Add CheckBox to C# DataGridView

The DataGridView control and its related classes are designed to be a flexible, extensible system for displaying and editing tabular data. The DataGridView control provides TextBox, CheckBox, Image, Button, ComboBox and Link columns with the corresponding cell types. While adding a CheckBox in a cell, the cell Value property can be set explicitly through programmatic code that accesses the cell in the Cells collection of the row, or it can be set through data binding.

The following C# program shows how to add a CheckBox in Cell of a DataGridView control and set the third row checkbox value as true.

using System.Data;
using System.Windows.Forms;
using System.Data.SqlClient;

namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            dataGridView1.ColumnCount = 3;
            dataGridView1.Columns[0].Name = "Product ID";
            dataGridView1.Columns[1].Name = "Product Name";
            dataGridView1.Columns[2].Name = "Product Price";

            string[] row = new string[] { "1", "Product 1", "1000" };
            dataGridView1.Rows.Add(row);
            row = new string[] { "2", "Product 2", "2000" };
            dataGridView1.Rows.Add(row);
            row = new string[] { "3", "Product 3", "3000" };
            dataGridView1.Rows.Add(row);
            row = new string[] { "4", "Product 4", "4000" };
            dataGridView1.Rows.Add(row);
            
            DataGridViewCheckBoxColumn chk = new DataGridViewCheckBoxColumn();
            dataGridView1.Columns.Add(chk);
            chk.HeaderText = "Check Data";
            chk.Name = "chk";
            dataGridView1.Rows[2].Cells[3].Value = true;
        }
    }
