Panels never expanding on load/start

[Erik]

Hi,

I'm using the panelbar and whant the first panel to expand, on start.

This is my panel code:

<telerik:RadPanelBar ID="RadPanelBar_Portfolio" Width="100%" Height="100%" CssClass="masterPanelBar"
    ExpandMode="FullExpandedItem" runat="server" >
    <Items>
        <telerik:RadPanelItem Value="MainPanel" Selected="true" Expanded="True">
            <HeaderTemplate>
                <asp:label ID="Label8" Text="Portfolio" Font-Bold="true" runat="server" />
            </HeaderTemplate>
            <ContentTemplate>
                <table id="tbl_HeaderPortFolio" runat="server">
                    <tr>
....
                    </tr>
                </table>
            </ContentTemplate>
        </telerik:RadPanelItem>
    </Items>
</telerik:RadPanelBar>

The panel bar is inside a RadSplitter.
The radsplitter is inside a dynamically loaded control, that is in a RadAjaxPanel.

As you can see, I set Selected="true" Expanded="True" 
but that does not show the panel expanded. I always have to click the bar to see its content (the table)

I tried also to set it in code :

With RadPanelBar_Portfolio.FindItemByValue("MainPanel")
    .Expanded = True
    .Selected = True
    .Expanded = True
    .PreventCollapse = True
End With

and even in the PreRender (RadPanelBar_Portfolio.Items(0).Expanded = True)

and I tried setting it in JS:

function ExpandItem()
{
    var panelbar = <%= RadPanelBar_Portfolio.ClientID %>;
    var item = panelbar.FindItemByValue("MainPanel");
    if (item)
    {
        item.Expand();
    }
    else
    {
        //alert("Item with text 'MainPanel' not found.");
    }
}

ExpandItem;

But, no luck, the panelbar ALWAYS needs to be clicked first...

Please check screenshot for more details.

Could you tell me how I can see the first panel expanded?

Thanks

Erik

when I remove the <HeaderTemplate> it is no longer a problem?!

Hi Erik,

Indeed the behavior that you encounter is a bug of the RadPanelBar control when you use both HeaderTemplate and ContentTemplate that we are already aware of. It is already logged in our internal system and though I can not give you any specific timeframe we will do our best so that we can fix it shortly.
