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? Thanks, Preeti ... View more

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

You haven't added the handler for MouseClick for map in your XAML. <esri:Map x:Name="MyMap" MouseMove="MyMap_MouseMove" Extent="-120, 30, -60, 60" MouseClick="MyMap_MouseClick" > <esri:Map.Layers> <esri:ArcGISTiledMapServiceLayer ID="AGOLayer" Url="http://server.arcgisonline.com/ArcGIS/rest/services/ESRI_ShadedRelief_World_2D/MapServer"/> <esri:ArcGISDynamicMapServiceLayer ID="DynamicLayerCalifornia" Url="http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer" InitializationFailed="Layer_InitializationFailed" /> <esri:GraphicsLayer ID="MyGraphicsLayer" /> </esri:Map.Layers> </esri:Map> </esri:Map.Layers> </esri:Map> ...

I think the spatialReference for the Wells layers is different than the basemap layer. The Extent that is going as parameter to identifytask is using the basemap's extent which probably does not match with coordinate system of the Wells layer and that is causing the identifyTask to not return any results. You can put a breakpoint in MyMap_MouseClick to see what is the extent passed to Identifytask parameters and also in IdentifyTask_ExecuteCompleted to see if any results are returned. --Preeti ...

Actually it is pretty simple. All you need to do is add a toolbaritem to toolbar for identify tool. <esri:ToolbarItem Text="Identify">                 <esri:ToolbarItem.Content>                   <Image Source="/Assets/images/i_about.png" Stretch="UniformToFill" Margin="5" />                 </esri:ToolbarItem.Content>               </esri:ToolbarItem> Create a bool variable and set it true only when "Identify" is clicked. bool identifyclick; private void MyToolbar_ToolbarItemClicked(object sender, ESRI.ArcGIS.Client.Toolkit.SelectedToolbarItemArgs e)     { case 7: //Identify           identifyclick = true;           break;       }     } In Map Mouseclick event check value for this boolean variable to true before running identify logic private void MyMap_MouseClick(object sender, ESRI.ArcGIS.Client.Map.MouseEventArgs e)     {       if (identifyclick)       {         //execute identify code         identifyclick = false // at the end reset the bool variable to deactivate the identify tool.        }      } Basically it will be combination of ToolbarWidget sample and Identify Sample. Most of the code can be copied from Identify sample and pasted as is to toolbarWidget Sample. Attached is the sample XAML with implementation. Hope that helps ... View more
