SitefinitySiteMap and RadPanelbar issue with empty nodes - Sitefinity - Front- & Back-End Development

Hi all,

I've created a custom usercontrol for displaying a sidemenu.
I've used a SiteMapDataSource (based on the SitefinitySiteMap) and a default RadPanelbar.

When I don't have any subpages, it still renders 3 empty <li> tags. What are those things and how to get rid of them?

This is my code:

Subnavigation.ascx

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Subnavigation.ascx.cs"

Inherits="SitefinityWebApp.Custom.General.Subnavigation" %>

<%@ Register Assembly="Telerik.Sitefinity" Namespace="Telerik.Sitefinity.Web.UI"

TagPrefix="sf" %>

<telerik:RadPanelBar ID="sideNavigation" runat="server" EnableEmbeddedBaseStylesheet="false"

EnableEmbeddedSkins="false" DataSourceID="sfDatasource" Skin="EexSidebar">

</telerik:RadPanelBar>

<asp:SiteMapDataSource ID="sfDatasource" runat="server" SiteMapProvider="SitefinitySiteMap"

ShowStartingNode="false" StartFromCurrentNode="false" StartingNodeOffset="1" />

Subnavigation.ascx.cs

public partial class Subnavigation : System.Web.UI.UserControl

protected void Page_Load(object sender, EventArgs e)

this.sideNavigation.ItemDataBound += new RadPanelBarEventHandler(sideNavigation_ItemDataBound);

void sideNavigation_ItemDataBound(object sender, RadPanelBarEventArgs e)

var item = e.Item.DataItem as PageSiteNode;

if (!item.ShowInNavigation)

e.Item.Visible = false;

It renders the following output:

<div id="ctl00_ContentSidebar_T4181E1D7007_sideNavigation" class="RadPanelBar RadPanelBar_EexSidebar">

<ul class="rpRootGroup">

<li class="rpItem rpFirst"></li>

<li class="rpItem"></li>

<li class="rpItem rpLast"></li>

</ul>

</div>

But... there are no childnodes for the current page.

What is the problem here?

Regards,
Daniel

Try this instead

<sitefinity:SitefinitySiteMapDataSource ID="sfDatasource" runat="server" ShowStartingNode="false" />

And comment out all your code-behind databound code

It should have better performance and handle the Show In Navigation by itself.
