DataGridViewLinkColumn & DataGridViewButtonColumn in C#

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:

xusing 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.
