The GridView.PageIndexChanging event is raised when one of the pager buttons is clicked, but before the System.Web.UI.WebControls.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 GridView.OnPageIndexChanging(GridViewPageEventArgs) 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.
