如果继承自定义控件里的event

在User Control里写Calendar，给自定义控件加一个事件（SelectionChanged），相应控件里Canlendar的 SelectionChanged 事件 

Public   Delegate   Sub   SelectionChangedHandler(ByVal   sender   As   Object,   ByVal   e   As   System.EventArgs)

Partial   Class   UserControls_WebUserControl
        Public   Event   SelectionChanged   As   SelectionChangedHandler

        Protected   Sub   Calendar1_SelectionChanged(ByVal   sender   As   Object,   ByVal   e   As   System.EventArgs)   Handles   Calendar1.SelectionChanged
                RaiseEvent   SelectionChanged(sender,   e)
        End   Sub
End   Class
