This is expected behavior. You can use the following sample to test. Pan the map and draw the polygon using Add button. Click Zoom to zoom to full extent. Check Normalize and click the graphic to update the geometry. Click zoom to full extent again. Notice that when you update the geometry and the polygon is split in half, the extent changes. <Grid x:Name="LayoutRoot">   <Grid.Resources>    <esri:SimpleFillSymbol x:Key="RedFillSymbol" Fill="#66FF0000" BorderBrush="Red" BorderThickness="2" />    <esri:Editor x:Key="MyEditor" Map="{Binding ElementName=MyMap}" EditCompleted="Editor_EditCompleted"/>   </Grid.Resources>   <esri:Map x:Name="MyMap" WrapAround="True" Background="White">    <esri:ArcGISTiledMapServiceLayer ID="PhysicalTiledLayer"                                              Url="http://services.arcgisonline.com/ArcGIS/rest/services/NGS_Topo_US_2D/MapServer"/>    <esri:GraphicsLayer ID="MyGraphicsLayer" MouseLeftButtonDown="GraphicsLayer_MouseLeftButtonDown" />   </esri:Map>   <StackPanel  VerticalAlignment="Top" HorizontalAlignment="Center">    <Button Content="Add" DataContext="{StaticResource MyEditor}"     Command="{Binding Add}" CommandParameter="{StaticResource RedFillSymbol}"/>    <Button Content="Zoom" Click="Button_Click"/>    <CheckBox x:Name="NormalizeGeometry" Content="Normalize" IsChecked="False"/>   </StackPanel> </Grid>   private void Button_Click(object sender, RoutedEventArgs e)   {    var l = MyMap.Layers["MyGraphicsLayer"] as GraphicsLayer;    MyMap.ZoomTo(l.FullExtent);   }   private void Editor_EditCompleted(object sender, Editor.EditEventArgs e)   {    if (e.Action == Editor.EditAction.Add)    {     foreach (var edit in e.Edits)      edit.Graphic.Attributes["OriginalGeometry"] = edit.Graphic.Geometry;    }   }   private void GraphicsLayer_MouseLeftButtonDown(object sender, GraphicMouseButtonEventArgs e)   {    var originalGeometry = e.Graphic.Attributes["OriginalGeometry"] as Polygon;    if (NormalizeGeometry.IsChecked.HasValue && NormalizeGeometry.IsChecked.Value)     e.Graphic.Geometry = Geometry.NormalizeCentralMeridian(originalGeometry);    else     e.Graphic.Geometry = originalGeometry;   } ...

Yes, FeatureLayer.UndoEdits() is supported in v2.2 http://help.arcgis.com/en/webapi/silverlight/2.2/apiref/ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.FeatureLayer~UndoEdits.html. Note, however that in order to have a chance to undo edits, FeatureLayer.AutoSave must be False. Otherwise, all edits (geometry or attribute) will be committed and saved to the server immediately. ... View more

You might want to check EditAction (i.e. e.Editor.EditAction.Add), your code currently will set the attribute regardless of completed command. If this is not a concern, you can also use FeatureLayer.BeginSaveEdits event, if any edit should trigger this attribute value change. Another option is to update your service-defined PrototypeAttributes. EditorWidget contains TemplatePicker that allows you to add features based on feature type. Based on the selected feature type, a list of default attributes are used.

Yes, you can use 2nd parameter UserState, this can be any data type, which you can cast to the correct type in the completed event.    geometryService.AreasAndLengthsCompleted += (s, e) =>     {      var originalGraphics = e.UserState as List<Graphic>;      if (originalGraphics != null)      {      };     };    geometryService.AreasAndLengthsAsync(graphics, graphics); ...

The only client-side calculation the API offers for finding intersection is in Envelope geometry which may not be as accurate as you need it to be when finding interesection between Polylines. The other option would be to use GeometryService.Intersect. ... View more

Does your Graphic.Symbol have a select state? (See SelectLineSymbol in XAML-code) http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#SelectGraphics.

If FeatureLayer.AutoSave is True (this is default setting), FeatureLayer.SaveEdits() will not have any bearing in your app since edits are committed (submitted to server) immediately. If you want to make saving explicit, set AutoSave=False. You don't have much control over FeatureDataForm from EditorWidget though. Instead you can use FeatureDataForm outside EditorWidget: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#ToolkitFeatureDataForm. You can subscribe to FeatureDataForm.EndEdits instead of Graphic.AttributeValueChanged. EndEdits fires when apply button is clicked. You can call layer.SaveEdits() then. ... View more
