problem updating data with collapsible panels

problem updating data with collapsible panels

I am encountering an issue with my accordion control (using jQuery) on the page. It seems that when I insert the contents of my page into an updatepanel, the accordion stops working. However, if I remove the updatepanel, it starts working again.

I'm trying to understand why this is happening and how I can fix this error. Do I need to re-instantiate the accordion script/plugin? If so, how should I go about doing that?

  <script src="Scripts/ddaccordion.js" type="text/javascript"></script>
<script type="text/javascript">
   ddaccordion.init({
        headerclass: "silverheader", 
        contentclass: "submenu", 
        revealtype: "mouseover", 
        mouseoverdelay: 200, 
        collapseprev: true, 
        defaultexpanded: [0], 
        onemustopen: true, 
        animatedefault: false, 
        persiststate: true, 
        toggleclass: ["", "selected"], 
        togglehtml: ["", "", ""],
        animatespeed: "fast",
        oninit: function(headers, expandedindices) { 
            //do nothing
        },
        onopenclose: function(header, index, state, isuseractivated) { 
            //do nothing
        }
    })
</script>

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
      <div class="applemenu">
        <div class="silverheader"><a href="http://www.dynamicdrive.com">Dynamic Drive</a></div>
        <div class="submenu">

Make sure to utilize pageLoad, as it is triggered during all partial postbacks:

 <script type="text/javascript>
    function pageLoad()
    {
       ddaccordion.init({
            headerclass: "silverheader", //CSS class name for headers group
            contentclass: "submenu", //CSS class name for contents group
            revealtype: "mouseover", //How should the content be revealed? Options: "click", "clickgo", or "mouseover"
            mouseoverdelay: 200, //Delay in milliseconds before header expands onMouseover (for revealtype="mouseover")
            collapseprev: true, //Should previous content collapse when new one opens? true/false
            defaultexpanded: [0], //Index of content(s) open by default [index1, index2, etc] [] means no default content
            onemustopen: true, //At least one header must always be open
            animatedefault: false, //Should default open contents be animated?
            persiststate: true, //Persist state of opened contents within browser session?
            toggleclass: ["", "selected"], //Two CSS classes for collapsed and expanded states of header
            togglehtml: ["", "", ""], //Additional HTML added to header when collapsed and expanded
            animatespeed: "fast", //Animation speed: integer in milliseconds (e.g., 200) or keywords "fast", "normal", or "slow"
            oninit: function(headers, expandedindices) { //Custom code to run when headers are initialized
                //do nothing

To ensure that all content is within the update panel, be sure to integrate your script into the update panel for optimal functionality.

When your accordion's content and definition are enclosed within an update panel, you'll need to reinitialize it every time the panel updates. This is because each update essentially provides a fresh copy of the accordion, causing any associated events to be lost.

We faced a similar issue with various controls and found a workaround by placing only essential elements inside the update panel, such as hidden buttons. Then, we programmed the accordion to trigger these buttons to ensure that the update panel functions correctly without affecting the accordion.

Although this post is dated, the problem remains unresolved.

There are two main issues at play here:

The first issue, as highlighted by @rickschott, is the need to initialize the plugin after each partial reload of the page (not just the initial load). This is because the plugin resides within an UpdatePanel and will cease to function correctly after a reload of the UpdatePanel.

Once you address that issue, you may encounter a second problem: it appears that the page keeps refreshing indefinitely without fully loading. This could be attributed to a bug in the ddaccordion jQuery plugin, which seems incapable of being reset or recreated without reloading the entire page. I devised a workaround, but it may require testing on your end:

Open ddaccordion.js and locate init:function(config).
Delete the following four lines:

document.write('<style type="text/css>\n')
document.write('.'+config.contentclass+'{display: none}\n') //generate CSS to hide contents
document.write('a.hiddenajaxlink{display: none}\n') //CSS class to hide ajax link
document.write('</style>')

This modification should resolve the issue. Remember to add those 2 CSS classes to your stylesheet:

.submenu { display:none }
a.hiddenajaxlink { display:none }

Important: It's generally not advisable to alter third-party plugins because any updates might overwrite your changes. However, given that ddaccordion appears to be abandoned by its creators, this workaround could serve as a viable solution for others facing similar issues.
