Source Code

public static void CalendarSelectWeek(System.Web.UI.WebControls.Calendar myControl)
{
if (myControl.SelectedDates.Count == 1)
 // the user has only selected the day, need to select the week that day is in
 {
 System.DateTime tmpDate = myControl.SelectedDate;
 DayOfWeek myFirstDayOfWeek;
 //if the first day of week for calendar control is default, then that's not a day so change it to monday
 if (myControl.FirstDayOfWeek == System.Web.UI.WebControls.FirstDayOfWeek.Default)
 {
 myFirstDayOfWeek = (DayOfWeek) System.Web.UI.WebControls.FirstDayOfWeek.Monday;
 }
 else
 {
 myFirstDayOfWeek = (DayOfWeek) myControl.FirstDayOfWeek;
 }
 //loop back till we have the first day of the week
 while (myFirstDayOfWeek != tmpDate.DayOfWeek)
 {
 tmpDate = tmpDate.AddDays(-1);
 }
 myControl.SelectedDates.Clear();
 //go through the week adding it to the selected dates
 for (int i = 0; i <= 6; i++)
 {
 myControl.SelectedDates.Add(tmpDate.AddDays(i));
 }
 }
}
