data from outside organizations.

https://15.32.54.09:80/enjoySharePoint_HTTPRouter/enjoySharePointWebservice

Here I am using SOAP UI to call the secure web service using WCF. The SOAP header I need to generate to do this should contain a username, password, and created mob…

Here is an example of a soap UI header that I use to hit the same service.

create a soap header request

How to get the same information using C # code

Step 1: Open the Visual Studio – > Create a new console application

create a SOAP API request with Username Token

Step 2: Go to the references and add a service reference as per the below screenshot.

create a soap header request

Step 3: Add the above web service in your service reference and click on Go – > Change the namespace name to any custom name -> Click on OK after getting “GetUserInfo” function over here.

how to create a SOAP API request with Username Token

Step 4: Next, copy and paste the below code which we can used to get the service output

 [WebMethod]
        public string GetUserInfo()
        {
            Soap.UserDTO dto = new Soap.UserDTO();

            try
            {
                Soap.UserBeanSEIClient client = new Soap.UserBeanSEIClient();
                client.ClientCredentials.UserName.UserName = "rswain";
                client.ClientCredentials.UserName.Password = "password@123";
                ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback((sender, certificate, chain, sslPolicyErrors) => true);
                ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls;
                PasswordDigestBehavior behavior = new PasswordDigestBehavior("rswain", "password@123");
                client.Endpoint.Behaviors.Add(behavior);
                dto = client.getUserInfo("8873493980", "37232732", "kswain");
                var tem = dto;              
            }
            catch (Exception ex)
            {
                throw ex;
            }

            return dto.cpyEngName;
        }

Note: Sometimes we will get certificate issues while connecting to outside service. So here we will call a method called PasswordDigestBehavior to generate the certificate automatically.

Step 6: Next create one more class called PasswordDigestBehavior and copy and paste the below code.

PasswordDigestBehavior.cs

using Microsoft.Web.Services3.Security.Tokens;
using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel.Channels;
using System.ServiceModel.Description;
using System.ServiceModel.Dispatcher;
using System.Web;
using System.Xml;

namespace COTCWS
{
    partial class PasswordDigestBehavior : IEndpointBehavior
    {


        public string Username { get; set; }
        public string Password { get; set; }


        public PasswordDigestBehavior(string username, string password)
        {
            this.Username = username;
            this.Password = password;
        }


        void IEndpointBehavior.AddBindingParameters(ServiceEndpoint endpoint, System.ServiceModel.Channels.BindingParameterCollection bindingParameters)
        {
            return;// throw new NotImplementedException();
        }


        void IEndpointBehavior.ApplyClientBehavior(ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.ClientRuntime clientRuntime)
        {
            clientRuntime.MessageInspectors.Add(new PasswordDigestMessageInspector(this.Username, this.Password));

        }

        void IEndpointBehavior.ApplyDispatchBehavior(ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.EndpointDispatcher endpointDispatcher)
        {
            return;// throw new NotImplementedException();
        }

        void IEndpointBehavior.Validate(ServiceEndpoint endpoint)
        {
            return;// throw new NotImplementedException();
        }
    }


    partial class PasswordDigestMessageInspector : IClientMessageInspector
    {
        public string Username { get; set; }
        public string Password { get; set; }


        public PasswordDigestMessageInspector(string username, string password)
        {
            this.Username = username;
            this.Password = password;
        }


        void IClientMessageInspector.AfterReceiveReply(ref System.ServiceModel.Channels.Message reply, object correlationState)
        {
            return;// throw new NotImplementedException();
        }


        object IClientMessageInspector.BeforeSendRequest(ref System.ServiceModel.Channels.Message request, System.ServiceModel.IClientChannel channel)
        {
            // Use the WSE 3.0 security token class
            UsernameToken token = new UsernameToken(this.Username, this.Password, PasswordOption.SendPlainText);

            // Serialize the token to XML
            XmlElement securityToken = token.GetXml(new XmlDocument());

            //
            MessageHeader securityHeader = MessageHeader.CreateHeader("Security", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd", securityToken, false);
            request.Headers.Add(securityHeader);

            MessageBuffer buffer = request.CreateBufferedCopy(Int32.MaxValue);
            request = buffer.CreateMessage();
            try
            {
                System.IO.File.WriteAllText(@"c:\temp\testthord\" + DateTime.Now.ToString("MMddyyyyhhmmssfff") + ".xml", request.ToString());
            }
            catch { }

            // complete
            return Convert.DBNull;

            //throw new NotImplementedException();
        }
    }
}

Step 7: Next build the code and debug. Now you can get the output that is the same as your SOAP UI output.

