1.函数(参考其它网友，有作变动)

#Region "防止页面滚动"
    Private Function RetainScrollPosition()
        Dim saveScrollPosition As StringBuilder = New StringBuilder
        Dim setScrollPosition As StringBuilder = New StringBuilder

RegisterHiddenField("__SCROLLPOS", "0")

        saveScrollPosition.Append("<script language='javascript'>")
        saveScrollPosition.Append("function saveScrollPosition() {")
        saveScrollPosition.Append("    document.forms[0].__SCROLLPOS.value = mybody.scrollTop;")
        saveScrollPosition.Append("}")
        saveScrollPosition.Append("mybody.onscroll=saveScrollPosition;")
        saveScrollPosition.Append("</script>")

RegisterStartupScript("saveScroll", saveScrollPosition.ToString())

        If (Page.IsPostBack) Then
            setScrollPosition.Append("<script language='javascript'>")
            setScrollPosition.Append("function setScrollPosition() {")
            setScrollPosition.Append("    mybody.scrollTop = " & Request("__SCROLLPOS") & ";")
            setScrollPosition.Append("}")
            setScrollPosition.Append("mybody.onload=setScrollPosition;")
            setScrollPosition.Append("</script>")

            RegisterStartupScript("setScroll", setScrollPosition.ToString())
        End If
    End Function
#End Region

2.调用

在page_load事件中调用RetainScrollPosition()

3.其它

将<body>的id命名为“mybody”
