Control.OnRegionChanged Method (EventArgs)


Raises the RegionChanged event.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

protected virtual void OnRegionChanged(
	EventArgs e


Type: System.EventArgs

An EventArgs that contains the event data.

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

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