Occurs when a row's Select button is clicked, but after the System.Web.UI.WebControls.GridView control handles the select operation.
The GridView.SelectedIndexChanged event is raised when a row's Select button is clicked, but after the System.Web.UI.WebControls.GridView control handles the select operation. This enables you to provide an event-handling method that performs a custom routine, such as updating a status label with the currently selected row, whenever this event occurs.
