Can't add ElementLayer when UsAcceleratedDisplay=True, 10.1.1

[KeithMacIntyre]

When in Accelerated Display Mode, an Element Layer can't be added, even outside the AcceleratedDisplayLayers Group.  GraphicsLayers can be added correctly.  According to the release notes, it should be allowed to be added outside the AcceleratedDisplayLayers Group

Code posted below exception

NotImplemented Exception

ElementLayer support not implemented for native rendering. Layer ID: Elements

Hi,

In the code example provided the map is also defined as accelerated. If you remove UseAcceleratedDisplay="True" or change to UseAcceleratedDisplay="False" as shown in the code below the element layer should be added successfully. 

         <esri:Map UseAcceleratedDisplay="False" x:Name="MyMap">             <esri:AcceleratedDisplayLayers >                 <esri:ArcGISTiledMapServiceLayer ID="World Topo Map"  Url="http://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer"/>             </esri:AcceleratedDisplayLayers>             <esri:ElementLayer ID="Elements"></esri:ElementLayer>             <esri:GraphicsLayer ID="Graphics"></esri:GraphicsLayer>         </esri:Map>

Cheers,

Kerrie

I was under the impression that we need the UseAcceleratedDisplay property to be true to have any accelerated layers.  Thank you.

Unfortunately, this still does not solve our problem, because the reason we needed the Accelerated Display was for the new MGRS grid line feature, and the following setting only works if the map's UseAcceleratedDisplay property is set to true.  It would be better if the MGRS grid lines were in a layer rater than a setting.

<esri:Map UseAcceleratedDisplay="True" x:Name="MyMap">
            <esri:Map.AcceleratedDisplay>
                <esri:AcceleratedDisplaySettings GridType="MGRS"></esri:AcceleratedDisplaySettings>
            </esri:Map.AcceleratedDisplay>
            <esri:AcceleratedDisplayLayers >
                <esri:ArcGISTiledMapServiceLayer ID="World Topo Map"  
                    Url="http://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer"/>
                <esri:MessageLayer SymbolDictionaryType="Mil2525C" x:Name="MilitaryLayer" Initialized="MilitaryLayer_Initialized" ></esri:MessageLayer>
            </esri:AcceleratedDisplayLayers>
        </esri:Map>
