Raises the ValueChanged routed event.
Assembly: PresentationFramework (in PresentationFramework.dll)
Subclasses of the RangeBase can use this method to respond when the value property changes instead of overriding the FrameworkPropertyMetadata to provide a new PropertyChangedCallback function. For more information, see Dependency Property Callbacks and Validation.
The method raises the ValueChanged event. When overriding in a derived class, be sure to call the base class’s method so that registered delegates receive the event.
