The PageIndexChanging event is raised when one of the pager buttons is clicked, but before the GridView control handles the paging operation. This enables you to provide an event-handling method that performs a custom routine, such as canceling the paging operation, whenever this event occurs.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The OnPageIndexChanging 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 OnPageIndexChanging in a derived class, be sure to call the base class's OnPageIndexChanging method so that registered delegates receive the event.
