RadPanelBar not expanding

[Jeremy]

I am using RadPanelBar throughout my site and it works fine.  But suddenly when I try to add another one on a user control, I get some weird behavior.  The expandmode I'm using on the site is MultipleExpandedItems and that's what I would like to use in this user control.  I've spent hours on this and have tried to approach it from different directions.  I'm finally at the point where I copied the demo from Telerik and still getting the weird results.  Here's my current test user control.

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="TestUserControl.ascx.cs" Inherits="UserControls.TestUserControl" %>
     <div>
        <telerik:RadPanelBar runat="server" ID="RadPanelBar1" ExpandMode="MultipleExpandedItems">
            <Items>
                <telerik:RadPanelItem Text="Panel 1">
                    <Items>
                        <telerik:RadPanelItem Text="Item 1" />
                        <telerik:RadPanelItem Text="Item 2" />
                        <telerik:RadPanelItem Text="Item 3" />
                    </Items>
                </telerik:RadPanelItem>
                <telerik:RadPanelItem Text="Panel 2">
                    <Items>
                        <telerik:RadPanelItem Text="Item 4" />
                        <telerik:RadPanelItem Text="Item 5" />
                        <telerik:RadPanelItem Text="Item 6" />
                    </Items>
                </telerik:RadPanelItem>
            </Items>
        </telerik:RadPanelBar>
    </div>

The panels render as collapsed and when you click on them nothing happens.  However, when I change the ExpandMode to SingleExpandedItem then suddenly it works.  Why does it only work on SingleExpandedItem mode in my user control but not in MultipleExpandedItems mode?  And why does MultipleExpandedItems work everywhere else on my site?

Hello Jeremy,

I replied to your inquiry in the other thread with identical subject in the Ticketing System. I suggest we continue the discussion in it, in order to avoid thread duplication.

Dear Ivan,

Please provide a link to your answer

 

Thanks

Hello Ehab,

I attached a sample project that followed Jeremy's scenario. He was not able to reproduce in the sample project the issue with the items not expanding when MultipleExpandedItems mode is set. We were not able to reproduce any issue either. Eventually he decided to go with a different approach.

However, this does not work if you are using code behind onItemClick event

Hi Henry, 

Can you elaborate a bit on the exact logic that you have implemented in the OnItemClick event handler and the functionality that fails to work? Can you send me a small project demonstrating that?
