I used your code to generate geodatabase from a feature service portal item but I only see 1 replica created. We also have branch versioning enabled on this feature service. What ArcGIS Enterprise version are you using? I tried ArcGIS Enterprise 11.0, utility network version 6. ArcGIS Runtime WPF build 200.2.    ... View more

You can subscribe to `GeometryEditor.PropertyChanged` event and monitor the `GeometryEditor.Geometry` property. If this is a polyline, you can use `PolylineBuilder` it's `IsSketchValid()` method already checks for the minimum set, 2 unique points. You can check the code-snippet in the Asynchronous start task with geometry result section of this blog post. You can have it throw an error or call `GeometryEditor.Stop()` so drawing is completed once you have at most 2 points. ... View more

Thank you to our dear MVP's for remaining engaged in our esri community! Your feedback and contributions are  most invaluable not only to your fellow developers using the Native Maps SDK (Runtime); but especially to us, in the development team, who are continuously learning, growing, and building the product with you. Thank you! ... View more

Inspecting fiddler capture will definitely help you troubleshoot whether the query you're making on the browser is identical to the request made through Runtime.  In addition should they be different... A quick check if you will need to use paging query is to FeatureTable.QueryFeatureCountAsync if the result is more than the LayerInfo.MaxRecordCount and LayerInfo.SupportsPagination is true, you can pass a ResultOffset and MaxFeaturesCount in the QueryParameters. Another cause why query result count is different from server is you may have set a DefinitionExpression on the table which will limit the features accessible to you.   ... View more

Thanks for your feedback. You are right that there's no way of updating or providing your own predicate for AddCommand to have it respond only to touch event.   How are you passing the CommandParameter for AddCommand? This is only enabled with MapPoint. If you don't want AddCommand to execute and add vertex to your polyline/polygon, could you may be provide MapPoint  vertex only when a touch gesture is detected? Alternatively, you can call InsertVertexAfterSelectedVertex method with a more restrictive check. Or you may pause SketchEditor from responding to interaction using its IsEnabled property. If only vertex-editing need to be suspended you can set SketchEditConfiguration.VertexEditMode to SelectionOnly. ... View more

Does layer.InitializeAsync trigger a challenge if you subscribe to ChallengeHandler?    IdentityManager.Current.ChallengeHandler = new ChallengeHandler(async (info) => { var cred = await IdentityManager.Current.GenerateCredentialAsync(info.ServiceUri, "<username>", "<password>"); return cred; });   It may be possible that you need to AddCredential for ServiceUri that match server  https://<portal server>/server/rest   ...

Thanks for reporting this bug. I can reproduce that updating vertex by interaction allows undo/redo while updating vertex by code with MoveSelectedVertex, cannot be undone without the vertex being deleted. It also appears that GeometryChanged event does not report this as move vertex but as move geometry. As a workaround, you may subscribe to SelectedVertexChanged event and use this to track the newly inserted vertex (e.NewVertex.Point will be the unmodified/unsnapped vertex). Whether you interactively add point or call InsertAfterSelectedVertex, this event will fire. ... View more

