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

Yes it is possible to edit featureLayer outside a map as long as the featurelayer is not readonly. In the following example a feature is being added to a featurelayer not in the Map. The key is to *initialize* the featurelayer and make edits in Intialized event. See code below for reference. private void UpdateFeatureLayer_Click(object sender, RoutedEventArgs e)     {       FeatureLayer Layertobeupdated = new FeatureLayer();       Layertobeupdated.ID = "mylayer";       Layertobeupdated.Url = "http://localhost/ArcGIS/rest/services/MontgomerySimple/FeatureServer/3";       Layertobeupdated.AutoSave = false;            Layertobeupdated.Initialize();       Layertobeupdated.Initialized += new EventHandler<EventArgs>(Layertobeupdated_Initialized);          } void Layertobeupdated_Initialized(object sender, EventArgs e)     {       FeatureLayer fl = sender as FeatureLayer;       Graphic g = new Graphic();       g.Geometry = new ESRI.ArcGIS.Client.Geometry.MapPoint(509314.1673, 685143.8811);       g.Attributes.Add("Name", "abc");       g.Attributes.Add("Service_Details", "Test adding SL");       g.Attributes.Add("Service_Type", "Testing");       g.Attributes.Add("Tracking_Number", "100");       fl.Graphics.Add(g);       fl.SaveEdits();          } Hope this helps! Preeti I found a workaround: you have to add the FeatureLayer to a dummy Map... I know this is quite strange and I really don't like it, but it works. Create a dummy Map: Map map = new Map() {     Extent = new Envelope() {         SpatialReference = new SpatialReference(3857)     } }; Add the FeatureLayer to the Layers collection, then initialize the FeatureLayer and in the Initialized event call the Update method to load the data (to fill the Graphics collection). At this point you have to work with the Graphics: adding, updating, deleting graphics is all you have to do. Then call the SaveEdits method that in turn calls the ApplyEdits method of the internal EditTask (yes, the FeatureLayer has internally an EditTask). Hint: if you have to work only with a subset of features set the Where property of the FeatureLayer before calling Initialize and Update methods. it works, but I don't like this way at all: we are forced to load the FeatureLayer graphics (or a subset of them), working on them, before applying edits, with EditTask this is not necessary avoiding a roundtrip to the REST service (you have only to specify adds, deletes and updates graphics collection to send to the server). ...

I tried following code to copy the Layers (altered from the default visibility) from one map to another and it works fine for me. Basically at the click of copy button I fetched the visible layers of the target ArcGISDynamicMapServiceLayer, created a new ArcGISDynamicMapServiceLayer in destination Map and gave same URL as Source map and set visiblity of layers and add the layer to destination Map. private void copy_Click(object sender, RoutedEventArgs e)     {       ArcGISDynamicMapServiceLayer destinationLayer = new ArcGISDynamicMapServiceLayer();       ArcGISDynamicMapServiceLayer OriginLayer = MyMap.Layers["MyDynamicLayer"] as ArcGISDynamicMapServiceLayer;       //give the URL as the source map's DynamicService Layer       destinationLayer.Url=OriginLayer.Url; //get all the visible layers from source service        List<int> visibleLayerList =           OriginLayer.VisibleLayers != null           ? OriginLayer.VisibleLayers.ToList() : new List<int>(); //set the visiblelayers to what we got from above       destinationLayer.VisibleLayers=visibleLayerList.ToArray(); //add to destination Map       TargetMap.Layers.Add(destinationLayer);     } ...
