GridView.OnSelectedIndexChanged Method

Raises the SelectedIndexChanged event.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

abstract OnSelectedIndexChanged : 
        e:EventArgs -> unit 
override OnSelectedIndexChanged : 
        e:EventArgs -> unit 

Parameters

e
Type: System.EventArgs
An System.EventArgs that contains event data.

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 Raising an Event.

The OnSelectedIndexChanged 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 OnSelectedIndexChanged in a derived class, be sure to call the base class's OnSelectedIndexChanged 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.

No code example is currently available or this language may not be supported.
