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         } ...

Silverlight viewer has not been updated to use Silverlight API 3.0. It is coming in very near future though..:-) ... View more

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

Can you explain why you want to differentiate them using XAML? Is there any attribute that makes them look different? Have you considered applying UniqueValueRenderer to the layer. UVR will display all different values with different symbol for each type. All you would need is to set the UniqueValueRenderer. Another option may be to define subtypes at the GDB level?

Please take a look at sample http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#LocationToAddress All you need to do is tweak the sample a little bit for adding the returned result of the geocoding to a featureservice. In the codebehind go to in LocatorTask_LocationToAddressCompleted. In this event instead of adding the graphic to the graphic layer, you can add the graphic to your FeatureService(editable FeatureLayer) and call FeatureLayer.SaveEdits() to save the results. Hope this helps! ... View more
