Calendar.OnSelectionChanged Method

Raises the SelectionChanged event of the Calendar control and allows you to provide a custom handler for the SelectionChanged event.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

virtual void OnSelectionChanged ()
protected void OnSelectionChanged ()
protected function OnSelectionChanged ()
Not applicable.

The SelectionChanged event is raised when the user selects a day, a week, or an entire month by clicking the date selector controls.

Raising an event invokes the event handler through a delegate. For more information, see Events and Delegates.

The OnSelectionChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors: When overriding OnSelectionChanged in a derived class, be sure to call the base class's OnSelectionChanged method so that registered delegates receive the event.

The following code example demonstrates how to specify and code a handler for the SelectionChanged event to display the number of items selected in the Calendar control.
