Remarks

Raising an event invokes the event handler through a delegate.

The OnAttributeChanged 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 OnAttributeChanged(PropertyDataChangedEventArgs) in a derived class, call the OnAttributeChanged(PropertyDataChangedEventArgs) method for the base class to ensure that registered delegates receive the event.
