It might be easier to use Expression Blend for this or you can also do this: Add reference to the following assemblies: ESRI.ArcGIS.Client.Behaviors.dll System.Windows.Interactivity Having the following XAML namespace definitions: xmlns:esri="http://schemas.esri.com/arcgis/client/2009"  xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity" should be sufficient. This will allow you to     <i:Interaction.Behaviors>           <esri:ConstrainExtentBehavior ConstrainedExtent="-120,30,-60,60" />     </i:Interaction.Behaviors> Jennifer ... View more

Unfortunately these Envelope properties (XMin, YMin, XMax, YMax) are not dependency properties that's why you cannot bind to them. Jennifer ... View more

You would usually use MouseLeftButtonDown event to do this, get the screen point and translate them to the actual map coordinates. System.Windows.Point screenPoint = args.GetPosition(MyMap); ESRI.ArcGIS.Client.Geometry.MapPoint mapPoint = MyMap.ScreenToMap(screenPoint); You can refer to this blog for Binding EventArgs to a Command http://silverlight-essentials.com/blog/ Jennifer ...

After you've added the graphics to the layer in the DrawComplete event handler, you can disable the draw object explicitly setting its IsEnabled property to false or flipping its value like and setting DrawMode property to None if it is not already None. myDrawObject.IsEnabled = !myDrawObject.IsEnabled; if (myDrawObject.DrawMode != DrawMode.None)     myDrawObject = DrawMode.None; Jennifer ...

You need to call this after all layers have been added, that's the tricky part since you add the layers asynchronously and there's no guarantee that all layers will be added if credentials should fail, right? To test that you can change the order of the map layers in code, you can add them in a button click event. Once you know all layers were added, click the button and see that the order of layers have been modified. Jennifer ... View more

If I understood your question correctly, you want to be able to add to/remove from selection without clicking on any button and only using your keyboard and mouse. If that is the case, you can listen to KeyDown and pass the proper command parameter on the editor's Select command based on the pressed key.         public MainPage()         {             InitializeComponent();             this.KeyDown += new KeyEventHandler(MainPage_KeyDown);             editor = this.LayoutRoot.Resources["MyEditor"] as Editor;         }         Editor editor;         void MainPage_KeyDown(object sender, KeyEventArgs e)         {             if (editor == null) return;             if (e.Key == Key.Ctrl)                 editor.Select.Execute("Add");             else if (e.Key == Key.Shift)                 editor.Select.Execute("Remove");             else if (e.Key == Key.Escape)                            editor.CancelActive.Execute(null);         } Jennifer ...

Since you are adding the layers to the map based on an asynchronous event (DownloadStringCompleted), you cannot expect the order of the layers to be always the same. If you really have to modify the order of the layers in your map, once all layers have been added to your map you can modify the existing layer collection by doing the following:             Layer Aerials2005 = this.MyMap.Layers["Aerials2005"];             Layer Buildings = this.MyMap.Layers["Buildings"];             Layer Parcels = this.MyMap.Layers["Parcels"];             LayerCollection lc = this.MyMap.Layers;             lc.Clear();             if (Aerials2005 != null)                 lc.Add(Aerials2005);             if (Buildings != null)                 lc.Add(Buildings);             if (Parcels != null)                 lc.Add(Parcels); Jennifer ...

