This property determines whether the Calendar allows no selection, selection of a single date, or selection of multiple dates. The selection mode is specified with the CalendarSelectionMode enumeration.
When this property is changed, all selected dates will be cleared.
The following example creates a Calendar that has multiple ranges of dates selected.
// Create a Calendar that displays dates through // Januarary 31, 2009 and has dates that are not selectable. 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( new CalendarDateRange(new DateTime(2009, 1, 30))); // Add the selected dates. calendarWithBlackoutDates.SelectedDates.Add( new DateTime(2009, 1, 5)); calendarWithBlackoutDates.SelectedDates.AddRange( new DateTime(2009, 1, 12), new DateTime(2009, 1, 15)); calendarWithBlackoutDates.SelectedDates.Add( new DateTime(2009, 1, 27)); // root is a Panel that is defined elswhere. root.Children.Add(calendarWithBlackoutDates);
