Newbie question: how to add feature layer symbol to a layer list?

Question

I adapted the following example to make layer list for a map with 3 FeatureLayer and 1 ArcGISTiledMapServiceLayer: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#LayerList The layer list works fine but does not show the symbol for each FeatureLayer. I found that I don't know how to adapt the above example and add the symbol graphics. Can you tell me some idea? Thank you. Following is the map layers I am in my XAML code: *********************************************************** ***********************************************************************

However, after trying around I still could find out how to use the FeatureSymbol property. It is in Symbol class of ESRI.ArcGIS.Client.Symbols Namespace, I don't know how to put it into the StackPanel and arrange it with other controls such as text blocks and checkboxes. As Morten said, you can use the ESRI.ArcGIS.Client.Toolkit.Primitives.SymbolDisplay control. For example the following code will give the attached result: �?? �?? LayerList.JPG

The REST API doesn't expose legend information, so there is no simple way to do this.
If you are hitting an ArcGIS Server 10 (your example aboe is not!), FeatureLayers do get render information from the server, but you will have to go through each symbol defined on the renderer (there could be more whan one symbol depending on what service you are hitting) and set these symbols on the Symbol property for the ESRI.ArcGIS.Client.Toolkit.Primitives.SymbolDisplay control.
