On Size Changed(EventArgs) Method

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnSizeChanged method also enables derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
