This error usually occurs when the namespace for Xaml and Code-behind do not match. Have you tried building this in VS2010?  Do you get the same compile error?  Can you check that all project references are there (there should be warning icon next to them if they are not)? Can you also check project properties for namespace? ... View more

Hi Kevin, What issues are you having with ShowCoordinatesBehavior? ... View more

Sure you will need to create a FeatureLayer that represent the RelatedTable and if you want to add an entry to this table, you will need to add Graphics with attributes matching the fields of this table. If you set AutoSave to false, you need to explicitly call SaveEdits(). ... View more

For a FeatureLayer you can investigate the attribute type based on the layer's LayerInfo.Fields. ... View more

You are correct, setting Fill to Transparent should give you the 'hollow' graphic. Here's one way of defining your Renderer (under Resources): <esri:SimpleFillSymbol x:Key="MySimpleFillSymbol"                                Fill="Transparent"                                BorderBrush="Black"                                BorderThickness="2" />         <esri:SimpleRenderer x:Key="MySimpleRenderer" Symbol="{StaticResource MySimpleFillSymbol}"/> Instead of overwriting the FeatureSymbol, you can set the Renderer like so: <esri:FeatureLayer ID="Polygon"                                                              Renderer="{StaticResource MySimpleRenderer}"                               Url="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/BloomfieldHillsMichigan/LandusePlanning/FeatureServer/2" /> It's possible that your layer already defines a renderer that's why your FeatureSymbol was not used. To find out you can visit the layer's Url in your browser and look for "DrawingInfo" - this defines the layer's renderer. ... View more

You can use WebClient DownloadStringAsync and parse the result into an XDocument. Based on the XML you provided, it seems like you can use a GraphicsLayer with UniqueValueRenderer (Attribute="precinct") that uses SimpleFillSymbol. Your UniqueValueRendererInfos will have a different color per precinct value.  By setting the renderer, you do not have to create a symbol on individual graphics. But you will still need to create each graphic based on the ward information you just parsed so that each ward becomes a graphic in your GraphicsLayer with geometry from the given pointcollection, and attributes from the given "name" and "precinct" values. You can look at our SDK samples for guide: esriurl.com/slsdk2. Good luck. ... View more

You can replace the ListBox ItemsSource="{Binding ElementName=MyMap, Path=Layers.[DynamicLayerCalifornia].Layers}" with an instance of ObservableCollection<LayerInfo> that gets populated when dynamic layer is initialized. Set the dynamic layer's VisibleLayers to an empty int[]. You also need to remove IsChecked="{Binding DefaultVisibility}" from the CheckBox. With these minor tweaks in the sample, you can control the sublayer visibility using the listbox.                 <ListBox Margin="0,5,0,0"                          x:Name="LayerList"                                                 Grid.Row="1">                     <ListBox.ItemTemplate>                         <DataTemplate>                             <CheckBox Margin="2"                                       Name="DynamicLayerCalifornia"                                       Content="{Binding Name}"                                                                            Tag="{Binding ID}"                                       ClickMode="Press"                                       Click="CheckBox_Click" />                         </DataTemplate>                     </ListBox.ItemTemplate>                 </ListBox>         private ObservableCollection<LayerInfo> layers = new ObservableCollection<LayerInfo>();         public MainPage()         {             InitializeComponent();             this.LayerList.ItemsSource = layers;         }         private void ArcGISDynamicMapServiceLayer_Initialized(object sender, EventArgs e)         {             ESRI.ArcGIS.Client.ArcGISDynamicMapServiceLayer dynamicServiceLayer =                 sender as ESRI.ArcGIS.Client.ArcGISDynamicMapServiceLayer;             foreach (LayerInfo l in dynamicServiceLayer.Layers)                 layers.Add(l);             dynamicServiceLayer.VisibleLayers = new int[] { };         } ...

This is one way of finding the nearest geometry but it can be optimized. This sample assumes you are only checking against one layer and will select the closest graphic. The con for doing this is, you will be making async call on every graphic. You might want to refer to Buffer a Point and Intersect samples too. Another idea is to buffer the point returned by MapClick until you find geometries intersecting the buffered point. These intersecting geometries become your candidates for calling DistanceAsync. This may limit the number of async calls you make. At worse case, you may need to keep buffering the point only to find all geometries will intersect it, which means you will be calling DistanceAsync on all geometries anyway. I'm not sure how likely this scenario is but you have to remember too that there can be at most 1000 features returned for ArcGIS Server 10 or 500 for ArcGIS Server 9.31.         public MainPage()         {             InitializeComponent();             polygonLayer = this.MyMap.Layers["Polygon"] as FeatureLayer;             geometryService = new GeometryService("http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer");             geometryService.DistanceCompleted += new EventHandler<DistanceEventArgs>(GeometryService_DistanceCompleted);             distanceParameter = new DistanceParameters()             {                 DistanceUnit = LinearUnit.Kilometer,                 Geodesic = true             };         }         FeatureLayer polygonLayer;         GeometryService geometryService;         DistanceParameters distanceParameter;         Graphic closestGraphic;         double distanceRecorded;         private void MyMap_MouseClick(object sender, Map.MouseEventArgs e)         {             closestGraphic = null;             distanceRecorded = 0;             if (polygonLayer != null && polygonLayer.Graphics != null && polygonLayer.Graphics.Count > 0)             {                 int i = 0;                 Graphic g = polygonLayer.Graphics;                 geometryService.DistanceAsync(e.MapPoint, g.Geometry, distanceParameter, new object[]{polygonLayer.Graphics, i, e.MapPoint});             }         }            private void GeometryService_DistanceCompleted(object sender, DistanceEventArgs e)         {             object[] distanceParams = e.UserState as object[];             if (distanceParams != null && distanceParams.Length == 3 &&                 distanceParams[0] is GraphicCollection && distanceParams[1] is int                 && distanceParams[2] is MapPoint)             {                 GraphicCollection graphics = distanceParams[0] as GraphicCollection;                 int index = (int)distanceParams[1];                 MapPoint mp = distanceParams[2] as MapPoint;                 if (closestGraphic == null || distanceRecorded > e.Distance)                 {                     distanceRecorded = e.Distance;                     closestGraphic = graphics[index];                 }                 index++;                 if (index < graphics.Count)                 {                     Graphic g = polygonLayer.Graphics[index];                     geometryService.DistanceAsync(mp, g.Geometry, distanceParameter, new object[] { polygonLayer.Graphics, index, mp });                 }                 else                 {                     foreach (Graphic g in graphics)                     {                         if (g == closestGraphic)                             g.Selected = true;                         else                             g.Selected = false;                     }                                    }             }         } ...

If you make your stateNameQuery an ObservableCollection and have both combobox ItemSource set to this, you can set the second combobox SelectedItem="{Binding ElementName=vejComboBox, Path=SelectedItem, Mode=TwoWay}". It might also be a good idea to check for duplicates, before adding to your stateNameQuery. To make the combobox editable and autocomplete, you will need to create your own style. You can read up on it here: http://silverlightfeeds.com/post/53/Use_Styles_for_an_editable_Silverlight_ComboBox.aspx ... View more

Based on the link you provided, there is a way to unblock the files inside the zip collectively if you are using Windows 7. You did not do anything wrong, it's just that these files were marked unsafe and needed to be unblocked prior to use. For Windows 7, 1. Right click on the zip file 2. Click on 'Properties' 3. Choose 'Unblock' in the 'Attributes' section 4. Extract file Note: If you unzip the file before unblocking, all files in the extracted folder are flagged as unsafe. ... View more
