BaseDataList.OnSelectedIndexChanged Method

Raises the SelectedIndexChanged event of a BaseDataList control.

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

protected virtual void OnSelectedIndexChanged(
	EventArgs e
)

Parameters

e
Type: System.EventArgs

An EventArgs that contains the event data.

The SelectedIndexChanged event is raised when a different item is selected in a data listing control between posts to the server. The OnSelectedIndexChanged method allows you to create a custom handler for the event.

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.
