  Accordion Control in MasterPage does not remember its SelectedIndex

  Feb 21, 2009 12:37 PM|LINK

  Hey guys, I hope anybody out there could help me!

  I've been Googling for so long now and I cannot find a straight answer or correct solution to my problem (especially when I'm a novice at JavaScript/C#!).

  I have got an Accordion Control on my MasterPage which acts as a menu. My problem is that when I click on a button within the content pane it displays a new page within the ContentPlaceHolder, but the Accordion resets itself back to SelectedIndex = 0. How can I keep the SelectedIndex = 1 open when I'm response.redirected to another page?

  I have heard about sessions but I can't make any sense of them. Any suggestions or solutions would be great!

  Many thanks.

  If you do a Response.Redirect the asp request page as a new request to the server. The drop down list selected index as stored in viewstate.Since the request is new request to the server there will not be any viewstate information for the new page.

  Hi,

  When you response.redirect to another page, you can pass parameter via Session.

  page1.aspx: 

  protected void Button1_Click(object sender, EventArgs e)
          {
              Session["selectedIndex"] = "1";
          }

   Page2.aspx: 

  protected void Page_Load(object sender, EventArgs e)
          {
              if (!IsPostBack)
              {
                  if (Session["selectedIndex"] != null)
                  {
                      int selectedIndex=int.Parse(Session["selectedIndex"].ToString());
                  }
              }
          }

  Hi,

  I also used the Accordion control as a menu on the master page and faced the same problem.

  Here is the solution.

  On the Page_Load event of ur aspx page containing the content pane, write down the following code

  using System;
  using AjaxControlToolkit;
  
  protected void Page_Load(object sender, EventArgs e)
  {
     Accordion accordioMenu = (Accordion) Master.FindControl("AccordionMenu");
     accordioMenu.SelectedIndex = 2;
  }

  Please first add the namspace of Ajax Control Toolkit in ur code behind file so that u can create an accordion objec in the codet . In page load event find the accordion control on the master page by using this method : Master.FindControl("Id of ur accordion control") . Don't forget to type cast it. Then set the index. Thus while loading this page menu will show the appropriate accordion pane open.

  Please feel free to ask any doubt.

  Please mark it as answer if found useful

  Yep already have!

  But now I have a different problem, still relating to the Accordion control. Now that I have the SelectedIndex working, I'm stuck on how to change the button to a different colour...

  Here's the background: Myself and my fiancee have started up an online pet store and when a user clicks on 'For Kittens & Cats' the content pane appears with sub-category buttons. Now when a user then clicks on a sub-category I want this image to change to a selected image on the relevant page. At the moment I am using a and a:active in the CSS to change this but am stuck because when it does change page this button is no longer selected.

  If you have no idea what I've just said, please visit my very unfinished website at www.touchofglitz.co.uk and click on 'For Kittens & Cats' and then 'ID Tags'.

  Please help me! Many thanks once again.

  Hey

  The ones I am talking about are in the Accordion control on the left hand side. When the user clicks 'For Kittens & Cats', the content pane appears with the unselected light purple button 'ID Tags'. Now when the user clicks on 'ID Tags' and is redirected to the ID Tags page, I want to be able to change the 'ID Tags' button image so that it changes colour to dark purple (the same way as the 'For Kittens & Cats' button is unselected and then selected).

  For the 'ID Tags' button I am using CSS 'a' hyperlink tag and a:active as well to change from one image to another. This works fine BUT it needs to keep to the a:active image on the selected page to basically let the user know what they selected and where they are.

  Hope this helps!

  Hi friend!

  Replying u so late [:$] was busy with my work!

  In the same way, in the page load event of the Id tags page , find the "ID tags" button control. and set its background image there. Thus when the ID tags page will be displayed ur button will look as selected.

  Hope this will help u.

  Please feel free to ask any doubt