Generate One Time Password (OTP) in Asp.Net using C#.Net (generate OTP in c#)

Bijay — Mon, 24 Apr 2023 08:43:21 +0000

Are you trying to generate otp in c# or looking for an otp.net c# example? In this asp.net tutorial, I will explain with an example, how to generate Unique Random OTP i.e. One Time Password in Asp.Net using C#.Net. We will see a c# otp generator.

generate otp in c#

One Time Passwords are widely used by banks and other firms to validate the Mobile Numbers of their users. OTPs can be Alphanumeric or Numeric and generally have a length between 5-10 characters. We can easily do otp generation and verification in c#.

My application is basically a login screen that uses username and password. Next, it will validate with the server to check a valid user or not. Once it validates with success result, next it will generate an OTP which will send to your register mobile no. The OTP last 5 minutes, after this time, it will expire and the user will need to generate a new one.

Now I am going to explain to make easier your comprehension. First I start with a screenshot of my application. So here is the otp generation and verification in c# or c# otp generator example.

Step 1: Open your Visual Studio next create a new solution.

generate otp asp.net

Step 2: First I am going to create a simple login screen which will valid a registered user or not in my application.

generate otp asp.net using c#.net

Step 3: In this step, it will validate the credential if it will success then it will redirect to OTP page where you can see your registered mobile no which can help you to send an OTP.

otp generator c#

Step 4: Next it will generate an OTP and same time OTP will send to your registered mobile no and the validity is only for 5 minutes after that it does not work.

otp generation and verification in c#

Step 4: If you will enter the correct OTP, then you can able to see the next page otherwise you will receive an alert ( Invalid OTP ).

Note: One point should be noted. Here I am using cookies to save the user credential because, If the same user wants to log in this application in the second time in the same day with the same browser then it won’t ask for OTP as this user has already logged in to the site for the same day.

If the user will log in to the site in a different browser or different system then only it will ask you for OTP. The validity of the cookies is only for 24 hours after that it will delete automatically from your browser.

Step 5: Here is the simple code to generate otp in c#.net.

how to generate otp asp.net

Step 6: Make sure you have created two tables in your database. The name of the database is OTPdb and here I have created two tables called Login_Check_SP and OTPhistortbl.

In Login_Check_Sp table: It will validate the authenticate user and OTPhistortbl is used to keep all OTP generation history of the user.

otp generator c#

Step 7: When your database gets created, next connect to your database through connection string which you have to set in web.config file.

Step 8: Here is the HTML code for the Login screen and generate OTP in C#.

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Login.aspx.cs" Inherits="Login" %>

					Forgot Username/Passwor
						
				
		        
				
		
	

        
            
                
                    
                        ×
                        Please enter phone number to receive the code 

                    
                    
                        
                    
                                         
                                              
                    
                
            
        

       
            
                
                    
                        ×
                        Please enter the OTP(One Time Password) sent to your registered mobile #:974xxxx5968 
                        This OTP will expire in 5 minutes.

                    
                    
                        
                    
                                         
                        
                        If you have not receive your OTP then click here

    protected void btnSendOTP_Click(object sender, EventArgs e)
    {
        ScriptManager.RegisterStartupScript(this, GetType(), "ServerControlScript", "", false);
    }

    protected void ValidateOTP_Click(object sender, EventArgs e)
    {
        lblMsg.Visible = true;
        adp = new SqlDataAdapter("SELECT ctime_Stamp FROM OTPhistroytbl WHERE OTP='" + txtOTP.Text + "'", con);
        adp.Fill(dt);
        DateTime OtpCrtDate = Convert.ToDateTime(dt.Rows[0][0].ToString());

        if (txtOTP.Text != randomNumber)
        {
            TimeSpan timeSub = DateTime.Now - OtpCrtDate;
            if (timeSub.TotalMinutes < 300)
            {
                cmd = new SqlCommand("update OTPhistroytbl set status='0' where OTP='" + txtOTP.Text + "'", con);
                con.Open();
                cmd.ExecuteNonQuery();
                lblMsg.Text = "logined successfully";
                con.Close();
            }
            else
            {
                lblMsg.Text = "Sorry but your OTP is very old. Get a new one";
            }
        }
        else
        {

            lblMsg.Text = "Sorry, Your OTP is Invalid. Try again, please.";
        }
    }
}

