I need to project the bing maps to Wgs84 UTM Z19S The bing map is a cached tiled map service and is only available in Web  Mercator. So you can't project bing maps tiles to UTM Z19S. Most generally, the tiled map service is driving the spatial reference of the map, then other services have to be projected in this spatial reference. ... View more

If the Geometry of your objects is 'Points', you can use a TextSymbol or a custom symbol including a TextBlock and bind the text property to an attribute of your graphics. There is a sample of TextSymbol here : http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#AddGraphicsXAML If the geometry is Polyline or Polygon, you can create a new graphicslayer for your labels but you will have to define the label position either by a geometry service (such as LabelPoints) or by a calculation at the client side (such as geometry.Extent.GetCenter()). ...

When are you trying to update your features? (which event?) It might happen that the feature layer is not yet initialized when you try to update and so the collection of graphics is not loaded yet. ... View more

I tried your code and it works fine for me except now the selection color is inoperative. How would you provide for that? Would I need another renderer with a different symbol? You can keep the same renderer but use a symbol managing the 'Selected' state. Example coming from the interactive samples: <esriSymbols:MarkerSymbol x:Key="SelectMarkerSymbol" > <esriSymbols:MarkerSymbol.ControlTemplate> <ControlTemplate> <Ellipse x:Name="Element" Width="15" Height="15" StrokeThickness="10" Stroke="Green" > <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="SelectionStates"> <VisualState x:Name="Unselected" /> <VisualState x:Name="Selected"> <Storyboard> <ColorAnimation Storyboard.TargetName="Element" Storyboard.TargetProperty="(Ellipse.Stroke).(SolidColorBrush.Color)" To="Cyan" Duration="00:00:0.25"/> </Storyboard> </VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> </Ellipse> </ControlTemplate> </esriSymbols:MarkerSymbol.ControlTemplate> </esriSymbols:MarkerSymbol> ...

I agree with Dan, the XamlReader doesn't have the context to understand where to wire your click event handler up. Another option is you to develop your own control managing the click event. ... View more

By reversing the formula we get : var y = -wgs84EarthRadius * Math.Log(Math.Tan((Math.PI / 2 - latitude)/2.0)); Then knowing that Tan²(x/2) = (1 - cos(x)) / (1+cos(x)), we can simplify to: var y = wgs84EarthRadius / 2.0 * Math.Log((1.0 + Math.Sin(latitude)) / (1.0 - Math.Sin(latitude))); Note : latitude in radians ...

I suggest you start following the steps described in this 'Getting Started' video : http://help.arcgis.com/en/webapi/silverlight/help/index.html#//016600000004000000.htm You should end up with a working silverlight application but without editing capabilities. Then you can add editing capabilities by copying and pasting code from the interactive sample. 1) In your MainPage.xaml.cs add this code coming from the sample: private void CancelEditsButton_Click(object sender, RoutedEventArgs e)         {             Editor editor = LayoutRoot.Resources["MyEditor"] as Editor;             foreach (GraphicsLayer graphicsLayer in editor.GraphicsLayers)             {                 if (graphicsLayer is FeatureLayer)                 {                     FeatureLayer featureLayer = graphicsLayer as FeatureLayer;                     if (featureLayer.HasEdits)                         featureLayer.Update();                 }             }         } 2) In your MainPage.xaml add: 2.1) The editor resource        <Grid.Resources>             <esri:Editor x:Key="MyEditor"                          Map="{Binding ElementName=MyMap}"                          LayerIDs="ThreatAreas"                            GeometryServiceUrl="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer"                              />         </Grid.Resources> 2.2) The FeatureLayer to edit <esri:FeatureLayer ID="ThreatAreas"                                 Url="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/HomelandSecurity/operations/FeatureServer/2"                                                 AutoSave="False"                                Mode="OnDemand"                                ValidateEdits="True"                                DisableClientCaching="True" /> 2.3) The whole panel with the editor tools: <Border Background="#FF919191" BorderThickness="1" CornerRadius="5"              HorizontalAlignment="Right"  VerticalAlignment="Top"              Padding="5" BorderBrush="Black" Margin="0,5,5,0"                 DataContext="{StaticResource MyEditor}">             <StackPanel x:Name="EditorTools"

The sample you pointed out is using a standard DataGrid not a FeatureDataGrid : On 'SelectionChanged' event, a graphic is created and is highlighted on the map. You can reuse the same idea with the event MouseEnter of an ItemsControl or with the event SelectionChanged of a ListBox control. ... View more

This has fixed the problem! That's great for now -- but will it create problems for me in the future? No problem, the important point is that the class name declared in the xaml file be in sync with the full classname (rootnamespace + namespace surrounding the class + class name) of the VB project. Why did ESRI put the Namespace in the xaml.vb code sample if it doesn't work? It works if you have no rootnamespace for your project. I guess this has been done to keep VB code close to C# code (and for a C# project there is no rootnamespace). ... View more
