        var activeIndex = parseInt($('#<%=hidAccordionIndex.ClientID %>').val());       

        $("#accordion,#inneraccordian").accordion({
            heightStyle: "content",
            collapsible: true,
            navigation: true,
            active: activeIndex,
            beforeActivate: function (event, ui) {
                var index = $(this).children('h3').index(ui.newHeader);
                $('#<%=hidAccordionIndex.ClientID %>').val(index);
            }
        });
