Assembly:  System.Web (in System.Web.dll)

member SelectedDates : SelectedDatesCollection with get

Property Value

Type: System.Web.UI.WebControls.SelectedDatesCollection
A SelectedDatesCollection that contains a collection of System.DateTime objects representing the selected dates on the Calendar. The default value is an empty SelectedDatesCollection.

Use the SelectedDates collection to determine the currently selected dates on the Calendar control.

The SelectedDate property and the SelectedDates collection are closely related. When the SelectionMode property is set to CalendarSelectionMode.Day, a mode that allows only a single date selection, SelectedDate and SelectedDates[0] have the same value and SelectedDates.Count equals 1. When the SelectionMode property is set to CalendarSelectionMode.DayWeek or CalendarSelectionMode.DayWeekMonth, modes that allows multiple date selections, SelectedDate and SelectedDates[0] have the same value.

The SelectedDates property stores a collection of System.DateTime objects.

When the user selects a week or month on the Calendar control, the SelectionChanged event is raised. The selected dates are added to the SelectedDates collection, replacing the previous contents. The range of dates are sorted in ascending order by date. The SelectedDate property is also updated to contain the first date in the SelectedDates collection.

You can also use the SelectedDates collection to programmatically select dates on the Calendar control. Use the Add, Remove, Clear, and SelectRange methods to programmatically manipulate the selected dates in the SelectedDates collection.

NoteNote

Both the SelectedDate property and the SelectedDates collection are updated before the SelectionChanged event is raised. You can override the date selection by using the OnSelectionChanged event handler to manually set the SelectedDates collection. The SelectionChanged event is not raised when this collection is programmatically set.

The following code example demonstrates how to use the SelectedDates collection to determine the selected dates on the Calendar control.
