Hi,
you mean to say deselect check box on dialogResult.NO right?
if (dr == DialogResult.Yes)
{
// your logic.....
}
else
{
for (int i = 0; i < gridviewimppays.Rows.Count; 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.
