    ) 
    'Usage
     
    
    Dim instance As GcNumber
    Dim e As PopUpOpeningEventArgs
     
    instance.OnPopUpOpening(e)
    protected virtual void OnPopUpOpening( 
       PopUpOpeningEventArgs e
    )

    Parameters

    e
    A PopUpOpeningEventArgs instance contains the event data.
    Remarks
    Raising an event invokes the event handler through a delegate.

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