Expanding Problem in Firefox 4

[Mehmet]

Hello,

When I am using RadPanelbar all expanding and collapsing functions work well in IE and/or Chrome. But when I try it in Firefox 4 no expanding or collapsing occur. Here is my code :

   <telerik:RadPanelBar ID="RadPanelBar1" runat="server" EnableEmbeddedSkins="false"
                Height="100%" ExpandMode="SingleExpandedItem" Skin="ShowCategory" Width="100%"
                AllowCollapseAllItems="false" OnClientItemClicking="OnClientItemClicking">
            </telerik:RadPanelBar>

I am programmatically creating the items. 

One more thing, in all other browser I can call OnClientItemClicking event but in FireFox 4.0 its not firing. FYI, added script below :

 <script type="text/jscript">
        function OnClientItemClicking(sender, args) {
            debugger;
            if (args.get_item().get_level() == 0) {
                args.set_cancel(true);
               args.get_item().set_expanded(!args.get_item().get_expanded());
            }
       }            
    </script>

I am using Telerik  2010.1.519.35.

What can cause that problem? Any Idea?

Hi Mehmet,

I would suggest that you open FireBug and check for any javascript errors on the page.
That could be the reason for this unexpected behavior.
Just for the test - what happens if you use the default built-in skin instead of the custom one?
