  Calendar calendarWithBlackoutDates = new Calendar();
  calendarWithBlackoutDates.IsTodayHighlighted = false;
  calendarWithBlackoutDates.DisplayDate = new DateTime(2009, 1, 1);
  calendarWithBlackoutDates.DisplayDateEnd = new DateTime(2009, 1, 31);
  calendarWithBlackoutDates.SelectionMode = CalendarSelectionMode.MultipleRange;

  // Add the dates that are not selectable.
  calendarWithBlackoutDates.BlackoutDates.Add(
      new CalendarDateRange(new DateTime(2009, 1, 2), new DateTime(2009, 1, 4)));
  calendarWithBlackoutDates.BlackoutDates.Add(
      new CalendarDateRange(new DateTime(2009, 1, 9)));
  calendarWithBlackoutDates.BlackoutDates.Add(
      new CalendarDateRange(new DateTime(2009, 1, 16)));
  calendarWithBlackoutDates.BlackoutDates.Add(
      new CalendarDateRange(new DateTime(2009, 1, 23), new DateTime(2009, 1, 25)));
  calendarWithBlackoutDates.BlackoutDates.Add(