Note: For sending OTP to mobile, It may not be work for you because this key doesn’t work for you. You have to generate your own key to sending OTP to your mobile or you can use this OTP while sending in an email instead of sending as SMS in mobile.

Step 9: Please look into my OTP result in a SQL database which is shown below. Here Id, Customer_no, and User_Id should populate dynamically as I have hardcoded here.

Gridview in asp.net

Bijay — Mon, 24 Apr 2023 08:34:53 +0000

This asp.net tutorial explains, gridview in asp.net. How to bind gridview using data reader in asp.net. How to add Eval for a hyperlink in gridview in asp.net? And, how to apply color in gridview rows based dynamically.

Then we will discuss how to export gridview data to excel sheet in Asp.net? And, how to export gridview to word in asp.net c#.net. We will also discuss how to display a confirmation message in gridview for delete in Asp.net. We will also see, how to send or pass girdview row value to the next page using a hyperlink in asp.net.

Gridview in asp.net

Gridview is a control in asp.net which displays data in a tabular format. Gridview control displays the values of a data source in a table where each column represents a field and each row represents a record in asp.net. The asp.net GridView control enables you to select, sort, and edit these items.

There are different ways we can bind data to gridview in asp.net.

Bind gridview using datareader in asp.net

Now, we will see how to bind gridview using data reader in asp.net.

Below is the full code to bind gridview using a data reader in Asp.Net. Here we have used a stored procedure to retrieve data from the database:

Stored Procedure:

CREATE PROCEDURE Select_Employees

AS
BEGIN
Select * from Employees
END
GO

HTML Code:

.cs code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using System.Data.SqlClient;
using System.Configuration;

public partial class _Default : System.Web.UI.Page
{
string conn = "Data Source=localhost;database=sample;Integrated Security=true";
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
bindGridview();
}
}

private void bindGridview()
{
SqlConnection con = new SqlConnection(conn);
SqlCommand cmd = new SqlCommand("Select_Employees", con);
cmd.CommandType = CommandType.StoredProcedure;
SqlDataReader reader;
try
{
con.Open();
reader = cmd.ExecuteReader();
GridView1.DataSource = reader;
GridView1.DataBind();
reader.Close();
}
catch (Exception ex)
{
}
finally
{
con.Close();
}
}
}

But we can not implement paging in gridview with data reader in asp.net.

Bind GridView Using Dataset in Asp.Net

Now, we will see how to bind gridview using dataset in asp.net.

Below is the C#.Net code to bind gridview using dataset in asp.net.

SqlConnection con = new SqlConnection(@"Data Source=localhost;database=sample;Integrated Security=true");  
SqlCommand cmd = new SqlCommand("select * from Employees", con);  
SqlDataAdapter da = new SqlDataAdapter(cmd);  
DataSet ds = new DataSet();  
da.Fill(ds);  
GridView1.DataSource = ds;  
GridView1.DataBind();

How to add Eval for hyperlink in gridview in asp.net?

Now, we will see how to add Eval property into hyperlink field in gridview in Asp.Net.

In this scenario, we will see how a user can navigate to a different page with a query string parameter. In the below code it will see a list of usernames which are binding from the database. Then whenever a user clicks on a particular username, then it will navigate to a UserDetails page with taking UserID as a query string parameter.

Here the Text value is coming from the Eval property by the following syntax.

Text='<%#Eval("UserName")%>'

And the NavigateURL property is coming from the below property:

NavigateUrl='<%# "~/UserDetails.aspx?UserID=" + Eval("UserID")%>'

Apply color in gridview rows based dynamically

Now, we will see how to fill colors in gridview based on some conditions and values in asp.net.

Say for an example: if a gridview has different departments in different locations. Need to color the gridview values based on the locations and display the top scorers of the winner’s department wise.

