I realize this is late help, but maybe it will help others. You need to check IsNull first on desired field: if (!row.IsNull(fieldName)) { var value = row.GetString(fieldName); return value; } It applies to all Get* methods. ... View more

I am facing similar issues on 200.7 and .NET 9 MAUI. Last of them is with ArcGIS Runtime: Esri.ArcGISRuntime.ArcGISRuntimeException: Invalid argument: Scale is less than or equal to zero. void ArcGISException.HandleCoreError(CoreError error, bool throwException) Assembly: Esri.ArcGISRuntime Version: 200.7.0.0 PublicKeyToken: xxxxxxxxxxxxxxxx void Interop.CheckError(IntPtr errorHandle, bool throwOnFailure, GCHandle wrapperHandle) void CoreMapView.InteractionZoomToScale(double scale, CoreCoordinate2D screenPoint) bool MapView.OnGeoViewManipulationDelta(PointF origin, PointF screenLocation, double translateX, double translateY, double scale, double rotation, bool isFlick, DeviceIndependentPointingDevice device) bool UserInteractionHandler.OnManipulationDelta(PointF origin, PointF screenLocation, double translateX, double translateY, double scale, double rotation, bool isFlick, DeviceIndependentPointingDevice device) bool AndroidDeviceInteractionHandler.OnTouchEvent(MotionEvent ev) GeoView(CoreGeoView geoView, Context context, IAttributeSet attr)+(object s, TouchEventArgs e) => { } Called from: bool IOnTouchListenerImplementor.OnTouch(View v, MotionEvent e) Application life cycle: Exception - This event error 09:33:30.000 AM Esri.ArcGISRuntime.ArcGISRuntimeException: Invalid argument: Scale is less than or equal to zero.

I have found workaround for map freezing where suggests handle OnResume() event. Would it be helpful to make some delay inside OnResume()? Do you have some experience of handling application resume issues? ... View more

Hi, Have you seen ConnerPearce suggestion here? ... View more

Hi, Try to change newSubpane parameter value to true: Geoprocessing.OpenToolDialog(scriptPath, null, null, newSubPane: true); ... View more

Custom renderers could help you. The custom renderer approach allows you to use native controls and their features. By writing custom renderers, you can capture native touch events. ... View more

There is possibility to use GeometryEditor which works with magnifier, but it has some requirements. More info in that thread. ... View more

Hi, You can switch off magnifier and implement your workflow on GeoViewHolding. Code below: // In MainPage constructor mapView.InteractionOptions = new MapViewInteractionOptions() { IsMagnifierEnabled = false, // Disable magnifier. }; ... View more

Hi, There is one sample project for VB in Esri Community ArcGIS Pro Samples. Solution is here. Try code below for your functionality: Try 'TRY TO GET THE CENTER SCREEN LOCATION FROM THE ACTIVE VIEW, JUST SHOW THE FORM ON ERROR Dim areaOfInterest = MapView.Active.Extent Dim pPoint As MapPoint pPoint = MapPointBuilderEx.CreateMapPoint((areaOfInterest.XMax - areaOfInterest.XMin) / 2 + areaOfInterest.XMin, (areaOfInterest.YMax - areaOfInterest.YMin) / 2 + areaOfInterest.YMin, MapView.Active.Map.SpatialReference) Dim pGeoCoordSystem As SpatialReference Dim pProjCoordSystem As SpatialReference Dim pGeoTrans As ProjectionTransformation pGeoCoordSystem = SpatialReferenceBuilder.CreateSpatialReference(SpatialReferences.WGS84) pProjCoordSystem = SpatialReferenceBuilder.CreateSpatialReference(102633) pGeoTrans = ProjectionTransformation.Create(pProjCoordSystem, pGeoCoordSystem) Dim pProjectedPoint As MapPoint pProjectedPoint = CType(GeometryEngine.Instance.ProjectEx(pPoint, pGeoTrans), MapPoint) Console.WriteLine(CStr(pProjectedPoint.Y)) Console.WriteLine(CStr(pProjectedPoint.X)) Catch ex As Exception 'DO NOTHING End Try As I understand your map spatial reference is esriSRProjCS_NAD1983SPCS_AK3FT. So, instead of creating pProjCoordSystem you can use Map spatial reference ... View more

Hi, @Jeff-Reinhart Look at the DatastoresDefinitionsAndDatasets sample. DataPath property has two-way binding. DockPane implements INotifyPropertyChanged. OnPropertyChanged is implemented  inside  SetProperty(ref _dataPath, value, () => DataPath); You can change it to expanded form: _dataPath = value; OnPropertyChanged();   ... View more

I would recommend for issues with geoprocessing parameters use ExecuteToolAsync method with GPToolExecuteEventHandler parameter. Sample you can find in documentation here, or in Community samples. ... View more
