Try something like: protected void Calendar1_SelectionChanged(object sender EventArgs e) { DateTime dob = Calendar1.SelectedDate; TxtDob.Text = dob.ToShortDateString(); TxtAge.Text = CalculateAge(dob).ToString(); } static int CalculateAge(DateTime dob) { DateTime now = DateTime.Today; int years = now.Year - dob.Year; if (now.Month > dob.Month) return years; if (now.Month if (now.Day >= dob.Day) return years; return --years; }
