Hello,I am trying to apply the examples:http://help.arcgis.com/en/webapi/silverlight/3.0/apiref/ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.ArcGISDynamicMapServiceLayer~CreateDynamicLayerInfosFromLayerInfos.htmlhttp://help.arcgis.com/en/webapi/silverlight/3.0/apiref/ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.ArcGISDynamicMapServiceLayer~DynamicLayerInfos.htmlhttp://help.arcgis.com/en/webapi/silverlight/3.0/apiref/ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.LayerDrawingOptionsCollection.htmlto the my situation. I would like to create a color scheme for a feature class exposed through a service based on a set of data located in a separate table. I've tried several iterations of solutions just to try and make it work and the one the came closest was when I I created a join through arcmap to expose the data through the feature class attributes then created a dynamic layer and assigned it a unique value renderer that pointed at the desired joined attribute in the feature service. But by having the joined attribute exposed through the service it seems to break the unique value renderer to where it will only use the default symbol... I've confirmed the code below works when I remove the join from the service and base the renderer on a different attribute.Is there something I'm missing? Is there a better approach given this scenario? Any help would be greatly appreciated.Thanks! djordan void SetImportedMapRenderers(Layer _importedLayer) { // Get the ArcGISDynamicMapServiceLayer that was defined in XAML but not shown visually in the Map.
