I thought I'd seen a fix for this last week in the forums but can't find it today!  I'm trying to add a graphic to a graphics layer using an image defined in Resources of my user control but if I use a PictureMarkerSymbol nothing draws whereas a SimpleMarkerSymbol does.  The ESRI Identify sample uses a PictureMarkerSymbol so I know it's possible.  I have a user control that a user can enter a Lat-Long and the map will zoom to it and (should) add a graphic at the local they entered.  I'm wondering if it's a location issue - my control is /UserControls/ZoomToXY and references a PNG in /UserControls/Images as the source for the PictureMarkerSymbol.  I've tried putting the PNG up a level in the /Images folder but that doesn't seem to solve the problem either.  Anyone know what I'm missing?  Thanks, Terry XAML for resources:     <Grid x:Name="LayoutRoot" Background="Transparent">         <Grid.Resources>             <esri:PictureMarkerSymbol x:Name="DefaultPictureSymbol" OffsetX="13" OffsetY="22"                  Source="/Images/IdentifyMapIcon.png"  />             <esri:SimpleMarkerSymbol x:Name="SMStest" Color="Red" Size="12" />         </Grid.Resources> Code behind:             //add graphic to map             GraphicsLayer graphicsLayer = (GraphicsLayer)_Map.Layers[_GraphicsLayer];             graphicsLayer.ClearGraphics();             //this does not work             Graphic graphic = new Graphic() { Geometry = ptMapPoint, Symbol = DefaultPictureSymbol };             graphicsLayer.Graphics.Add(graphic);             //using a SimpleMarkerSymbol works             Graphic graphic2 = new Graphic() { Geometry = ptMapPoint, Symbol = SMStest };             graphicsLayer.Graphics.Add(graphic2); ...

I'm working on an Identify tool that works against all layers in the map.  The code is pretty straight forward and very similar to the ESRI samples as shown below.  It works great in most cases including dynamic services with projections different than the map. Where I'm having a problem is getting the results back for a service where security has been enabled in ArcGIS Server (using windows accounts as the store & I am in a group with access to the services).  When the Identity executes against one of these services I see 2 Requests being sent in Fiddler - the 1st returns a 401 not authorized error and the 2nd contains the results of the identify.  I believe this double request scenario is normal as it does this if I pan the map and it makes an export image request against the service - please correct me if I am wrong though.  However I never get the valid results in the ExecuteCompleted routine but the layer draws fine in the map.  What am I missing with these secured services?  Thanks,  Terry       public void Identify(MapPoint ptMapPoint)         {             //called from btnIdentify on the toolbar - runs an Identiy on all map layers             IdentifyTask IDTask;             IdentifyParameters idParams = new IdentifyParameters()                 {                     Geometry = ptMapPoint,                     MapExtent = _Map.Extent,                     Width = (int)_Map.ActualWidth,                     Height = (int)_Map.ActualHeight,                     LayerOption = LayerOption.all,                     SpatialReference = _Map.SpatialReference                 };              for (int i = 0; i < _Map.Layers.Count; i++)             {                 if (!(_Map.Layers is GraphicsLayer))                 {                     IDTask = new IdentifyTask();                     IDTask.ExecuteCompleted += IdentifyTask_ExecuteCompleted;                     IDTask.Failed += IdentifyTask_Failed;                     IDTask.Url = MapUtils.GetLayerURL(_Map.Layers);                     IDTask.ExecuteAsync(idParams, i);                 }                             }                     }         private void IdentifyTask_ExecuteCompleted(Object sender, IdentifyEventArgs args)         {             //simplified for debugging...             if ((args.IdentifyResults != null) && (args.IdentifyResults.Count > 0))             {                 MessageBox.Show((sender as IdentifyTask).Url + " num results= " + args.IdentifyResults.Count);             }             else             {                 MessageBox.Show((sender as IdentifyTask).Url + " has no ID results");             }          }         private void IdentifyTask_Failed(Object sender, TaskFailedEventArgs e)         {             MessageBox.Show("Identify failed.

I'm trying to modify the sublayer list example but am having issues as my map service contains group layers. If the user clicks the checkbox for a sub layer it should only show if the parent (or in my case parent and grandparent) layers are also visible.  While a dynamic layer has the ChildLayers property it has no built in concept of ParentLayer.  I'm getting stuck on how to recurse up the sublayer tree and visibility of parent/grandparent layers - does anyone else have a code snippet on how to do this efficiently?  Thanks, TG ...
