Question

<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="Server">
    <meta http-equiv="refresh" content="4" />   
 <script type="text/javascript">

    var xPos1, yPos1;

    var prm = Sys.WebForms.PageRequestManager.getInstance();
    prm.add_pageLoading(pageLoadingHandler);
    prm.add_pageLoaded(pageLoaded);
    function pageLoaded(sender, args) {

        $get('<%=Panel_Users.ClientID %>').scrollLeft = xPos1;
        $get('<%=Panel_Users.ClientID %>').scrollTop = yPos1;
    }
    function pageLoadingHandler(sender, args) {
        xPos1 = $get('<%=Panel_Users.ClientID %>').scrollLeft
        yPos1 = $get('<%=Panel_Users.ClientID %>').scrollTop;
    }
    </script>
</asp:Content>

Doesn’t work, where am I going wrong

    <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true"  />    

<div style="height: 504px; width: 941px;">

             </div>

I am trying to make the page stay at the same position when the page refreshes after every 5 seconds and the page goes to top. I tried Page MaintainScrollPositionOnPostback=”true” . It didn’t work, I tried using Ajax but have no idea how to use it. Can someone help me how to do it with Ajax.

Answer 1

The MaintainScrollPositionOnPostback only works in IE. To do this you can either roll your own client script or use anchor links on different sections of your page/form.