I tried this sample in both WPF and SL application. I placed debug break points to the EndSaveEdits and SaveEditsFailed too. It would help to familiarize yourself with the feature layer first, it's field names and expected values. http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/BloomfieldHillsMichigan/LandusePlanning/FeatureServer/2 XAML-code:   <UserControl.Resources>         <esri:SimpleFillSymbol x:Key="MyYellowFillSymbol"                                       Fill="YellowGreen"                                       BorderBrush="Transparent"                                       BorderThickness="2" />         <esri:SimpleFillSymbol x:Key="MyRedFillSymbol"                                       Fill="Red"                                       BorderBrush="Transparent"                                       BorderThickness="2" />         <esri:UniqueValueRenderer x:Key="MyUniqueValueRenderer"                                   Attribute="symbolname">             <esri:UniqueValueRenderer.Infos>                 <esri:UniqueValueInfo Value="Residential - Very Low Density"                                       Symbol="{StaticResource MyRedFillSymbol}" />                 <esri:UniqueValueInfo Value="Residential - Low Density"                                       Symbol="{StaticResource MyYellowFillSymbol}" />             </esri:UniqueValueRenderer.Infos>         </esri:UniqueValueRenderer>     </UserControl.Resources>     <Grid x:Name="LayoutRoot" Background="White">         <esri:Map x:Name="MyMap">             <esri:ArcGISTiledMapServiceLayer Url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer" />             <esri:FeatureLayer ID="towers"                                Url="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/BloomfieldHillsMichigan/LandusePlanning/FeatureServer/2"                                Where="1=1"                                Renderer="{StaticResource MyUniqueValueRenderer}"                                                    EndSaveEdits="FeatureLayer_EndSaveEdits"                                SaveEditsFailed="FeatureLayer_SaveEditsFailed"                                MouseLeftButtonDown="FeatureLayer_MouseLeftButtonDown">                 <esri:FeatureLayer.OutFields>                     <sys:String>symbolname</sys:String>                 </esri:FeatureLayer.OutFields>             </esri:FeatureLayer>         </esri:Map> </Grid> Code-Behind:         private void FeatureLayer_MouseLeftButtonDown(object sender, ESRI.ArcGIS.Client.GraphicMouseButtonEventArgs e)         {             Graphic g = e.Graphic;             string currentValue = (string) g.Attributes["symbolname"];             if(currentValue.Contains("Very"))                 g.Attributes["symbolname"] = "Residential - Low Density";             else                 g.Attributes["symbolname"] = "Residential - Very Low Density";         }         private void FeatureLayer_EndSaveEdits(object sender, ESRI.ArcGIS.Client.Tasks.EndEditEventArgs e)         {         }         private void FeatureLayer_SaveEditsFailed(object sender, ESRI.ArcGIS.Client.Tasks.TaskFailedEventArgs e)         {         } Jennifer ...

You can use a GraphicsLayer since these points will only be used to display on the map. And then maybe apply a SimpleRenderer to your GraphicsLayer so that each point uses the same marker symbol. In code-behind, you can add the graphics with a MapPoint geometry based on the lat/lon values retrieved from your table. Jennifer ... View more

With ArcGIS Silverlight/WPF API v2.0, you can use QueryTask (similar to the JavaScript sample as Dominique cited below). QueryTask qt = new QueryTask(featureLayer.Url); qt.DisableClientCaching = true; RelationshipParameter rp = new RelationshipParameter(); rp.ObjectIds = new int[] { objectId }; //object id from featureLayer rp.OutFields = new string[] { "agree_with_incident" }; //fields from related table rp.RelationshipId = relationshipId; //can be retrieved from featureLayer's LayerInfo.Relationships qt.ExecuteRelationshipQueryCompleted += qt_ExecuteRelationshipQueryCompleted; qt.ExecuteRelationshipQueryAsync(rp); Jennifer ...

Sure, in the same MouseLeftButtonDown event handler, you can do the following: GraphicsLayer l = sender as GraphicsLayer; IEnumerable<Graphic> graphics = l.FindGraphicsInHostCoordinates(e.GetPosition(null)); This gives you an enumerable of graphics contained in that cluster. Jennifer ... View more

Looking at your code, you are trying to add graphics to a MapServer layer. This is read-only and any edits to it will not be applied, even if you refresh your dynamic layer. Jennifer ... View more

If you add a MouseLeftButtonDown event on the GraphicsLayer with clusterer, e.Graphic is your node that represents the cluster and you can view its attributes (Count, Size, Color). Jennifer ... View more

The idea for using "Keyboard" as CommandParameter is to allow user to use a single button for Add to/Remove from selection using hot keys to distinguish the selection mode (Ctrl for Add, Shift for Remove). But if you do not want to use keyboard, you can simply do two buttons: <Button x:Name="AddSelectButton" Content="Add" Command="{Binding Select}" CommandParameter="Add"/> <Button x:Name="RemoveSelectButton" Content="Remove" Command="{Binding Select}" CommandParameter="Remove"/> Jennifer ...
