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.

Hi, Try to change Map spatial reference to WGS84 // Create a map MyMapView.Map = new Map(SpatialReferences.Wgs84) { // Set initial view point in WGS84 //InitialViewpoint = new Viewpoint(55.610000, -5.200346, 100000) }; ... View more

Hi, It would be nice to see piece of your code. How do you use  CreateRow? Are you using editOperation.Callback as in sample here? Are you calling context invalidate for feature: context.Invalidate(feature); ... View more

I saw another thread with your comment about one second for animation. I could say that car already passed crossroad, but current location symbol is about 5-10 meters before crossroad on speed 50 km/h. Driver will always miss required crossroad to change direction if look to map. Current location symbol moves like a frog trying to catch real car position: gap, no gap, gap and so on. On asynchronous LocationChanged event we make redrawing of rest route, checking of speed limit, rerouting needs and etc. I would like to see at first moved current location symbol then get LocationChanged event (like WYSIWYG). To see real car position is more important thing than others. ... View more

Hi, When you trying to publish web tool code, ArcGIS makes revision of your code and makes some changes in it. The mangling happens because ArcGIS is trying to do some kind of validation of "path-like strings" against what data sources are registered on ArcGIS Server. Check for differences with your original code. It is recommended all paths make as parameters for tool. Then you can setup these parameters as constants and don't need to specify each time you run tool. ... View more
