Hi Naim,

In the closeup event of datetime picker you can write the following code.

        private void dtp_cheque_date_CloseUp(object sender, EventArgs e)
        {

            if (dtp_cheque_date.Value < DateTime.Today)
            {
                MessageBox.Show("Cheque Date cannot be less than today!");
                dtp_cheque_date.Value = DateTime.Today;
                return;
            }
            if (dtp_cheque_date.Value > (DateTime.Today.AddDays(180)))
            {
                MessageBox.Show("Cheque Date cannot be greater than 180 days from today!");
                dtp_cheque_date.Value = DateTime.Today;
            }
        }

Or you can set the maxdate of datetimepicker. But it will not display any error message to the user.

dtp_cheque_date.MaxDate = DateTime.Today.AddDays(180);
