DataGridViewLinkColumn & DataGridViewButtonColumn in C#

In this article you will learn how to add a DataGridViewLinkColumn & DataGridViewButtonColumn in a DataGridView at runtime & how to access the click event of the added columns.

Code For Add LinkColumn in DataGridView at Runtime:

First of all I have added two columns named "User ID" & "Password".

myDataGridView.ColumnCount = 2; myDataGridView.Columns[0].Name = "User ID"; myDataGridView.Columns[1].Name = "Password";

Then add rows with the data:

string[] row = new string[] { "abc", "abc"}; myDataGridView.Rows.Add(row); row = new string[] { "pqr", "pqr"}; myDataGridView.Rows.Add(row); row = new string[] { "ghanashyam", "ghanashyam"}; myDataGridView.Rows.Add(row); row = new string[] { "jignesh", "jignesh"}; myDataGridView.Rows.Add(row);

I have added a total of 4 rows with User Ids & Passwords.

Then take an object of the DataGridViewLinkColumn.

DataGridViewLinkColumn dgvLink = new DataGridViewLinkColumn();

Then set all needed properties.

dgvLink.UseColumnTextForLinkValue = true; dgvLink.LinkBehavior = LinkBehavior.SystemDefault; dgvLink.HeaderText = "Link Data"; dgvLink.Name = "SiteName"; dgvLink.LinkColor = Color.Blue; dgvLink.TrackVisitedState = true; dgvLink.Text = "http://www.c-sharpcorner.com"; dgvLink.UseColumnTextForLinkValue = true;

Finally add that column to the DataGridView:
 

myDataGridView.Columns.Add(dgvLink);

You can access that LinkColumn by clicking on it:
 

private void myDataGridView_CellContentClick(object sender, DataGridViewCellEventArgs e) {     if (e.ColumnIndex == 2)     {         //Write here your code...     } }

See the following image:

The whole code:

using System; using System.Windows.Forms; using System.Drawing; namespace DataGridView {     public partial class Form1 : Form     {         public Form1()         {             InitializeComponent();         }        private void btn_Click(object sender, EventArgs e)         {             myDataGridView.Columns.Clear();             myDataGridView.ColumnCount = 2;             myDataGridView.Columns[0].Name = "User ID";             myDataGridView.Columns[1].Name = "Password";             string[] row = new string[] { "abc", "abc"};             myDataGridView.Rows.Add(row);             row = new string[] { "pqr", "pqr"};             myDataGridView.Rows.Add(row);             row = new string[] { "ghanashyam", "ghanashyam"};             myDataGridView.Rows.Add(row);             row = new string[] { "jignesh", "jignesh"};             myDataGridView.Rows.Add(row);             DataGridViewLinkColumn dgvLink = new DataGridViewLinkColumn();             dgvLink.UseColumnTextForLinkValue = true;             dgvLink.LinkBehavior = LinkBehavior.SystemDefault;             dgvLink.HeaderText = "Link Data";             dgvLink.Name = "SiteName";             dgvLink.LinkColor = Color.Blue;             dgvLink.TrackVisitedState = true;             dgvLink.Text = "http://www.c-sharpcorner.com";             dgvLink.UseColumnTextForLinkValue = true;             myDataGridView.Columns.Add(dgvLink);         }         private void myDataGridView_CellContentClick(object sender, DataGridViewCellEventArgs e)         {             if (e.ColumnIndex == 2)             {                 //Write here your code...             }         }     } }

 
Code For Add ButtonColumn in DataGridView at Runtime:

As per the above code I have added the two columns named "User ID" & "Password" into the DataGridView & added rows.

Now create the object of the DataGridViewButtonCloumn:

DataGridViewButtonColumn dgvButton = new DataGridViewButtonColumn();

Then set all related properties of the button Column:
 

dgvButton.FlatStyle= FlatStyle.Flat; dgvButton.HeaderText = "Button"; dgvButton.Name = "Button"; dgvButton.UseColumnTextForButtonValue = true; dgvButton.Text = "New";

Finally add that ButtonColumn into the DataGridView.
 

myDataGridView.Columns.Add(dgvButton);

You can also access that button click event & write your own code:
 

private void myDataGridView_CellContentClick(object sender, DataGridViewCellEventArgs e) {     if (e.ColumnIndex == 2)     {         //Write here your code...         MessageBox.Show("You Have Selected " + (e.RowIndex + 1).ToString() + " Row Button");    } }

See the following images:

  
 

Click on the 2nd row Button:

  
 

Display message:

 

There are a total of four kinds of FlatStyles.

See the following all four kinds of FlatStyles: 

1. Flat Style:
    
   a.  This kind of FlatStyle's image is displayed above the image.
   b.  dgvButton.FlatStyle= FlatStyle.Flat;
    

2. System:
   
   a.  dgvButton.FlatStyle= FlatStyle.System;
    
   
    

3. Popup:
   
   a.  dgvButton.FlatStyle= FlatStyle.Popup;
    
   
    
    

4. Standard:
   
   a.  dgvButton.FlatStyle= FlatStyle.Standard;
   
   
     
    

 

The whole code:
 

using System; using System.Windows.Forms; using System.Drawing; namespace DataGridView {     public partial class Form1 : Form     {         public Form1()         {             InitializeComponent();         }         private void btn_Click(object sender, EventArgs e)         {             myDataGridView.Columns.Clear();             myDataGridView.ColumnCount = 2;             myDataGridView.Columns[0].Name = "User ID";             myDataGridView.Columns[1].Name = "Password";             string[] row = new string[] { "abc", "abc"};             myDataGridView.Rows.Add(row);             row = new string[] { "pqr", "pqr"};             myDataGridView.Rows.Add(row);             row = new string[] { "ghanashyam", "ghanashyam"};             myDataGridView.Rows.Add(row);             row = new string[] { "jignesh", "jignesh"};             myDataGridView.Rows.Add(row);             DataGridViewButtonColumn dgvButton = new DataGridViewButtonColumn();             dgvButton.FlatStyle= FlatStyle.System;             dgvButton.HeaderText = "Button";             dgvButton.Name = "Button";             dgvButton.UseColumnTextForButtonValue = true;             dgvButton.Text = "New";             myDataGridView.Columns.Add(dgvButton);         }         private void myDataGridView_CellContentClick(object sender, DataGridViewCellEventArgs e)         {             if (e.ColumnIndex == 2)             {                 //Write here your code...                 MessageBox.Show("You Have Selected " + (e.RowIndex + 1).ToString() + " Row Button");             }         }     } }

Hope this is clear to you.
