WMS not in Map-Contents

[elk2210]

Hi experts,

I've got a problem with ArcGIS for Sharepoint and the Add-WMS-Plugin from the SDK.
The plugin ist working and the WMS-layer I want to add is displayed over my base-map. Fine.

But the layer is not displayed (or not added) to the "Map-Contents"-section and so it's hard to work with this layer.

I have no clue were the problem is, but I think it must be in WMSCommand.xaml.cs.
I've done some little changes to this file, because my WMS-server does not match the name-schema from the example (not the same ending of the link) and my code looks no like this:

using System;
using System.Collections.Generic;
using System.Windows;
using System.Windows.Controls;
using ESRI.ArcGIS.Client.Extensibility;
using ESRI.ArcGIS.Client.Toolkit.DataSources;

namespace WMSCommand
{
    public partial class WMSDialog : UserControl
    {
        public WMSDialog()
        {
            InitializeComponent();
        }

        private WmsLayer wmsLayer;
        private void Add_Click(object sender, RoutedEventArgs e)
        {
            wmsLayer = new WmsLayer();
            wmsLayer.Url = ((ComboBoxItem)this.WMSList.SelectedItem).Tag.ToString(); 
            
            // Copy the ProxyHandler.ashx file to the following location on the SharePoint Server: 
            // <Program Files>\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS

            // Supply the Url to the proxy.  Substitute the domain of your SharePoint server.
            wmsLayer.ProxyUrl = "http://bimsp001/_layouts/ProxyHandler.ashx";

            // In order to get the names of the layers, it needs to call getcapabilities
            wmsLayer.SkipGetCapabilities = false;           
            wmsLayer.Version = "1.1.1";
            wmsLayer.Initialized += WMSLayer_Initialized;

            string layerName = "WMS Layer";
            if (wmsLayer.Url.ToLower().EndsWith(""))
            {
                string[] splits = wmsLayer.Url.Split('/');
                layerName = splits[splits.Length - 1];
            }

            wmsLayer.SetValue(MapApplication.LayerNameProperty, layerName);

            MapApplication.Current.Map.Layers.Add(wmsLayer);
        }

        /// <summary>
        /// In the initialized event, the getcapabilities request returns the names of the layers
        /// </summary>
        private void WMSLayer_Initialized(object sender, EventArgs args)
        {
            List<string> layerNames = new List<string>();
            foreach (WmsLayer.LayerInfo layerInfo in wmsLayer.LayerList)
            {
                if (layerInfo.Name != null)
                {
                    layerNames.Add(layerInfo.Name);
                }
            }
            wmsLayer.Layers = layerNames.ToArray(); 
        }
    }
}

The WMS-link I want to add looks like this: http://fbinter.stadt-berlin.de/fb/wms/senstadt/fnp_2009


I have tried to delete the if-statement and split just any URL I add, but this does not solve the problem.
Help would be really appreciated!
Thanks in advance!



EDIT: I just noticed that the layer-name ist displayed in the following dialog and if I want to remove the layer. But just not in Map-Contents on the right-side of the map.
