Raising an event invokes the event handler through a delegate. The OnUndoRedoChanged 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.
The UndoRedoChanged event will be fired when the undo/redo buffer changes. This gives the application a chance to update the user interface if needed.
The undo/redo buffer changes whenever an object inside the Container changes either by user interaction through the user interface or by code.