There may be a few SketchEditor commands that you can specify in XAML (like Complete/Cancel/Undo/Redo/Delete). However, you can only begin a draw in code-behind using one of the StartAsync methods. Based on SketchCreation mode, shape is drawn based on MapView events. For example, tap/click for point or adding vertices in polyline/polygon, drag/move for freehand, arrow, rectangle, triangle, circle, ellipse shapes. Few XAML example code would be to set DataContext to MapView's SketchEditor and use Command Binding. <Grid DataContext="{Binding ElementName=MyMapView,Path=SketchEditor}"> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition /> <ColumnDefinition /> </Grid.ColumnDefinitions> <CheckBox IsChecked="{Binding IsEnabled, Mode=TwoWay}" Content="IsEnabled" /> <CheckBox IsChecked="{Binding IsVisible, Mode=TwoWay}" Content="IsVisible" Grid.Column="1" /> <Slider Minimum="0" Maximum="1" Value="{Binding Opacity, Mode=TwoWay}" Grid.ColumnSpan="2" Grid.Row="1" /> <Button x:Name="AddButton" Content="Add" Command="{Binding AddCommand}" Grid.Row="2" /> <Button Content="Delete" Command="{Binding DeleteCommand}" Grid.Row="2" Grid.Column="1" /> <Button Content="Undo" Command="{Binding UndoCommand}" Grid.Row="3" /> <Button Content="Redo" Command="{Binding RedoCommand}" Grid.Row="3" Grid.Column="1" /> <Button Content="Cancel" Command="{Binding CancelCommand}" Grid.Row="4" /> <Button Content="Complete" Command="{Binding CompleteCommand}" Grid.Row="4" Grid.Column="1" /> </Grid>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ If you have provided SketchEditorConfiguration in resource, you can access this by key and update it's properties using XAML-binding too. <Window.Resources> <esri:SketchEditConfiguration x:Key="MySketchEditConfiguration" /> </Window.Resources> <StackPanel DataContext="{StaticResource MySketchEditConfiguration}"> <ComboBox x:Name="ResizeModes" SelectedItem="{Binding ResizeMode, Mode=TwoWay}" /> <CheckBox IsChecked="{Binding RequireSelectionBeforeDrag, Mode=TwoWay}" Content="RequireSelectionBeforeDrag" /> <CheckBox IsChecked="{Binding AllowMove, Mode=TwoWay}" Content="AllowMove" /> <ComboBox x:Name="VertexEditModes" SelectedItem="{Binding VertexEditMode, Mode=TwoWay}" /> <CheckBox IsChecked="{Binding AllowVertexEditing, Mode=TwoWay}" Content="AllowVertexEditing" /> <CheckBox IsChecked="{Binding AllowRotate, Mode=TwoWay}" Content="AllowRotate" /> </StackPanel>x‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Depending whether you are creating a new shape or editing an existing geometry, you may call any of the StartAsync methods. var editConfig = this.Resources["MySketchEditConfiguration"] as SketchEditConfiguration; var geometry = await MyMapView.SketchEditor.StartAsync(creationMode, editConfig);‍‍ ...

What version of ArcGIS Runtime SDK for .NET are you using? There should be a Stop which may be less awkward to call in code than Complete command but they function the same. Could it be possible that StartAsync for the next draw is triggered, maybe events are stepping on each other? You can also check SketchEditor.IsEnabled and SketchEditor.Geometry?.IsEmpty() == false to know that something is actively being drawn/edited. You can put breakpoint where `catch(TaskCanceledException){}` is handled or where you have any StartAsync call to see if maybe another session cancels the draw. ... View more

When drawAndEdit parameter is true as in your code snippet, after the drawing a shape it will go to edit mode and wait for Complete command. If you wanted to complete draw as soon as you release the mouse/touch, you'd want drawAndEdit=false for shapes like Arrow, Circle, Ellipse, FreehandLine, FreehandPolygon. You can try the following sample and toggle the value for drawAndEdit, use the Complete/Cancel buttons to end draw/edit mode. Another way is to call MyMapView.SketchEditor.StopAsync() at any time which will also complete the draw/edit. <Grid> <esri:MapView x:Name="MyMapView" /> <StackPanel VerticalAlignment="Top" HorizontalAlignment="Right" Orientation="Horizontal"> <ComboBox x:Name="DrawModes" /> <CheckBox x:Name="DrawAndEdit" Content="DrawAndEdit" IsChecked="False" /> <Button Content="Draw" Click="OnDraw" /> <Button Content="Complete" Command="{Binding ElementName=MyMapView, Path=SketchEditor.CompleteCommand}" /> <Button Content="Cancel" Command="{Binding ElementName=MyMapView, Path=SketchEditor.CancelCommand}" /> </StackPanel> </Grid>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ public MainWindow() { InitializeComponent(); DrawModes.ItemsSource = Enum.GetValues(typeof(SketchCreationMode)); MyMapView.Map = new Map(Basemap.CreateTopographicVector()); MyMapView.GraphicsOverlays.Add(new GraphicsOverlay()); } private SimpleFillSymbol _fillSymbol = new SimpleFillSymbol(SimpleFillSymbolStyle.Solid, Color.Blue, null); private async void OnDraw(object sender, RoutedEventArgs e) { try { var drawAndEdit = DrawAndEdit.IsChecked.HasValue && DrawAndEdit.IsChecked.Value; if (DrawModes.SelectedItem is SketchCreationMode creationMode) { var geometry = await MyMapView.SketchEditor.StartAsync(creationMode, drawAndEdit); MyMapView.GraphicsOverlays[0].Graphics.Add(new Graphic(geometry, _fillSymbol)); } } catch (TaskCanceledException) { } catch (Exception ex) { MessageBox.Show(ex.Message, ex.GetType().Name); } } }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

Hi Joe, I think you may be missing a `FeatureTable.UpdateFeatureAsync(feature)` call. You can also check `ArcGISFeatureTable.GetUpdatedFeatures/CountAsync()` if the related feature is included or that this edit results to `ArcGISFeatureTable.HasLocalEdits()` or `Geodatabase.HasLocalEdits()` returning true.  Jennifer ...

