I wrote below code for Collapse/Expand some section. It is working fine. Finally If I click "Save" button and I am re-loading page again in asp.net. So then sections are going default Colleapse again. I need them back to expand. How can I do that?

$(function() {
       $('tr.subCategory')
           .css("cursor", "pointer")
           .attr("title", "Click to expand/collapse")
           .click(function() {
       $(this).siblings('.RegText-' + this.id).toggle();
           });
           $('tr[@class^=RegText-]').hide().children('td');
   })
