Remarks
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 OnValueChanged method raises the ValueChanged event. When overriding OnValueChanged in a derived class, be sure to call the base class' OnValueChanged method so that registered delegates receive the event.
