GridView.OnSelectedIndexChanging Method

Raises the SelectedIndexChanging event.

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

protected virtual void OnSelectedIndexChanging (
	GridViewSelectEventArgs e
)
protected void OnSelectedIndexChanging (
	GridViewSelectEventArgs e
)
protected function OnSelectedIndexChanging (
	e : GridViewSelectEventArgs
)
Not applicable.

Parameters

e

A GridViewSelectEventArgs that contains event data.

The SelectedIndexChanging event is raised when a row's Select button 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.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The OnSelectedIndexChanging 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 OnSelectedIndexChanging in a derived class, be sure to call the base class's OnSelectedIndexChanging method so that registered delegates receive the event.
