前端:

<script type="text/javascript">
  window.onload = function (){var h = document.getElementById("<%=hfScrollPosition.ClientID%>");
               document.getElementById("<%=scrollArea.ClientID%>").scrollTop = h.value;}
   function SetDivPosition(){var intY = document.getElementById("<%=scrollArea.ClientID%>").scrollTop;var h = document.getElementById("<%=hfScrollPosition.ClientID%>");
           h.value = intY;}

  function afterpostback(){var h = document.getElementById("<%=hfScrollPosition.ClientID%>");
            document.getElementById("<%=scrollArea.ClientID%>").scrollTop = h.value;}</script><asp:HiddenField ID="hfScrollPosition" runat="server"Value="0"/><div id="scrollArea" onscroll="SetDivPosition()"   runat="server"  style="height:225px;overflow:auto;overflow-x:hidden;">

後端:

if(Page.IsPostBack){ScriptManager.RegisterClientScriptBlock(Page,this.GetType(),"CallJS","afterpostback();",true);}
