RadPanelBar into RadPanelBar

[Vincent]

Hi,

I try to use RadPanelBar into an other RadPanelBar and I have a problem with the level2 RadPanelBar.
This is my code :

<telerik:RadPanelBar ID="RadPanelBar1" runat="server" Width="100%">
            <Items>
                <telerik:RadPanelItem Text="PanelItem1">
                    <ContentTemplate>
                        <telerik:RadPanelBar ID="PanelBar2" runat="server" Width="100%">
                            <Items>
                                <telerik:RadPanelItem Text="Title1">
                                    <HeaderTemplate><table style="width:100%;"><tr><td>Title1</td><td style="text-align:right;"><asp:ImageButton ID="ImgBtnRemoveContact1" runat="server" ImageUrl="~/images/cancel.png" /></td></tr></table></HeaderTemplate>
                                    <ContentTemplate>

                                </telerik:RadPanelItem>
                            </Items>
                        </telerik:RadPanelBar>
                    </ContentTemplate>
                </telerik:RadPanelItem>
            </Items>
        </telerik:RadPanelBar>

With this code, I can't expand the level 2 RadPanelItem (or it expand but I can't see the content)
Is it possible to solve this ?

Sorry for my poor english.

After some research, I solve my problem using Hierarchical PanelBar insted of PanelBar in PanelBar
