To represent a graphic moving along with mouse cursor, I am adding a point graphic on mouse move and clear it when mouse move is triggered at a new location and a graphic for new location. But the graphics never gets cleared. They stay on map. Here is the code snippet private IDisposable PtGraphic; protected override void OnToolMouseMove(MapViewMouseEventArgs e) { QueuedTask.Run(() => { var pt = ActiveMapView.ClientToMap(e.ClientPoint); ClearGraphic(ref PtGraphic); PtGraphic = AddGraphicToMap(pt, ColorFactory.Instance.RedRGB, 3, SimpleMarkerStyle.Circle); }); base.OnToolMouseMove(e); } private void ClearGraphic(ref IDisposable graphic) { if (graphic != null) graphic.Dispose(); graphic = null; } public static async Task<IDisposable> AddGraphicToMap(Geometry geom, CIMColor color, double size = 1.0, SimpleMarkerStyle markerStyle = SimpleMarkerStyle.Rectangle) { ///Build Symbology return MapView.Active.AddOverlay(geom, symbol); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Am I missing something ?

I am working with ActiveMapViewChanged event as shown in the code snippet. private void SubscribeMapEvents() { ... ActiveMapViewChangedEvent.Subscribe(UpdateUIElements); } private void UpdateUIElements(ActiveMapViewChangedEventArgs obj) { if (obj.IncomingView != null){ ReInitializeUIElements(); } else { ResetUIElements(); } }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Idea is to  update the UI elements with the information from MapView when it changes and reset to initial state when there is no map view. The event triggers correctly when there is no map with IncomingView value as null, and when it updates the event is triggered with active map view's instance in the IncomingView parameter.   Whereas, when I open an attribute table from Table of contents with an active map, this event is triggered twice. First time with IncomingView as null and the second time with the active map view's instance. This behavior is causing an unwanted reset of the controls even when there is an active map present.  ...
