Custom widget throwing js error

Hello,
I have created a custom widget for a side navigation that loads pages from a RadSiteMapDataSource  .
The control loads and works apparently fine, but firebug shows a js error : f is not a costructor in Telerik.Web.UI.WebResource.axd line 20 and when i add another control on the same page, the new added control doesn't work when I click any tab .
The strange thing is that when I add another custom radpanelbar on the page all controls work .

This is the control that throws the error

SubNavigation.ascx

01.<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="SubNavigation.ascx.cs"
02.    Inherits="SitefinityWebApp.UserControls.SubNavigation" %>
03.     
04.<telerik:RadPanelBar runat="server" ID="RadPanelBar1" 
05.     
06. DataSourceID="RadSiteMapDataSource2" ExpandMode="SingleExpandedItem" CssClass="subNav"
07.    onitemdatabound="RadPanelBar1_ItemDataBound"  >
08.    
09.    </telerik:RadPanelBar>
10.<telerik:RadSiteMapDataSource ID="RadSiteMapDataSource2" runat="server" StartingNodeUrl="~/products"
11.    ShowStartingNode="false"  />
Subnavigation.ascx.cs
01.    public partial class SubNavigation : System.Web.UI.UserControl
02.    
03.        public String StartNode get; set;  
04.        
05.        protected void Page_Load(object sender, System.EventArgs e)
06.        
07.            
08.            if (!StartNode.IsNullOrEmpty())
09.            
10.                //SiteMapNode startNode =SiteMapBase.GetCurrentProvider().Fin
11.                RadSiteMapDataSource2.StartingNodeUrl = "~/" + StartNode;
12.                 
13.       
14.        protected void RadPanelBar1_ItemDataBound(object sender, RadPanelBarEventArgs e)
15.        
16.            SiteMapNode currentNode = SiteMapBase.GetCurrentProvider().CurrentNode;
17.            RadPanelItem it = e.Item;
18.             
19.            if (it.Text.ToLower().Equals(currentNode.Title.ToLower()))
20.            
21.                e.Item.ExpandParentItems();
22.                e.Item.CssClass = " rpExpanded";
23.                e.Item.SelectedCssClass = " rpExpanded";
24.                e.Item.ExpandedCssClass = " rpExpanded";              
25.            
26.      
27.    

This is the template of the second control  PDet.ascx
01.<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Pdet.ascx.cs" Inherits="SitefinityWebApp.UserControls.Pdet" %>
02.<div class="tabsHolder">
03.    <telerik:RadTabStrip runat="server" ID="RadTabStrip1" Orientation="HorizontalTop"
04.        CssClass="tabsMenu" Skin="Athena" EnableEmbeddedSkins="false" SelectedIndex="0"
05.        MultiPageID="RadMultiPage1">
06.    </telerik:RadTabStrip>
07.    <telerik:RadMultiPage runat="server" ID="RadMultiPage1" SelectedIndex="0" CssClass="tabsPanes">
08.    </telerik:RadMultiPage>
09.</div>

PDet.ascx.cs

01.public partial class Pdet : System.Web.UI.UserControl
02.    
03.        public String ProductList get; set;
04. 
05.        protected void Page_Load(object sender, EventArgs e)
06.        
07.            if (ProductList.IsNullOrEmpty())
08.            
09.                ProductList = this.Page.Title;
10.            
11.            else
12.            
13.                var lists = App.WorkWith().Lists().Get().Where(li => li.Title.Equals(ProductList)).First();
14.                int i = 1;
15.                foreach (var listItem in ((Telerik.Sitefinity.Lists.Model.List)lists).ListItems.Distinct())
16.                
17.                    if (RadTabStrip1.Tabs.FindTabByText(listItem.Title.ToString()) == null)
18.                    
19.                        RadTab tab = new RadTab();
20.                        tab.Text = listItem.Title;
21.                        //tab.Text = listItem.Title + " " + RadTabStripTab.Tabs.Count;
22.                        RadTabStrip1.Tabs.Add(tab);
23.                        Literal listContent = new Literal();
24.                        listContent.Text = listItem.Content;
25. 
26. 
27.                        RadPageView page = new RadPageView();
28.                        page.CssClass = "tabPane";
29.                        page.ID = "RadPageView" + i++;
30.                        page.Controls.Add(listContent);
31.                        RadMultiPage1.PageViews.Add(page);

Hi Tudor,

I can`t get your controls to work. I made small changes to them as described in documentation . And all worked fine. Tell me if this changes suit your purpose.
Modified your .ascx file like:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="SubNavigation.ascx.cs" Inherits="SitefinityWebApp.SubNavigation.SubNavigation" %>
<%@ Register TagPrefix="sf" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>
<asp:SiteMapDataSource ID="RadSiteMapDataSource2" runat="server" />
 
 
<sf:RadPanelBar runat="server" ID="RadPanelBar1" 
 DataSourceID="RadSiteMapDataSource2" ExpandMode="SingleExpandedItem" CssClass="subNav"
    onitemdatabound="RadPanelBar1_ItemDataBound"  > 
   </sf:RadPanelBar>

Please write back if you experience other problems.

Kind regards,
