Parameters
- sender
- A System.Object instance indicates the event source.
- e
- A System.EventArgs instance contains the event data.
The OnSpinDown 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 OnSpinDown in a derived class, be sure to call the base class's OnSpinDown method so that registered delegates receive the event.
