Dates can be added to the SelectedDates property of a Calendar. Depending on the value of the Calendar::SelectionMode property, adding a date or a range to the SelectedDatesCollection may cause it to be cleared. The following table lists how CalendarSelectionMode affects the SelectedDates property.
CalendarSelectionMode | Effect on SelectedDates |
|---|---|
No selections are allowed. SelectedDate cannot be set and no values can be added to SelectedDates. | |
Only a single date can be selected, either by setting SelectedDate or the first value in SelectedDates. AddRange cannot be used. | |
A single range of dates can be selected. Setting SelectedDate, adding a date individually to SelectedDates, or using AddRange will clear all previous values from SelectedDates. | |
Multiple non-contiguous ranges of dates can be selected. Adding a date individually to SelectedDates or using AddRange will not clear SelectedDates. Setting SelectedDate will still clear SelectedDates, but additional dates or ranges can then be added. Adding a range that includes some dates that are already selected or overlaps with another range results in the union of the ranges and does not cause an exception. |
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 Margin="20" SelectionMode="MultipleRange" IsTodayHighlighted="false" DisplayDate="1/1/2009" DisplayDateEnd="1/31/2009" xmlns:sys="clr-namespace:System;assembly=mscorlib"> <Calendar.BlackoutDates> <CalendarDateRange Start="1/2/2009" End="1/4/2009"/> <CalendarDateRange Start="1/9/2009" End="1/9/2009"/> <CalendarDateRange Start="1/16/2009" End="1/16/2009"/> <CalendarDateRange Start="1/23/2009" End="1/25/2009"/> <CalendarDateRange Start="1/30/2009" End="1/30/2009"/> </Calendar.BlackoutDates> <Calendar.SelectedDates> <sys:DateTime>1/5/2009</sys:DateTime> <sys:DateTime>1/12/2009</sys:DateTime> <sys:DateTime>1/14/2009</sys:DateTime> <sys:DateTime>1/13/2009</sys:DateTime> <sys:DateTime>1/15/2009</sys:DateTime> <sys:DateTime>1/27/2009</sys:DateTime> <sys:DateTime>4/2/2009</sys:DateTime> </Calendar.SelectedDates> </Calendar>
