    'Usage
     
    
    Dim instance As GcComboBox
    Dim sender As Object
    Dim e As EventArgs
     
    instance.OnSpinDown(sender, e)
    protected virtual void OnSpinDown( 
       object sender,
       EventArgs e
    )

    Parameters

    sender
    A System.Object instance indicates the event source.
    e
    A System.EventArgs instance contains the event data.
    Remarks
    Raising an event invokes the event handler through a delegate.

    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.
