The following code provides an example of configuring a Calendar so that multiple ranges of dates can be selected. This example is part of a larger example available in the Calendar overview.

'Sets a Calendar to allow multiple selections, and configures 
'some dates to be unselectable. 
cal3.SelectionMode = CalendarSelectionMode.MultipleRange
cal3.DisplayDate = New DateTime(2009, 1, 1)
cal3.DisplayDateStart = New DateTime(2009, 1, 1)
cal3.DisplayDateEnd = New DateTime(2009, 1, 31)
cal3.BlackoutDates.Add(New CalendarDateRange(New DateTime(2009, 1, 2), New DateTime(2009, 1, 4)))
cal3.BlackoutDates.Add(New CalendarDateRange(New DateTime(2009, 1, 9)))
cal3.BlackoutDates.Add(New CalendarDateRange(New DateTime(2009, 1, 16)))
cal3.BlackoutDates.Add(New CalendarDateRange(New DateTime(2009, 1, 23), New DateTime(2009, 1, 25)))
cal3.BlackoutDates.Add(New CalendarDateRange(New DateTime(2009, 1, 30)))

cal3.SelectedDates.Add(New DateTime(2009, 1, 5))
cal3.SelectedDates.AddRange(New DateTime(2009, 1, 12), New DateTime(2009, 1, 15))
cal3.SelectedDates.Add(New DateTime(2009, 1, 27))

//Sets a Calendar to allow multiple selections, and configures
//some dates to be unselectable.
cal3.SelectionMode = CalendarSelectionMode.MultipleRange;
cal3.DisplayDate = new DateTime(2009, 1, 1);
cal3.DisplayDateStart = new DateTime(2009, 1, 1);
cal3.DisplayDateEnd = new DateTime(2009, 1, 31);
cal3.BlackoutDates.Add(new CalendarDateRange(new DateTime(2009, 1, 2), new DateTime(2009, 1, 4)));
cal3.BlackoutDates.Add(new CalendarDateRange(new DateTime(2009, 1, 9)));
cal3.BlackoutDates.Add(new CalendarDateRange(new DateTime(2009, 1, 16)));
cal3.BlackoutDates.Add(new CalendarDateRange(new DateTime(2009, 1, 23), new DateTime(2009, 1, 25)));
cal3.BlackoutDates.Add(new CalendarDateRange(new DateTime(2009, 1, 30)));

cal3.SelectedDates.Add(new DateTime(2009, 1, 5));
cal3.SelectedDates.AddRange(new DateTime(2009, 1, 12), new DateTime(2009, 1, 15));
