BaseDataList.OnSelectedIndexChanged(EventArgs) Method

Definition

Raises the SelectedIndexChanged event of a BaseDataList control.

C#
protected virtual void OnSelectedIndexChanged(EventArgs e);

Parameters

e
EventArgs

An EventArgs that contains the event data.

Remarks

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 Handling and Raising Events.

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(EventArgs) in a derived class, be sure to call the base class's OnSelectedIndexChanged(EventArgs) method so that registered delegates receive the event.
