Remarks
Raising an event invokes the event handler through a delegate.
The OnPropertyDataChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event.
Notes to Inheritors
When overriding OnPropertyDataChanged(PropertyDataChangedEventArgs) in a derived class, call the OnPropertyDataChanged(PropertyDataChangedEventArgs) method for the base class to ensure registered delegates receive the event.
