从Shared Sub中强制UpdatePanel.Update（）

Question

有没有办法在UpdatePanel1.Update()内执行Shared Sub？

收到错误：Cannot refer to an instance member of a class from within a shared sub ..

<WebMethod()> _
Public Shared Sub DoSomeStuff(ByVal Param1 As String)

    // do some stuff and then update the updatepanel
    UpdatePanel1.Update() // not a valid code


End Sub

任何建议都非常感谢。
