On Android and iOS the currently selected date can be reset by setting RadCalendar's SelectedDate property to null. The currently selected date gets deselected in the GUI and, most importantly, the "CalendarOnSelectionChanged" event can be raised again when the same date gets selected again in the GUI right afterwards. This is not the case on the UWP. The selected date does not get deselected and the CalendarOnSelectionChanged does not get raised when the same date gets selected again in the GUI. We tested it using the Telerik_UI_for_Xamarin_2017_1_1220_4_Dev build.

See attached file for more details.
