ComboBox.OnSelectedIndexChanged Method

Raises the SelectedIndexChanged event.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

protected override void OnSelectedIndexChanged (
	EventArgs e
)
protected void OnSelectedIndexChanged (
	EventArgs e
)
protected override function OnSelectedIndexChanged (
	e : EventArgs
)
Not applicable.

Parameters

e

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 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.
