Reference for editor from Viewer Tool

[GüntherGrill]

I am trying to implement this sample in a ArcGIS Viewer Visual Studio Template project

http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#FeatureLayerSelection

I removed the map part, as the map is defined in the map.xaml in the web project.
I created a user control, modified the code so that the tools would appear after pressing the tool icon:

MapApplication.Current.ShowWindow("Select Range", view);

So far that works however, the functions are greyed out since they are not bound to the layers in the map. How can I bind the editor defined in the user control to the (all) layers in the map?

Thanks,
Günther
