private void chkbox_CheckedChanged(object sender EventArgs e) { foreach (DataGridViewRow row in dataGridView1.Rows) { DataGridViewCheckBoxCell chk = (DataGridViewCheckBoxCell)row.Cells[1]; // set cell index of your checkbox position in datagrid if (chk.Value == chk.TrueValue) { chk.Value = chk.FalseValue; } else { chk.Value = chk.TrueValue; } } }

You can change the value Checked of the checkbox to true or false to change it to checked or unchecked. checkBox.Checked = true; Read this MSDN guide for more.
