FeatureLayer and the RendererTakesPrecedence property

MiriRevivo

Hello,

I'm trying to use the RendererTakesPrecedence property on a FeatureLayer in order to change the symbols applied to the features by the renderer applied to the layer in the map service it is loaded from.
When in AcceleratedDisplay mode, this property is ignored, and the feature layer gets the renderer applied to it by the service (not the expected behavior).
When using the regular WPF rendering engine - it is respected.

I found this similar issue that was also present in the Silverlight API (but obviously with no relation to the AcceleratedDisplay):
http://forums.arcgis.com/threads/99127-FeatureLayer-doesn-t-honor-RendererTakesPrecedence

Is this a bug? Known limit in the Accelerated mode?

Thanks,
Miri.

Hi Miri,

What version of the API are you using? I just tested 10.2, 10.2.2 and the imminent 10.2.3 and it behaves as expected - when FeatureLayer.RendererTakesPrecedence is false, the individual symbols I explicitly defined on each Graphic are used. However, when RendererTakesPrecedence is true (the default), all Graphics are symbolized as per the service-defined renderer.

public MainWindow() {  InitializeComponent();   ESRI.ArcGIS.Client.LayerCollection.LayersInitializedHandler layerInitializedHandler = null;   BitmapImage bi0 = new BitmapImage(new Uri("pack://application:,,,/Aqua_Ball_Green_32.png"));   PictureMarkerSymbol pms = new PictureMarkerSymbol()  {   Source = bi0,  };   layerInitializedHandler += (s, e) =>   {   MyMap.Layers.LayersInitialized -= layerInitializedHandler;    FeatureLayer featureLayer = new FeatureLayer()   {    ID = "Fire Incidents",    Url = "http://sampleserver6.arcgisonline.com/arcgis/rest/services/Wildfire/FeatureServer/0",    RendererTakesPrecedence = false,   };    EventHandler updateCompleted = null;    updateCompleted += (x, y) =>    {    featureLayer.UpdateCompleted -= updateCompleted;          foreach (var graphic in featureLayer.Graphics)    {     if (graphic.Geometry is MapPoint)     {      graphic.Symbol = pms;     }    }   };    featureLayer.UpdateCompleted += updateCompleted;    MyMap.Layers.Add(featureLayer);  };   MyMap.Layers.LayersInitialized += layerInitializedHandler; }  <Grid>  <esri:Map x:Name="MyMap" UseAcceleratedDisplay="True">         <esri:ArcGISTiledMapServiceLayer ID="World Topo Map"                      Url="http://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer"/>     </esri:Map> </Grid>

Cheers
