txtEndDate.Text = dt.ToString("yyyy/MM/dd");
DateTime Date1 = Convert.ToDateTime(txtStartDate.Text);
DateTime Date2 = Convert.ToDateTime(txtEndDate.Text);
//int Datediff = ((Date2.Year - Date1.Year) * 12) + Date1.Month - Date2.Month;
int DayDiff = (Date2.Date - Date1.Date).Days;
Label1.Text = "Total days" + " " + (DayDiff.ToString());
