    Remarks
    Raising an event invokes the event handler through a delegate.

    The OnInvalidInput 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 OnInvalidInput in a derived class, be sure to call the base class's OnInvalidInput method so that registered delegates receive the event.