Add OnRowDataBound EVENT for the gridview and the find

protected void GvLeaderBorad_OnRowDataBound(object sender, GridViewRowEventArgs e)
        {
if (e.Row.RowType == DataControlRowType.DataRow)
            {
  Label lblNett = e.Row.FindControl("lbl_Net") as Label;
                if (lblNett.Text == Locations.Chennai.ToString())
                {
                    e.Row.Cells[0].BackColor = System.Drawing.Color.DarkGreen;
                }
}
}

When the color code is fetched from label placed inside the row . It will be applied to the entire row. Thus in code itself when we bind the grid. Provide row color in the label and fetch the color code from it.

Apply the color code(Html hex code ex: #fffff ) to the gridview row.

Export gridview data to excel sheet in Asp.net

Now, we will see how to export gridview data to excel sheet in asp.net.

Below is the full code to export gridview data to excel sheet in Asp.net.

protected void btnExport_Click(object sender, EventArgs e)
{
DataSet ds = new DataSet();
ds = GetDataForGridView();
string attachment = attachment = "attachment; filename=MyExcelSheetName_" + DateTime.Now.ToString() + ".xls";
if (ds.Tables.Count > 0)
{
DataTable dt = ds.Tables[0];
Response.ClearContent();
Response.AddHeader("content-disposition", attachment);
Response.ContentType = "application/vnd.ms-excel";
string tab = "";
//This will give you the number of columns present in gridview
for (int coulumns = 0; coulumns < GridView1.Columns.Count; coulumns++)
{
Response.Write(tab + GridView1.Columns[coulumns].HeaderText);
tab = "\t";
}
Response.Write("\n");

//Here we will visit each row of datatable and bind the corresponding column data.
foreach (DataRow dr in dt.Rows)
{
tab = "";
Response.Write(tab + dr["ColumnName1"].ToString());
tab = "\t";
Response.Write(tab + dr["ColumnName2"].ToString());
tab = "\t";
Response.Write(tab + dr["ColumnName3"].ToString());
tab = "\t";
Response.Write("\n");
}
Response.End();
}
}

Export gridview to word in asp.net c#

Now, we will see how we can download or export gridview data to word document in asp.net using c#.net. Here I have developed an asp.net website where we have used a gridview to bind the data from SQL server table and then we have a button, on the button click we are exporting the data to word format.

Below is the .aspx code.

.aspx.cs code:

Below is the .cs code.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.IO;
using System.Configuration;

namespace EnjoySharePointBackup
{
public partial class _Default : Page
{

private SqlConnection con;
private SqlCommand com;
private string constr, query;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Bindgrid();

}
}
public override void VerifyRenderingInServerForm(Control control)
{
//base.VerifyRenderingInServerForm(control);
}
private void connection()
{
string constr = "Data Source=YourDataSource;database=EnjoySharePoint;User ID=User1;Password=**********;";
con = new SqlConnection(constr);
con.Open();

}
protected void btnDownload_Click(object sender, EventArgs e)
{
ExportGridToword();
}
private void Bindgrid()
{
connection();
query = "select * from jobmaster where JobID"+ TextBox1.Text;
com = new SqlCommand(query, con);
SqlDataReader dr = com.ExecuteReader();

GridView1.DataSource = dr;
GridView1.DataBind();
con.Close();

}

private void ExportGridToword()
{
Response.Clear();
Response.Buffer = true;
Response.ClearContent();
Response.ClearHeaders();
Response.Charset = "";
string FileName = "EnjoySharePoint" + DateTime.Now + ".doc";
StringWriter strwritter = new StringWriter();
HtmlTextWriter htmltextwrtter = new HtmlTextWriter(strwritter);
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = "application/msword";
Response.AddHeader("Content-Disposition", "attachment;filename=" + FileName);
GridView1.GridLines = GridLines.Both;
GridView1.HeaderStyle.Font.Bold = true;
GridView1.RenderControl(htmltextwrtter);
Response.Write(strwritter.ToString());
Response.End();
}
}
}

This way we can export gridview data to word in asp.net using c#.net.

Show confirmation message in gridview for delete in Asp.net

Now, we will see how to show a confirmation message while deleting a record from the gridview in asp.net. Like it should first as us whether you want to delete the record and then if the user clicks on yes then it should delete the record.

