Legend grouplayer template

Question

i need to show map content (map layers) in tree mode, and each type of node (map, grouplayer, layer) must have its own icon.
right now i am using esri Legend control with defined MapLayerTemplate and LayerTemplate. so my grouplayers have the same icon as layers. 
is there a way to set a template for grouplayer?
or maybe it is possible to use default silverlight TreeView control in this case?

- Made recursive method for this!

Recursive is the easiest option. I gave the 'Descendants' code in this thread http://forums.arcgis.com/threads/18999-How-do-I-get-the-selected-LegendItem

In the LayerTemplate, instead of use Then you have to set the ImageSource by code: hook up an handler to Legend.Refreshed event. private void Legend_Refreshed(object sender, Legend.RefreshedEventArgs e) { if (e.LayerItem.LayerItems == null) return; foreach (var layerItem in e.LayerItem.LayerItems) { if (layerItem.IsGroupLayer) layerItem.ImageSource = new BitmapImage(new Uri("/Neolant.TORIS.WebClient;component/Images/group.png", UriKind.Relative)); else layerItem.ImageSource = new BitmapImage(new Uri("/Neolant.TORIS.WebClient;component/Images/layer.png", UriKind.Relative)); } // Note you could also set the ImageSource of e.LayerItem itself (e.g. depending on the type of map service), and you would have to change the MapLayerTemplate as well } Note : if you have more than one possible level of group layers, you'll have to enhance the code to go down the legend tree hierarchy
