The behavior as described is exactly what I see.  I had a WebMap with labeling defined in the WebMap but not on the service.  When I load the WebMap in Runtime (100.4) no labels appear.  I just went back and added labels into the Map in Pro and republished the service, the labels now show-up.  Even if the labels are turned off in the WebMap it honors the labeling defined on the service.

Just noticed the WebMap labels are ignored.  Seems a pretty big deficiency to me.  It gives you no way to have different label configurations if they need to be done at the service level  ... View more

A different question related to custom LocationDataSource.  I have a DataSource that receives data from a Bluetooth source.  It all seems to work as expected except for one critical aspect, when UpdateLocation is called it does not seem to actually fire LocationChanged.  I have other DataSources which work in basically the same manner and the event is being fired as expected, however, in this one case nothing happens the event handler never receives anything and you never see the location on the map Any thoughts?

Thanks.  Dang I wasted a lot of time on that ... View more

This does work if I get rid of IWA and just use portal authentication.  But I cannot believe we cannot query a FeatureLayer in python if using IWA.   ... View more

Not sure if the Runtime team will like this approach, but the .geodatabase is just a SqLite database.  If you just need to get the values to populate a list you could use the System.Data.SQLite API.  I'm sure it will be a LOT faster than trying to query the table and find the values.  Something along these lines string connectioString = $"Data Source={filename}"; using (SQLiteConnection connection = new SQLiteConnection(connectioString)) {      connection.Open();      string query = "Select Distinct(fieldname)from thetable";      SQLiteCommand command = new SQLiteCommand(query, connection);      var reader = command.ExecuteReader();      while ( reader.Read() )      {         uniqueValuesList.Add(reader[fieldname].ToString()});      } }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ We do some direct queries of the table to get information about the replica in the GDB_Items table.  We do these queries before the table is open in the map so I am not sure if there would be an issue if you were doing when the .geodatabases where loaded into the map ...

