ListControl.OnSelectedIndexChanged Method
.NET Framework 3.0
Raises the SelectedIndexChanged event. This allows you to provide a custom handler for the event.
Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)
Assembly: System.Web (in system.web.dll)
The SelectedIndexChanged event is raised when the selection from the list control changes between posts to the server.
Note: |
|---|
| A list control must persist some values between posts to the server for this event to work correctly. Be sure that view state is enabled for the list control. |
Raising an event invokes the event handler through a delegate. For more information, see Consuming Events.
The OnSelectedIndexChanged 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 OnSelectedIndexChanged in a derived class, be sure to call the base class's OnSelectedIndexChanged method so that registered delegates receive the event.Community Additions