There are different ways to show confirmation message in gridview for delete in Asp.net.

1st Approach:

You can directly write in the OnClientClick event of the LinkButton like below:





Delete

2nd Approach:

You can write a javascript function and call that function in the OnClientClick event like below:


Show confirmation message in gridview for delete in Asp.net








Delete

This way we can display confirmation message in gridview for delete in Asp.net.

Send GridView row data to the next page using Hyperlink in Asp.Net

Now, we will see how to send or pass girdview row value to the next page using a hyperlink in asp.net.

Follow the below steps:

Add hyperlink column in the gridview control. And set the data fields to navigate to the next page in the DataNavigateUrlFields property of the hyperlink field.

Then Pass Query String value in DataNavigateUrlFormatString property of the hyperlink field.

Retrieve data in the 2nd page using Request.QueryString.

Source page of Default.aspx:

Source page of Default2.aspx:

EmployeeID:


EmployeeName:


EmployeeAddress:

Code behind page of Default2.aspx:

Protected void Page_Load( sender As Object, e As System.EventArgs)
{
String strid ;
String strname;
String stradd;

strid = Request.QueryString(“empid");
strname = Request.QueryString(“empname");
stradd = Request.QueryString(“empadd");

lblEmpId.Text = strid;
lblEmpName.Text = strname;
lblEmpAddress.Text = stradd;
}

This way we can send girdview row value to the next page using a hyperlink in asp.net.

Gridview in asp.net

Implement delete functionality in Gridview in Asp.Net

This gridview example we will discuss how to implement the delete mechanism in grid view in asp.net.

if you are showing some users and want to delete one user when someone clicks on the Delete link button inside the gridview.

Below is the full code:

Gridview code:
















Delete

Here we need to handle the OnRowDeleting and OnRowCommand command event.

In the Delete button, we have set the CommandArgument to the UserID which is the ID through which we will write the code to delete the record.

We have also set the CommandName as “Delete” which you can set anything but you need to check in the OnRowCOmmand event.

It will also ask you a confirmation message before deleting the record.

.CS Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class Default4 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGridView();
}
}
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
int UserID =Convert.ToInt32( e.CommandArgument);
if (e.CommandName == "Delete")
{
//Write your code to delete the user based on the above UserID
}
}
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
//Here no need to write any logic inside.
}

void BindGridView()
{
//Here is the code to Bind the gridview
}
}

Hope you will able to delete the record in the gridview in asp.net.

How to display serial number automatically in GridView in asp.net?

Now, we will see how to display a serial number column in grid view in asp.net.

The serial number will come as an index, it will start from 1 and will go on increasing 1 value for each row.

Here the code to bind a gridview will be the same. The only thing will change is we need to another like below:





<%# Container.DataItemIndex + 1 %>

If you will write this code then the serial number column will come in Gridview.

How to use jquery modal popup in asp.net

Bijay — Mon, 24 Apr 2023 07:18:16 +0000

In this asp.net tutorial, we will discuss how to use jQuery modal popup in Asp.Net. Here, we will discuss how to display a successful message in a popup to the user.

jQuery modal popup Asp.Net

To use jQuery modal popup in Asp.Net we need to first add the jQuery reference on the page.

And next, you can create the dialog that will call the dialog box on a button click.

Step 1: Add the jQuery reference on your page or you can take the below reference file.

Step 2: Now we will create a method where you will add your dialog with the below option.

jquery modal popup in asp.net

 function showmodalpopup() {
        $("#popupdiv").dialog({
            width: 500,
            height: 250,
            modal: true,
            hide: { effect: 'drop', duration: 250 },
            resizable: false,
            draggable: false,
            position: "center",
            closeOnEscape: true
        });
    };

Step 3: Next, I added a Div where you can call this dialog using Div ID.

                  <%=GetLocalResourceObject("lbResult") %>

Step 4: Here I have added a few CSS files which you can take as your reference to apply some style in your Popup.

jquery modal popup example

.ui-dialog-titlebar {
    background-color: #80c342;
    padding: 5px;
    color: white;
    height: 20px;
    font-weight: bold;
    font-size: 13px;
    width: 490px;
}
    .ResultSuccess{
        font-weight: bold;
        font-size: 20px;
    }
   .ui-dialog-titlebar-close {
    visibility: hidden;
    }

Step 5: Now I am calling this showmodalpopup() from server-side after data successfully inserted in the table.

