Using ArcGIS Runtime for .NET 100.0 and WPF. I have a geometry created using the sketch editor ...        _traceGeometry = await Mapview.SketchEditor.StartAsync(SketchCreationMode.Polyline, true); Then later I want to create a feature using this geometry. However, the feature class has z values. So when I try to save it via ...       await table.AddFeaturesAsync(features); I get an exception: "The shape must have a Z value." My question is how can I add z values to this geometry? Do I need to recreate a new geometry using PolylineBuilder and adding a z-value for each point? Initially all points can (and should) have 0 for a z-value, but eventually, we will run a calculation that adds z-values based on underlying elevation. Alternatively, will the sketch editor create a z-enabled geometry if there is underlying elevation data included as a map layer? ... View more

I have generated a runtime geodatabase from a sync-enabled feature service as described on this page ... Create an offline map—ArcGIS Runtime SDK for .NET | ArcGIS for Developers . That works OK, but is somewhat unreliable in that I had to try multiple times to get it to download. Maybe I'll post a separate question on that. In code I do something like this to setup my map ... var gdb = await Geodatabase.OpenAsync(master.GeodatabasePath); foreach (var table in gdb.GeodatabaseFeatureTables) {     await table.LoadAsync();     var layer = new FeatureLayer(table);     layer.Id = table.TableName;     mapView.Map.OperationalLayers.Add(layer); } Then later ... var attributes = new Dictionary<string, object>(); attributes.Add("PlanId", 1); attributes.Add("PlanGuid", Guid.NewGuid()); var layer = Mapview.Map.OperationalLayers["Aoi"] as FeatureLayer; var newFeature = layer.FeatureTable.CreateFeature(attributes, _aoiGeometry); await layer.FeatureTable.AddFeatureAsync(newFeature); ... That works fine too. However, I noticed that the feature is written immediately to the attached geodatabase. Is there a way to delay writing to the database until I make an explicit call? I suppose I could initially create graphics, and then when I want to persist them, create features from the graphics. That's a simple enough concept but seems convoluted in that I would also have to created a bunch of graphics from existing features every time my query criteria changes. Or is there a better workflow instead? My goal is to work offline only. We will never sync back to the server after creating the initial (empty) geodatabase. I do need to be able to perform all of the basic create, update, insert, select operations on the feature data. Would FeatureCollection be a viable alternative? ... View more

I have code that I wrote in .NET runtime 10.2.7 using the MapView.Editor that allows the user to draw a polyline on the map. I'm sure it came from one of the samples. I'm trying to do the same thing in Quartz (WPF only), and it doesn't seem to work as expected. When I click my button, the map is clearly in editor mode, and I can click to draw the polyline. However, there doesn't seem to be a way to end the editing mode. Typically this is a double-click, but that does nothing. I'm left with the polyline in edit mode. Maybe I'm missing a step, but I couldn't find an example in the docs or in the sample code. Here is my button click code: private async void Button_Click(object sender, RoutedEventArgs e) {     var geometry = await MyMapView.SketchEditor.StartAsync(SketchCreationMode.Polyline);     GraphicsOverlay graphicsOverlay;     if (MyMapView.GraphicsOverlays.Count < 1)     {         graphicsOverlay = new GraphicsOverlay();         MyMapView.GraphicsOverlays.Add(graphicsOverlay);     }     else         graphicsOverlay = MyMapView.GraphicsOverlays[0];     var outlineSymbol = new SimpleLineSymbol(SimpleLineSymbolStyle.Solid, Colors.Black, 1.0);     var line = new Graphic(geometry, outlineSymbol);     graphicsOverlay.Graphics.Add(line); } ...
