Calendar::OnSelectionChanged Method
Raises the SelectionChanged event of the Calendar control and allows you to provide a custom handler for the SelectionChanged event.
Assembly: System.Web (in System.Web.dll)
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.
