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

Create an object of DataGridViewComboBoxColumn.

  1. DataGridViewComboBoxColumn dgvCmb = new DataGridViewComboBoxColumn();

Give the Header name to the DataGridViewComboboxColumn for the DataGridView.

  1. dgvCmb.HeaderText ="Name";

Now add the items into the ComboBox.

  1. dgvCmb.Items.Add("Ghanashyam");
  2. dgvCmb.Items.Add("Jignesh");
  3. dgvCmb.Items.Add("Ishver");
  4. dgvCmb.Items.Add("Anand");

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

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

The whole code :

  1. using System;
  2. using System.Windows.Forms;
  4. namespace DataGridView
  5. {
  6. public partial class Form1 : Form
  7. {
  8. public Form1()
  9. {
  10. InitializeComponent();
  11. }
  13. private void btn_Click(object sender, EventArgs e)
  14. {
  15. DataGridViewComboBoxColumn dgvCmb = new DataGridViewComboBoxColumn();
  16. dgvCmb.HeaderText ="Name";
  17. dgvCmb.Items.Add("Ghanashyam");
  18. dgvCmb.Items.Add("Jignesh");
  19. dgvCmb.Items.Add("Ishver");
  20. dgvCmb.Items.Add("Anand");
  21. dgvCmb.Name="cmbName";
  22. myDataGridView.Columns.Add(dgvCmb);
  23. }
  24. }
  25. }

Code For Adding CheckBox Into the DataGridView at Runtime.

First of all create the object of the DataGridViewCheckBoxColumn.

  1. DataGridViewCheckBoxColumn dgvChb = new DataGridViewCheckBoxColumn();

Then set the header text for that CheckBox for DataGridView.

  1. dgvChb.HeaderText = "Pass";

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

  1. 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.

  1. 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".

  1. dgvChb.ThreeState = true;

See the following image.

Finally add that CheckBox into the DataGridView.

  1. myDataGridView.Columns.Add(dgvChb);

See the whole code:

  1. using System;
  2. using System.Windows.Forms;
  4. namespace DataGridView
  5. {
  6. public partial class Form1 : Form
  7. {
  8. public Form1()
  9. {
  10. InitializeComponent();
  11. }
  13. private void btn_Click(object sender, EventArgs e)
  14. {
  15. DataGridViewCheckBoxColumn dgvChb = new DataGridViewCheckBoxColumn();
  16. dgvChb.HeaderText = "Pass";
  17. dgvChb.Name = "chbPass";
  18. dgvChb.FlatStyle = FlatStyle.Standard;
  19. dgvChb.ThreeState = true;
  20. dgvChb.CellTemplate.Style.BackColor = System.Drawing.Color.LightBlue;
  21. myDataGridView.Columns.Add(dgvChb);
  22. }
  23. }
  24. }

Hope this is clear to you guys.
