ComboBox.OnSelectedIndexChanged(EventArgs) Method


Raises the SelectedIndexChanged event.

 override void OnSelectedIndexChanged(EventArgs ^ e);
protected override void OnSelectedIndexChanged (EventArgs e);
override this.OnSelectedIndexChanged : EventArgs -> unit
Protected Overrides Sub OnSelectedIndexChanged (e As EventArgs)



An EventArgs that contains the event data.


This event is raised when you select a new item from the list or when you set the SelectedIndex property.

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.
