ASP.NET Maintain scroll position after postback in div inside data list and user control

Question

My situation looks like this: I've got x-axis scrollable div that contains buttons with numbers of page displayed. This div is placed in data list inside User Control responsible for displaying news on my site.

This is the code of this div and datalist with page numbers.

<div style="width:430px; overflow:auto; overflow-y:hidden; -ms-overflow-y:hidden; vertical-align:top; position:relative; top:-1px; ">
            <asp:DataList ID="dlPaging" runat="server" OnItemCommand="dlPaging_ItemCommand" RepeatDirection="Horizontal" 
                OnItemDataBound="dlPaging_ItemDataBound">
                <ItemTemplate>
                    <asp:Button ID="lnkbtnPaging" class="pagebutton" runat="server" CommandArgument='<%# Eval("PageIndex") %>'
                        CommandName="lnkbtnPaging" Text='<%# Eval("PageText") %>' CausesValidation="False" />
                </ItemTemplate>
            </asp:DataList>
            </div>

How to mantain x-axis position of this div after postback? I've tried several tricks, javascript and I can't figure it out.

Any reason not to use an UpdatePanel?

                            </asp:DataList>
                        </div>    
<asp:HiddenField id="hdnScrollPos" runat="server"/>

            <script type="text/javascript">
                function BeginRequestHandler(sender, args)
                {
                    document.getElementById('<%=hdnScrollPos.ClientID %>').value = document.getElementById('<%=divDtPaging.ClientID %>').scrollLeft;
                }
                function EndRequestHandler(sender, args) {
                    document.getElementById('<%=divDtPaging.ClientID %>').scrollLeft = document.getElementById('<%=hdnScrollPos.ClientID %>').value;
                }

                if (window.Sys && Sys.WebForms && Sys.WebForms.PageRequestManager) {
                    var prm = Sys.WebForms.PageRequestManager.getInstance()
                    prm.add_beginRequest(BeginRequestHandler);
                    prm.add_endRequest(EndRequestHandler);
                }

        </script>
