The GridView control raises the SelectedIndexChanging event when a Select button (a button with its CommandName property set to "Select") is clicked, but before the GridView control handles the select operation. This allows you to provide an event-handling method that performs a custom routine, such as canceling the selection operation, whenever this event occurs.
A object is passed to the event-handling method, which allows you to determine the index of the row selected by the user and to indicate that the selection operation should be canceled. To cancel the selection operation, set the Cancel property of the object to true.
