Hi all Anyone copy/pasted a polygon from one layer to another using Silverlight thanks This can be done using silverlight too. However you cannot directly add a graphic from one layer to another. You would need to clone the geometry and copy over attributes from LayerAGraphic to LayerBGraphic. Grpahic LayerBGraphic; = new Graphic(); LayerBGraphic.Geometry=ESRI.ArcGIS.Client.Geometry.Geometry.Clone(layerAGraphic.Geometry); foreach (var attrib in layerAGraphic.Attributes)         {           LayerBGraphic.Attributes[attrib.Key] = attrib.Value;         } ...

Hi , I don't see any techinical issue in what you are doing. I tried both of your usecases on http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/HomelandSecurity/operations/FeatureServer/2 and didn't run into any issue. Both cases were successful. For updating I did (MyMap.Layers[1] as FeatureLayer).SelectedGraphics.ToList()[0].Geometry = null; And for adding a new feature, private void Button_Click(object sender, RoutedEventArgs e)         {           Graphic g = new Graphic();           g.Attributes["collection_time"] = DateTime.Now;           g.Attributes["description"] = "Empty Shape";           (MyMap.Layers[1] as FeatureLayer).Graphics.Add(g);         } Try a simple usecase using service above and let us know if you find any problem. ...

Yes until layer is intialzed you can't get its info. So code will look like : public Test()         {             InitializeComponent();             FeatureLayer fl = new FeatureLayer();             fl.Url ="http://services.arcgisonline.com/ArcGIS/rest/services/Demographics/USA_Average_Household_Size/MapServer/1";             fl.Initialized += fl_Initialized;             fl.Initialize();         }         void fl_Initialized(object sender, System.EventArgs e)         {           // you can get layerinfo here         } ...

After all layers are removed and new layers are added you would need to reset the map's extent to extent of all layers. Try this MyMap.Extent=MyMap.Layers.GetFullExtent(); ... View more

Custom Symbols and Rendererer are not supported by Rest API at 10.1. Hence the API downgrades any custom symbols/Renderers to the base type with black color. Note, In a graphicslayer if a custom symbol is found even for one graphic, all symbols are downgraded for that layer. For e.g the symbol below would be printed as black point <esri:SimpleRenderer x:Key="YellowMarkerRenderer">                 <esri:SimpleRenderer.Symbol>                     <esri:SimpleMarkerSymbol Size="20">                         <esri:SimpleMarkerSymbol.Color>                             <RadialGradientBrush>                                 <GradientStop Color="Yellow" Offset="0.578"/>                                 <GradientStop Color="#FF0E0D07" Offset="1"/>                             </RadialGradientBrush>                         </esri:SimpleMarkerSymbol.Color>                     </esri:SimpleMarkerSymbol>                 </esri:SimpleRenderer.Symbol>             </esri:SimpleRenderer> ...

The API does have a property called GeometryType on LayerInfo. You don't need a webclient request to get this property. Basically when the Featurelayer is initialized you can get it like this:   private void FeatureLayer_Initialized(object sender, System.EventArgs e)     {       if ((sender as FeatureLayer).LayerInfo.GeometryType == GeometryType.Polygon)       {         // do  something       }     } ...

What version of API and ArcGIS Server are you using? For ArcGIS Server, please mention if there is any servicepack installed? Generally, in order to get the updated MapDescription, you have to call GetServerInfo on IMapServer again, The following should be the workflow Create IMapServer3 Remove the layer Call IMapServerObjects.RefreshServerObjects Create IMapServer3 Add the layer Call IMapServerObjects.RefreshServerObjects Sample code: IServerContext serverContext; IMapServer2 mapServer; IMapDescription mapDesc; // Access fine-grained ArcObjects IMapServerObjects2 mapServerObj = (IMapServerObjects)mapServer; string strMapName = mapServer.DefaultMapName; IMap map = mapServerObj.get_Map(strMapName); // Add a new group layer to map IGroupLayer groupLayer = serverContext.CreateObject("esriCarto.GroupLayer") as IGroupLayer; groupLayer.Name = "New Group Layer"; map.AddLayer(groupLayer); // Apply changes to MapServer object mapServerObj.RefreshServerObjects(); // Get updated MapServerInfo and MapDescription IMapServerInfo2 mapServerInfo = mapServer.GetServerInfo(strMapName); mapDesc = mapServerInfo.DefaultMapDescription Let me know if this helps...If you want to provide us with your testcase, I will be more than happy to assist you.. ...

If you are using v2.2 , then FeatureDataGrid in v.2.2 will display labels for codedvaluedomains but does not display labels for subtypes.  It will only display the number for subtypes. But in upcoming release you will find dropdowns in FeatureDatagrid for types and Subtypes fields, displaying the labels. ArcGIS API for Silverlight 3.0 beta 1 already includeds this functionality, if you want to give it a try. ... View more
