Annotation layer not showing

Paul_K — Thu, 01 Sep 2022 21:53:28 GMT

Using ArcGISRuntime 100.15 and based on the ESRI Display Annotation Layer sample I have an app with the following code for displaying an annotation layer:

The 'Loaded' event fires and indicates that the annotation layer loaded without error, but it is not displaying on the map. When loaded, the SublayerContents property is empty, which seems suspicious since the annotation layer does have sublayers.

The annotation layer displays properly in ArcGIS Pro and in the online map viewer.

Any ideas on what might be wrong or what to look at next?

What does the MapView LayerViewStateChanged event report?

Thanks for that suggestion. I added event handling code as follows:

MyMapView.Map = new Map(BasemapStyle.ArcGISStreets); MyMapView.LayerViewStateChanged += (sender, args) => { Trace.WriteLine($"Layer:'{args.Layer.Name}' Status:{args.LayerViewState.Status}"); Trace.WriteIf(args.LayerViewState.Error is not null, $"\tError:{args.LayerViewState.Error}\n"); };

And, here's the output:

Layer:'World_Basemap_v2' Status:NotVisible
Layer:'' Status:Loading
Layer:'World_Basemap_v2' Status:Active
GasGenericAnno loaded; visible: True; IsVisibleAtScale: True
Layer:'GasGenericAnno' Status:NotVisible
Layer:'GasGenericAnno' Status:Active
