Form.OnBackgroundImageChanged(EventArgs) Method

Definition

Raises the BackgroundImageChanged event.

C#
protected override void OnBackgroundImageChanged(EventArgs e);

Parameters

e
EventArgs

An EventArgs that contains the data.

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

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