In this article, you will know how to add a ComboBox & CheckBox into the DataGridView at runtime.

Create an object of DataGridViewComboBoxColumn.

DataGridViewComboBoxColumn dgvCmb = new DataGridViewComboBoxColumn();

Give the Header name to the DataGridViewComboboxColumn for the DataGridView.

dgvCmb.HeaderText ="Name";

Now add the items into the ComboBox.

dgvCmb.Items.Add("Ghanashyam");
dgvCmb.Items.Add("Jignesh");
dgvCmb.Items.Add("Ishver");
dgvCmb.Items.Add("Anand");

Give the name to that ComboBox to refer to it from the DataGridView.

dgvCmb.Name="cmbName";
Finally add that newly created ComboBox into the DataGridView.
myDataGridView.Columns.Add(dgvCmb);

The whole code :

using System;
using System.Windows.Forms;
namespace DataGridView
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void btn_Click(object sender, EventArgs e)
{
DataGridViewComboBoxColumn dgvCmb = new DataGridViewComboBoxColumn();
dgvCmb.HeaderText ="Name";
dgvCmb.Items.Add("Ghanashyam");
dgvCmb.Items.Add("Jignesh");
dgvCmb.Items.Add("Ishver");
dgvCmb.Items.Add("Anand");
dgvCmb.Name="cmbName";
myDataGridView.Columns.Add(dgvCmb);
}
}
}

See the following image.

Code For Adding CheckBox Into the DataGridView at Runtime.

First of all create the object of the DataGridViewCheckBoxColumn.

DataGridViewCheckBoxColumn dgvChb = new DataGridViewCheckBoxColumn();

Then set the header text for that CheckBox for DataGridView.

dgvChb.HeaderText = "Pass";

Then set the name of that CheckBox for use in the DataGridView.

dgvChb.Name = "chbPass";

You can set the flat style of the CheckBox for the style the CheckBox will be displayed. The default flat style is standard.

dgvChb.FlatStyle = FlatStyle.Standard;

There are four different flat styles. See the following images:

1) FlatStyle is Flat.

2) FlatStyle is Popup.

3) FlatStyle is Stsndard.

4) FlatStyle is System.

You can also set the ThreeState CheckBox. In that there are a total of three kinds of states available & the user can set any one of them.

Assume that there are three states such as "Pass", "Fail" & "Backlog".

dgvChb.ThreeState = true;

See the following image.

Finally add that CheckBox into the DataGridView.

myDataGridView.Columns.Add(dgvChb);

See the whole code:

using System;
using System.Windows.Forms;
namespace DataGridView
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void btn_Click(object sender, EventArgs e)
{
DataGridViewCheckBoxColumn dgvChb = new DataGridViewCheckBoxColumn();
dgvChb.HeaderText = "Pass";
dgvChb.Name = "chbPass";
dgvChb.FlatStyle = FlatStyle.Standard;
dgvChb.ThreeState = true;
dgvChb.CellTemplate.Style.BackColor = System.Drawing.Color.LightBlue;
myDataGridView.Columns.Add(dgvChb);
}
}
}

Hope this is clear to you guys.
