    A DropDownClosingEventArgs instance contains the event data.
    Raising an event invokes the event handler through a delegate.

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