Set jQuery Toggle to be open on ASP.Net Gridview Postback

I have a jQuery 'toggle' function on a table that I am using in conjunction with an asp.net gridview. I have pagination on my gridview and when I click on the next page, it posts back and therefore closes the Toggle/Table - I need a way of keeping it open. I have had a similar issue in the past with the Accordion function but resolved it via this method and wondered if one of you jQuery/Javascript geniuses could help:

<asp:HiddenField ID="hidAccordionIndex" runat="server" Value="0" />
    <script language="javascript" type="text/javascript">
        $(function () {
            var activeIndex = parseInt($('#<%=hidAccordionIndex.ClientID %>').val());

            $("#accordion").accordion({
                autoHeight: false,
                event: "mousedown",
                active: activeIndex,
                change: function (event, ui) {
                    var index = $(this).children('h3').index(ui.newHeader);
                    $('#<%=hidAccordionIndex.ClientID %>').val(index);
                }
            });
        });
    </script>
    <div id="accordion">
        <h3><a href="#">Table Header 1 here</a></h3>
        <div>
            Some text here
        </div>
        <h3><a href="#">Table Header 2 here</a></h3>
        <div>

Here is my current code that I have the issue with:

<div class="box grid_16 round_all">
                    <h2 class="box_head grad_colour round_top">Client List</h2> 
                    <a href="#" class="toggle toggle_closed">&nbsp;</a>
                    <div class="toggle_container" style="display:none;">
                        <asp:Label ID="LBLMessage" runat="server" />
                                <asp:GridView ID="gvClients" runat="server" CssClass="static" AutoGenerateColum开发者_StackOverflow中文版ns="true" AllowPaging="true" Visible="true" />
                    </div>
            </div>

and here is the jQuery:

// Content Box Toggle Config 
        $("a.toggle").click(function(){
            $(this).toggleClass("toggle_closed").next().slideToggle("slow");
            return false; //Prevent the browser jump to the link anchor
        });

Thanks in advance!

Try this:

$(function () {
            $("a.toggle").click(function () {
                $(this).toggleClass("toggle_closed").next().slideToggle("slow", function () {
                    if($(this).is(':visible')){
                    $('#<%=hidAccordionIndex.ClientID %>').val("1");
                    }
                    else{
                    $('#<%=hidAccordionIndex.ClientID %>').val("0");
                    }
                });
                return false; //Prevent the browser jump to the link anchor
            });
            var val = $('#<%=hidAccordionIndex.ClientID %>').val();
            if (val == "1") {
                $("a.toggle").click();
            }
        });

<asp:HiddenField ID="hidAccordionIndex" runat="server" Value="0" />

Update 1: Check this test page. GV paging isn't functional but it does simulate the scenario. Let me know in terms of this example how it differs from what you are expecting. Wondering if you want to use UpdatePanel and see if that helps.
