Problem in validation DataTime Picker in c#

Hi Naim,

You can use datetimepicker's Closeup event to do that.


        private void dateTimePicker1_CloseUp(object sender, EventArgs e)
        {
            if (dateTimePicker1.Value < DateTime.Today)
            {
                MessageBox.Show("Date cannot be less than today!");
                dateTimePicker1.Value = DateTime.Today;
            }
        }
