UserControl事件觸發然後執行父網頁事件

UserControl 中宣告  
Public Delegate Sub Parent_EventHandler(ByVal sender As Object, ByVal e As System.EventArgs)
Public Event UsercontrolSelectEvent As Parent_EventHandler
然後在要觸發的事件中宣告
EX:

Protected Sub DropDownList名稱 _SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles DropDownList名稱.SelectedIndexChanged
        RaiseEvent UsercontrolSelectEvent(sender, e)
End Sub

在使用UserControl 的VB中
Page_Load裡宣告
AddHandler Me.UserControl名稱.UsercontrolSelectEvent, AddressOf  UsercontrolSelectEvent_proc
然後事件即可使用
Private Sub UsercontrolSelectEvent_proc(ByVal sender As Object, ByVal e As System.EventArgs)


 End Sub
