Raises the SelectedIndexChanged event.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
The SelectedIndexChanged event is raised when an item's Select button is clicked, after the ListView control handles the select operation. (A Select button is a button control whose CommandName property is set to "Select".) This enables you to perform a custom routine whenever this event occurs, such as updating a status label with the currently selected item.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The method also enables 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 you override in a derived class, call the base class's method so that registered delegates receive the event.