 ScriptManager.RegisterStartupScript(this, GetType(), "Success", "showmodalpopup();", true);

In my submit button click, I called this method if my record inserted successfully. So once data inserted you will get a popup message like the below screenshot.

jquery modal popup asp.net

Here you can also add a close button to close the dialog. So you need to add the below code.

buttons: {
                Close: function () {
                    $(this).dialog('close');
                }
            }

Benefits Of Choosing .NET

.NET facilitates a business application development process in several ways such as – reducing development time and effort, flexibility, and so on. Get explained information here.

Code Reuse And Less Coding

While working on this particular framework, the professionals do not need to generate new codes again and again. The system works by eliminating unnecessary coding requirements.

Another major factor is the benefit of reusing the code. There are many components and codes available that can be re-used to form a new software. It benefits by saving time and money in business application development.

Adaptability

.NET provides complete flexibility while choosing a language for software development. It supports multiple languages like –

C#
F#
C++
COBOL
Visual Basics

There are numerous other languages that can be used with .NET. It is managed and completed by the CLR for keeping all framework related aspects perfect such as – memory and security.

The selection of development language is based on the framework’s requirements that you want to create for business applications.

How to Implement Log4Net in ASP.NET Core Application

Bijay — Mon, 24 Apr 2023 06:43:26 +0000

In this asp.net tutorial, we will discuss how to implement Log4Net in ASP.NET Core Application. Step by step I will explain how to use Log4Net in the Asp.Net core application.

ASP.NET core is an open-source, cross-platform, and modular framework for building modern and high-performance applications. .NET Core SDK is a lightweight SDK that includes a minimum set of features required to build an application. We can install other features from NuGet packages.

.NET Core provides programming patterns such as dependency injection, logging, and app configuration. For logging, it includes Microsoft.Extension.Logging package. It will store the logs for display. In this blog, we will learn about Log4Net logging in Asp.net Core.

What is Logging?

Logging is a modern and one of the in-built features in ASP.NET Core application for detecting issues. ASP.NET Core supports a wide variety of logging providers. You can plug in your own frameworks like Log4Net, Elmah, and NLog. Microsoft.Extension.Logging namespace provides supports for simple logging with just a few lines of code.

For ASP.NET Core 1.x, you need to include the dependencies explicitly for your project and these dependencies are built-in for ASP.NET Core 2.x.

Built-in classes and interface in Microsoft.Extension.Logging namespace as follow:

ILogger
ILoggerFactory
LoggerFactory
ILoggerProvider

ILoggerFactory:

ILoggerFactory interface creates an ILogger instance and also adds an ILoggerProvider instance. In Asp.net Core includes a built-in LoggerFactory class that implements the ILoggerFactory interface.

using Microsoft.Extensions.Logging;

namespace Log4NetExample.Log
{
    interface ILoggerFactory : IDisposable
    {
        ILogger CreateLog(string name);
        void LogProvider(ILoggerProvider provider);
    }
}

We can use this interface for creating ILogger instance and add ILoggerProvider instance.

ILoggerProvider:

ILoggerProvider creates a suitable ILogger instance and manage it. We can create our own custom logging provider by implementing ILoggerProvider interface.

using Microsoft.Extensions.Logging;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace Log4NetExample.Log
{
    interface ILoggerProvider : IDisposable
    {
        ILogger CreateLog(string name);
    }
}

ILogger:

For logging, ILogger interface includes the methods to store it. There are many extension methods for logging which make it easy.

using Microsoft.Extensions.Logging;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace Log4NetExample.Log
{
    interface ILogger
    {
        void Log(LogLevel logLvl, EventId evntId, TState state, Exception         exception, Func formatter);
        bool IsEnabled(LogLevel logLvl);
        IDisposable BeginScope(TState state);
    }
}

In ILogger, there are 3 methods.

BeginScope: – It initiates the logical operation scope.
IsEnabled: – It checks if the log level is enabled or not.

