GridView::OnSelectedIndexChanged Method (EventArgs^)
Raises the SelectedIndexChanged event.
Assembly: System.Web (in System.Web.dll)
The SelectedIndexChanged event is raised when a row's Select button is clicked, but after the 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.
Raising an event invokes the event handler through a delegate. For more information, see NIB: Raising an Event.
Themethod 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 overridingin a derived class, be sure to call the base class's method so that registered delegates receive the event.
The following example shows how create an event handler for the SelectedIndexChanged event. In this example, the selected row is persisted in the view state. So even after a sorting or a paging operation, only that row will be selected.