Thank you, Joe for the valuable information you sent us. The issue appears to be the definition expression that is on some of the layers.  These expressions are loaded from the webmap, and are filtering out the results returned from GetFeaturesForElementsAsync().  We’ve logged an issue to ignore the expression during this function call.   It looks like the definition expressions are being used to create multiple layers, one for each AssetGroup.  If you have Pro 2.6 and Enterprise 10.8.1, you can create a map in Pro that contains subtype group layers and publish it to a webmap.  This webmap can be consumed using Runtime 100.9, which just shipped today.   We suggest using a single SubtypeGroupLayer instead for each server endpoint (i.e. Gas Device/Line/Junction) when you publish your webmap using ArcGIS Pro.  This will improve performance, and eliminate the need for using the definition expression.  The Runtime equivalent of this layer is SubtypeFeatureLayer. Since it is a sub-class of FeatureLayer, there’s minimal to no change in code necessary. If you are identifying features from this layer, the result will be in SublayerResults.   var feature = result.FirstOrDefault(r => r.SublayerResults.Any(sr => sr.GeoElements.Any(g => g is ArcGISFeature))) ?.SublayerResults?.FirstOrDefault()?.GeoElements?.FirstOrDefault() as ArcGISFeature;‍‍   ...

I think I have a reproducer now. However, the difference in numbers is not as big as yours and does not change if I create UtilityNetwork with or without a map. Electric Distribution Line Unique Elements `4052` vs Features From Elements `4066` (more features than elements) Electric Distribution Junction Unique Elements `3334` vs Features From Elements `3334`  Electric Distribution Device Unique Elements `5045` vs Features From Elements `5425` (more features than elements) var FeatureServerUrl = "https://sampleserver7.arcgisonline.com/arcgis/rest/services/UtilityNetwork/NapervilleElectric/FeatureServer"; var map = new Map(Basemap.CreateDarkGrayCanvasVector()); map.InitialViewpoint = new Viewpoint(InitialExtent); map.OperationalLayers.Add(new FeatureLayer(new Uri($"{FeatureServiceUrl}/115"))); map.OperationalLayers.Add(new FeatureLayer(new Uri($"{FeatureServiceUrl}/110"))); map.OperationalLayers.Add(new FeatureLayer(new Uri($"{FeatureServiceUrl}/100"))); await map.LoadAsync(); _un = await UtilityNetwork.CreateAsync(new Uri(FeatureServiceUrl), map); var networkSource = _un.Definition.GetNetworkSource("Electric Distribution Device"); var assetGroup = networkSource?.GetAssetGroup("Circuit Breaker"); var assetType = assetGroup?.GetAssetType("Three Phase"); var terminal = assetType?.TerminalConfiguration?.Terminals?.FirstOrDefault(t => t.Name == "Source"); var globalId = Guid.Parse("{B8493B23-B40B-4E3E-8C4B-0DD83C28D2CC}"); var element = _un.CreateElement(assetType, globalId, terminal); var parameters = new UtilityTraceParameters(UtilityTraceType.Connected, new[] { element }); var result = await _un.TraceAsync(parameters); if (result.FirstOrDefault() is UtilityElementTraceResult elementResult) { if (elementResult.Warnings.Count > 0) MessageBox.Show(string.Join("\n", elementResult.Warnings), "Trace Result Warnings", MessageBoxButton.OK); foreach (var layer in MyMapView.Map.OperationalLayers.OfType<FeatureLayer>()) { var elements = elementResult.Elements.Where(el => el.NetworkSource.FeatureTable == layer.FeatureTable); var features = await _un.GetFeaturesForElementsAsync(elements); var distinctIds = (from f in elements select f.ObjectId).Distinct(); System.Diagnostics.Debug.WriteLine($"{layer.FeatureTable.DisplayName}\t:\t Unique Elements `{distinctIds.Count()}` vs Features From Elements `{features.Count()}`"); layer.SelectFeatures(features); } }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ In your case, could there be layers that did not load or required credential?

The 5856 elements may not be distinct and may also be belonging to other layers.