Logging Providers: –

For store and display logs logging providers use a certain medium such as console level, debug level, and event log etc. Microsoft provides an extension or namespace for various logging providers from NuGet package.

Microsoft also team up with the third parties logging framework such as NLog, Serilog, Log4Net, elmah and others.

Basic Configuration Example

Let’s take example using Log4Net.

Step-1: Install Log4Net

PM> Install-Package Microsoft.Extensions.Logging.Log4Net.AspNetCore -Version 2.1.0

Step-2: Update Start up file

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory logger)
     {
           logger.AddLog4Net();
      }

Step 3: Add Log.config File

Add our own custom .config file as illustrates below.

Rolling File Appender:

Debug Level:

We can define log level and Appender-ref into root element. Root element is necessary in the config file.

We have taken here the RollingLogAppender but there are also other types such as FileAppender, ConsoleAppender. This is the basic configuration in the Asp.net Core application. We can add custom configuration using Log4Net Providers as illustrates below.

Custom Configuration Using Log4NetProviders

Step 1: appsettings file Install the package in your Asp.net Core application and add Log4Net in the appsettings.json file.

{
  "Log4NetExample": {
    "Name": "Test",
    "LoggerRepository": "Real",
    "OverrideCriticalLevelWith": "Fatal",
    "Watch": false,
    "UseWebOrAppConfig": false,
    "PropertyOverrides": [
      {
        "XPath": "/log4net/appender[@name='RollingFile']/file",
        "Attributes": {
          "Value": "overridedFileName.log"
        }
      },
      {
        "XPath": "/log4net/appender[@name='RollingFile']/maximumFileSize",
        "Attributes": {
          "Value": "200MB"
        }
      },
      {
        "XPath": "/log4net/appender[@name='RollingFile']/file"
      }
    ]
  }
}

Step 2: Place appsetting in program.cs file

Add appsetting.json file in configuration builder method as below. For that, we need to install the Microsoft.Extension.Configuration.Json package.

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.Logging;

namespace Log4Net
{
    public class Program
    {
        public static void Main(string[] args)
        {
            CreateWebHostBuilder(args).Build().Run();
        }

        public static IWebHostBuilder CreateWebHostBuilder(string[] args)
        {
            var config = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())
            .AddJsonFile("appsettings.json")
            .Build();

            return WebHost.CreateDefaultBuilder(args)
                .UseConfiguration(config)
                .UseStartup();
        }            
    }
}

Step 3: Add log4Net in startup file

Add Log4Net to startup file and configure it.

var loggingOptions = this.Configuration.GetSection("Log4NetCore")
                                               .Get();
            logger. AddLog4Net ();

Complete Startup file as shown below:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.HttpsPolicy;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;

namespace Log4Net
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        public void ConfigureServices(IServiceCollection services)
        {
            services.Configure(options =>
            {
                options.CheckConsentNeeded = context => true;
                options.MinimumSameSitePolicy = SameSiteMode.None;
            });
            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
        }
        public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory logger)
        {
            var loggingOptions = this.Configuration.GetSection("Log4NetExample")
                                               .Get();
            logger.AddLog4Net();

            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
                app.UseHsts();
            }

            app.UseHttpsRedirection();
            app.UseStaticFiles();
            app.UseCookiePolicy();

            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });
        }
    }
}

You have seen the Log4NetProviderOptions in Configuration.GetSection method. There are some properties that we have described below.

Implement Log4Net in ASP.NET Core Application

Properties of Log4NetProviderOptions

UseWebOrAppConfig – Boolean value that indicate the Log4Net Configuration Section is in the app.config file or in web.config file and its default value is false.
ExternalConfigurationSetup – This setup indicates that the Log4Net library has been configured outside the extension using XmlConfigurator and its default value is false.
Watch – This property indicates that the Log4Net.config file will be opened in watch mode and likewise its default value is false.
PropertyOverrides – During Log4Net initialization it allows to replacement of defined value.

Conclusion

Logging API works with other logging providers. Logging providers display to store the log in console level, debug level, an event log, and other types of the medium. All logging providers reside in Microsoft.Extension.Logging namespace. Such as Logging.Console, Logging.Debug, Logging.EventLog, and others. In this blog, we have seen the basic configuration and custom configuration. Also, we have created log.config using the rolling appender and debug level.
