ListControl::OnSelectedIndexChanged Method (EventArgs^)
Raises the SelectedIndexChanged event. This allows you to provide a custom handler for the event.
Assembly: System.Web (in System.Web.dll)
Parameters
- e
-
Type:
System::EventArgs^
A System::EventArgs that contains the event data.
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 NIB: 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.
The following example demonstrates how to specify and code a handler for the SelectedIndexChanged event to display the selection made by the user.
