Features from SelectFeaturesAsync and QueryFeaturesAsync are usually not loaded unless you pass QueryFeatureFields.LoadAll parameter in QueryFeaturesAsync so by default it would contain the minimal set of fields that are used for rendering the feature. You can use the following code to test using the service Nagma provided.             try             {                 var layer = MyMapView.Map.OperationalLayers.FirstOrDefault(l => l is FeatureLayer) as FeatureLayer;                 var query = new QueryParameters() { WhereClause = "typdamage = 'Major'" };                 var result = await ((ServiceFeatureTable)layer.FeatureTable).QueryFeaturesAsync(query, QueryFeatureFields.LoadAll);                 foreach (ArcGISFeature f in result.ToArray())                 {                     if (f.LoadStatus != LoadStatus.Loaded)                         await f.LoadAsync();                     // Update attributes here.                 }             }             catch (Exception ex)             {                 MessageBox.Show(ex.Message, ex.GetType().Name);             }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ You can pass the result of this query to SelectFeatures to mark them selected. ...

Hi Mark, Thanks for reporting this issue. I'm able to reproduce the issue with released versions of the API v100.x. While I am not sure what is causing the basemap layers to fail during load, the issue appears fixed in our current version. I can find out for you if there's a workaround for this.  ... View more

I'll answer your question with a sample. The basic idea is related tables all participate in the same map - whether it is another layer or a non-spatial table. You can get to the feature by identify/query. Once you have a feature, query its related features by either specifying specific relationship or getting all regardless of source.         xmlns:esri="http://schemas.esri.com/arcgis/runtime/2013"         Title="MainWindow" Height="350" Width="525">     <Grid>         <Grid.ColumnDefinitions>             <ColumnDefinition />             <ColumnDefinition />         </Grid.ColumnDefinitions>         <esri:MapView x:Name="MyMapView" />         <TreeView x:Name="Result" Grid.Column="1" >             <TreeView.ItemTemplate>                 <HierarchicalDataTemplate  ItemsSource="{Binding}">                     <TextBlock Text="{Binding RelatedTable.TableName}" />                     <HierarchicalDataTemplate.ItemTemplate>                         <DataTemplate>                             <ItemsControl ItemsSource="{Binding Attributes}"                                           Grid.Column="1">                                 <ItemsControl.ItemTemplate>                                     <DataTemplate>                                         <Grid>                                             <Grid.ColumnDefinitions>                                                 <ColumnDefinition />                                                 <ColumnDefinition />                                             </Grid.ColumnDefinitions>                                             <TextBlock Text="{Binding Key, StringFormat={}{0} :}" />                                             <TextBlock Text="{Binding Value, StringFormat={} {0}}"                                                        Grid.Column="1" />                                         </Grid>                                     </DataTemplate>                                 </ItemsControl.ItemTemplate>                             </ItemsControl>                         </DataTemplate>                     </HierarchicalDataTemplate.ItemTemplate>                 </HierarchicalDataTemplate>             </TreeView.ItemTemplate>         </TreeView>     </Grid>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍             MyMapView.GeoViewTapped += MyMapView_GeoViewTapped;             MyMapView.Map = new Map(Basemap.CreateTopographic());             MyMapView.Map.OperationalLayers.Add(new FeatureLayer(new Uri("https://services2.arcgis.com/ZQgQTuoyBrtmoGdP/ArcGIS/rest/services/AlaskaNationalParksPreservesSpecies_List/FeatureServer/1")));             MyMapView.Map.OperationalLayers.Add(new FeatureLayer(new Uri("https://services2.arcgis.com/ZQgQTuoyBrtmoGdP/ArcGIS/rest/services/AlaskaNationalParksPreservesSpecies_List/FeatureServer/0")));             MyMapView.Map.Tables.Add(new ServiceFeatureTable(new Uri("https://services2.arcgis.com/ZQgQTuoyBrtmoGdP/ArcGIS/rest/services/AlaskaNationalParksPreservesSpecies_List/FeatureServer/2")));             MyMapView.Map.InitialViewpoint = new Viewpoint(new Envelope(-17677159.6926513, 7932123.08666798, -16355129.8191665, 9451936.95697339, SpatialReferences.WebMercator));         }         private async void MyMapView_GeoViewTapped(object sender, GeoViewInputEventArgs e)         {             var result = await MyMapView.IdentifyLayersAsync(e.Position, 2, false);             foreach (var identifyResult in result)             {                 if (identifyResult.LayerContent is FeatureLayer && ((FeatureLayer)identifyResult.LayerContent).FeatureTable is ArcGISFeatureTable)                 {                     var table = (ArcGISFeatureTable)((FeatureLayer)identifyResult.LayerContent).FeatureTable;                     foreach (ArcGISFeature feature in identifyResult.GeoElements)                     {                         var queryResults = await table.QueryRelatedFeaturesAsync(feature);                                                Result.ItemsSource = queryResults.ToArray();                     }                 }             }         }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...
