I think, it is probably a bug because when you create a WMTS layer from 3857 tile matrix set, FullExtent property of created layer still shows coordinates in 2193 wkid. I have tried to project FullExtent to 3857 wkid and then call SetViewpointAsync with projected extent, but it doesn't help. Make a try to create case in Esri support page or call your local distributors to do that. ... View more

Hi, Your WMTS service has 2 Tile Matrix sets with different spatial references: 3857 and 2193. I have succeeded to view your WMTS service with wkid = 2193. I have modified Esri samples code which have Esri.ArcGISRuntime.WPF 300.0.0 package.  I think it must work and with 200.8.0.  Code below: // Define the Uri to the WMTS service. Uri wmtsUri = new Uri("https://data.linz.govt.nz/services;key=5169bef47e224d43a935e4283e2d57a6/wmts/1.0.0/set/4769/WMTSCapabilities.xml"); // Define a new instance of the WMTS service. WmtsService myWmtsService = new WmtsService(wmtsUri); // Load the WMTS service. await myWmtsService.LoadAsync(); // Get the service information (i.e. metadata) about the WMTS service. WmtsServiceInfo myWmtsServiceInfo = myWmtsService.ServiceInfo; // Obtain the read only list of WMTS layer info objects, and select the one with the desired Id value. WmtsLayerInfo info = myWmtsServiceInfo.LayerInfos.Single(l => l.Id == "set-4769"); Map myMap = new Map(SpatialReference.Create(2193)); // Create an instance for the WMTS layer. WmtsLayer myWmtsLayer; // Inspect your layer info matrix names var matrixSet = info.TileMatrixSets.FirstOrDefault(cms => cms.SpatialReference.Wkid == 2193); if (matrixSet != null) { myWmtsLayer = new WmtsLayer(info, matrixSet); } else { myWmtsLayer = new WmtsLayer(info); } var newBasemap = new Basemap(); newBasemap.BaseLayers.Add(myWmtsLayer); myMap.Basemap = newBasemap; // Assign the map to the MapView. MyMapView.Map = myMap; // Zoom the MapView to the geographic boundaries of the WMTS data if (myWmtsLayer.FullExtent != null) { await MyMapView.SetViewpointAsync(new Viewpoint(myWmtsLayer.FullExtent)); }   ...

Hi, Our app initializes MapView.LocationDisplay with default data source on OnPageLoaded event. It works without issues. ... View more

Part of ArcObjects doesn't have analogues in ArcGIS Pro API. Usually geoprocessing tools are used instead. All tools in Trace Network tab use geoprocessing tool Trace with different parameters. Can you do your workflow with standard ArcGIS Pro tools?  ... View more

You can use geoprocessing tool Trace. How to call it from ArcGIS Pro SDK look here. Link to "Trace a trace network" is here. It writes about geoprocessing usage ... View more

Hi, Do you use CustomItemBase directly or implementation of Custom Items derived from the CustomItemBase class? You can find more info about CustomItemBase here. ... View more

Hi, The simplest way is to call your async method from property setter like this: private string _selectedContinent; public string SelectedContinent { get => _selectedContinent; set { if (SetProperty(ref _selectedContinent, value)) { _ = LoadCountriesAsync(value); } } } Continents will be first list, countries will be second list. In the same way you can call async methods from class constructor. You can add more functionality as cancelation token, loading status and etc. internal class WorldViewModel : INotifyPropertyChanged { public ObservableCollection<string> Continents { get; } = new ObservableCollection<string>(); public ObservableCollection<string> Countries { get; } = new ObservableCollection<string>(); private string _selectedContinent; public string SelectedContinent { get => _selectedContinent; set { if (SetProperty(ref _selectedContinent, value)) { // Cancel any in-flight load and start a new one (fire-and-forget) _loadCts?.Cancel(); _loadCts = new CancellationTokenSource(); var token = _loadCts.Token; _ = LoadCountriesAsync(value, token); } } } private string _selectedCountry; public string SelectedCountry { get => _selectedCountry; set => SetProperty(ref _selectedCountry, value); } private bool _isLoading; public bool IsLoading { get => _isLoading; private set => SetProperty(ref _isLoading, value); } private CancellationTokenSource _loadCts; public WorldViewModel() { InitializeContinents(); } private void InitializeContinents() { // Seed continents - replace with real data source if needed Continents.Add("Africa"); Continents.Add("Asia"); Continents.Add("Europe"); Continents.Add("North America"); Continents.Add("South America"); Continents.Add("Oceania"); Continents.Add("Antarctica"); } public async Task LoadCountriesAsync(string continent, CancellationToken cancellationToken = default) { if (string.IsNullOrWhiteSpace(continent)) { Application.Current.Dispatcher.Invoke(() => Countries.Clear()); return; } try { IsLoading = true; // Simulate async IO. Replace with your real async API call (pass cancellationToken). await Task.Delay(500, cancellationToken); // Example data - replace with real result var result = new[] { $"{continent} - Country A", $"{continent} - Country B", $"{continent} - Country C" }; // Update UI collection on UI thread Application.Current.Dispatcher.Invoke(() => { Countries.Clear(); foreach (var c in result) Countries.Add(c); }); } catch (OperationCanceledException) { // expected on cancellation - ignore } catch (Exception ex) { // Adjust logging/error handling to your project's policy System.Diagnostics.Debug.WriteLine($"LoadCountriesAsync error: {ex}"); } finally { IsLoading = false; } } #region INotifyPropertyChanged public event PropertyChangedEventHandler PropertyChanged; protected bool SetProperty<T>(ref T storage, T value, [CallerMemberName] string propertyName = null) { if (Equals(storage, value)) return false; storage = value; PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName)); return true; } #endregion } Don't forget to update lists on the UI thread to avoid threading issues.
