Calendar.SelectedDates Property


Gets a collection of selected dates.

Namespace:   System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)

public SelectedDatesCollection SelectedDates { get; }

Property Value

Type: System.Windows.Controls.SelectedDatesCollection

A SelectedDatesCollection object that contains the currently selected dates. The default is an empty collection.

Dates can be added to the collection either individually or in a range using the AddRange method. Depending on the value of the SelectionMode property, adding a date or range to the collection may cause it to be cleared. The following table lists how CalendarSelectionMode affects the SelectedDates property.




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.



One or more DateTime object elements.