I know this discussion is old and maybe has been beaten like the proverbial dead horse, however, as we are making some large scale changes to our application I thought I would revisit the architecture of how identify is being done. First to explain our application architecture, we are using a module application built on top of the prism framework.  Unity is used as a DI framework.  Modules are discovered at run time so different application configurations can be deployed based on what modules are present on a system.  While it is not required to use this approach, some MVVM framework that provides robust event aggregation is required.  Something like MVVM Light would also fit the bill.  I don't really understand trying to build a large scale application using MVVM without a good framework to support better command and event patterns.   I will also continue to argue that the MapView does need to be exposed (and also that the provided sample is in actuality doing just that).  One place dependent on this is the Table of Contents control.  Because this is binds to the MapView and is in its own module there has to be a way to expose the MapView to the rest of the application or at minimum outside of the UserControl containing the MapView.  All that said...As was pointed out and shown in the example the Controller approach is a really nice clean way to expose the MapView.  This basically uses the same approach as in the example except it just is used to expose the MapView. So as in the example, but with a little renaming. public class MapViewExtensions : DependencyObject {      /// <summary>      /// Creates a MapViewController property      /// </summary>      public static readonly DependencyProperty MapViewControllerProperty = DependencyProperty.RegisterAttached(           nameof(MapViewController),           typeof(MapViewController),           typeof(MapViewExtensions),           new PropertyMetadata(null, OnMapViewControllerChanged));      /// <summary>      /// Invoked when the MapViewController's value has changed      /// </summary>      private static void OnMapViewControllerChanged(DependencyObject dependency, DependencyPropertyChangedEventArgs args)      {           if (args.NewValue is MapViewController)           {                ((MapViewController)args.NewValue).MapView = dependency as MapView;           }      }      /// <summary>      /// MapViewController getter method      /// </summary>      public static MapViewController GetMapViewController(DependencyObject d)      {           return (d as MapView)?.GetValue(MapViewControllerProperty) as MapViewController;      }      /// <summary>      /// MapViewController setter method      /// </summary>      public static void SetMapViewController(DependencyObject d, MapViewController value)      {           (d as MapView)?.SetValue(MapViewControllerProperty, value);      } }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ And the simplified controller public class MapViewController : DependencyObject {      /// <summary>      /// Gets or sets the MapView on which to perform identify operations      /// </summary>      public virtual MapView MapView { get; set; } }‍‍‍‍‍‍‍ This gets to the fun part.  Identify is done using a TriggerAction which can then be attached to the MapView.  Also something to note is that our application identifies all the layers in the map, not just a single or multiple pre-defined layer .  Here is where the EventAggregator comes in, this is set as a DependencyProperty so it can be bound from the ViewModel.  The Map is also bound to the TriggerAction.  /// <summary> /// Custom action fired on GeoviewTappedEvent.  Either bind a Layer collection /// of Layers to be identified or bind Map if want to identify all visible layers /// </summary> public class IndentifyAction : TriggerAction<MapView> {      private bool _doubleTapped = false;      protected override async void Invoke(object parameter)      {           await Task.Delay(250);           if ( _doubleTapped )           {                _doubleTapped = false;                return;           }           if (!(AssociatedObject is MapView mapView)) return;           if (!(parameter is GeoViewInputEventArgs args)) return;           double tolerance = 10d;           if ( Map != null )           {                var identifyLayerResults = new List<IdentifyLayerResult>();                Mouse.OverrideCursor = Cursors.Wait;                for (int i = Map.OperationalLayers.Count - 1; i >= 0; i--)                {                     FeatureLayer mapLayer = Map.OperationalLayers[i] as FeatureLayer;                     if (mapLayer?.PopupDefinition == null || mapLayer.IsVisible == false ) continue;                     if ( mapLayer.FeatureTable.TableName == null ) continue;                     var result = await mapView.IdentifyLayerAsync(mapLayer, args.Position, tolerance, false, 10);                     identifyLayerResults.Add(result);                }                Mouse.OverrideCursor = Cursors.Arrow;                EventAggregator.GetEvent<IdentifyEvent>().Publish(new IdentifyEventArgs(args.Location, identifyLayerResults));                return;           }           if (Layers != null)           {                //TODO           }      }      protected override void OnAttached()      {           base.OnAttached();           if (!(AssociatedObject is MapView mapView)) return;           //This seems silly to me, but a GeoViewDoubleTapped fires both a tapped and a double tapped.           //This indicates was double tapped           mapView.GeoViewDoubleTapped += (s, e) => { _doubleTapped = true; };      }      //Bound Layers to be identified.      public static readonly DependencyProperty LayersProperty = DependencyProperty.Register(           "Layers", typeof(IEnumerable<Layer>), typeof(IndentifyAction), new PropertyMetadata(default(IEnumerable<Layer>)));      public IEnumerable<Layer> Layers      {           get => (IEnumerable<Layer>) GetValue(LayersProperty);           set => SetValue(LayersProperty, value);      }        public static readonly DependencyProperty MapProperty = DependencyProperty.Register(           "Map", typeof(Map), typeof(IndentifyAction), new PropertyMetadata(default(Map)));      public Map Map      {           get => (Map) GetValue(MapProperty);           set => SetValue(MapProperty, value);      }      public static readonly DependencyProperty EventAggregatorProperty = DependencyProperty.Register(           "EventAggregator", typeof(IEventAggregator), typeof(IndentifyAction), new PropertyMetadata(default(IEventAggregator)));      public IEventAggregator EventAggregator      {           get => (IEventAggregator) GetValue(EventAggregatorProperty);           set => SetValue(EventAggregatorProperty, value);      }    }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ The Xaml for the View containing the MapView looks like this. <Grid>      <esri:MapView x:Name="MapView" Map="{Binding Map}"                       framework:MapViewExtensions.MapViewController="{Binding MapViewController}">           <esri:MapView.Resources>                <Style TargetType="esri:Callout">                     <Setter Property="BorderBrush" Value="Transparent" />                     <Setter Property="BorderThickness" Value="0" />                     <Setter Property="Background" Value="{DynamicResource ApplicationBackgroundColorLight}"/>                     <Setter Property="Padding" Value="0"/>                </Style>           </esri:MapView.Resources>           <i:Interaction.Triggers>                <i:EventTrigger EventName="GeoViewTapped">                     <identify:IndentifyAction Map="{Binding Map}" EventAggregator="{Binding EventAggregator}"/>                </i:EventTrigger>           </i:Interaction.Triggers>      </esri:MapView> </Grid>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ That pretty much does the trick.  At this point all that is needed is someone to listen for the event and show a popup if desired.  There is one kind of annoying thing I did do and that is use the wait cursor.  This is not needed and because this is async method if there is not a listener the identify just happens on a background thread and the user is none the wiser.  That does need some reconsideration. There is now a module specific to identify.  It has the Controller injected through the constructor public PopupViewModel(MapViewController controller) {      PopupPages = new ObservableCollection<PopupPage>();      _controller = controller;      Height = 200;      Width = 370; }‍‍‍‍‍‍‍‍ Subscribe to the event EventAggregator.GetEvent<IdentifyEvent>().Subscribe(OnIdentify);‍ And respond to the event private void OnIdentify(IdentifyEventArgs args) {      PopupPages.Clear();      PopupPageCount = 0;      CurrentFeatures.Clear();      //How to be MVVM and still have a custom popup?  Not sure this fits the bill...      //Stuff my popup view in a hidden region      UIElement popupView = (UIElement)RegionManager.Regions[RegionNames.PopupRegion].Views.FirstOrDefault();      Location = args.Location;      if ( popupView == null ) return;      foreach (var featureLayerResult in args.IdentifyLayerLayerResults)      {           foreach (var feature in featureLayerResult.GeoElements.OfType<Feature>())           {                if ( featureLayerResult.LayerContent is FeatureLayer featureLayer )                {                     AddPopupPage(feature, featureLayer);                }           }      }      _controller.MapView.ShowCalloutAt(Location, popupView); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ And here one could say the MVVM is blown-up.  A custom control is used for the popup and this view does come into the ViewModel in order to be shown.  If a standard CalloutDefinition was used this would not be required.  In the back recesses of my mind I am trying to come up with a way you could do this with Navigation but that will take a lot more to figure out. ...
