Control::OnRegionChanged Method (EventArgs^)

.NET Framework (current version)

Other Versions

Raises the RegionChanged event.

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

Syntax

C++

protected:
virtual void OnRegionChanged(
	EventArgs^ e
)

Parameters

e: Type: System::EventArgs^
An EventArgs that contains the event data.

Remarks

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.
