Remarks

Raising an event invokes the event handler through a delegate.

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

Requirements
