Hi you mean to say deselect check box on dialogResult.NO right? if (dr == DialogResult.Yes) { // your logic..... } else { for (int i = 0; i { row = gridviewimppays.Rows[i]; ((DataGridViewCheckBoxCell)row.Cells[0]).value = false; } } hope this will help you.

Your code seems to work fine and since you've already checked for dr==DialogResult.yes it ensures that your code executes only when the user selected yes on messagebox.
