       CancelEventArgs e
    )

    Parameters

    e
    A System.ComponentModel.CancelEventArgs that contains the event data.
    Remarks
    Raising an event invokes the event handler through a delegate.

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