Parameters

Remarks

Subclasses of the RangeBase can use this method to respond when the value property changes.

The OnValueChanged method raises the ValueChanged event. When overriding OnValueChanged in a derived class, make sure to call the base class’s OnValueChanged method so that registered delegates receive the event.
