Hi Lesley When you change the underlying datasource for a raster (or any feature layer for that matter), you will have also change the Colorizer (Change the renderer for a feature layer). This will update the Legend in the TOC. So it is a 2 step process: 1. Change the datasource using the ReplaceDataSource method. 2. Then apply the colorizer suitable for the new data. This is the code snippet I used: var rasterLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<RasterLayer>().FirstOrDefault(); QueuedTask.Run(async () => { using (Geodatabase geodatabase = new Geodatabase(new FileGeodatabaseConnectionPath(new Uri(@"\\Path-to-Data\raster.gdb")))) { using (Dataset dataset = geodatabase.OpenDataset<RasterDataset>("elevation")) { rasterLayer.ReplaceDataSource(dataset); // Check if the Stretch colorizer can be applied to the raster layer. if (rasterLayer.GetApplicableColorizers().Contains(RasterColorizerType.StretchColorizer)) { // Create a new Stretch Colorizer Definition using the default constructor. StretchColorizerDefinition stretchColorizerDef_default = new StretchColorizerDefinition(); // Create a new Stretch colorizer using the colorizer definition created above. CIMRasterStretchColorizer newStretchColorizer_default = await rasterLayer.CreateColorizerAsync(stretchColorizerDef_default) as CIMRasterStretchColorizer; // Set the new colorizer on the raster layer. rasterLayer.SetColorizer(newStretchColorizer_default); } } } });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

Hi, By default, any new UI elements you add get on to the "Add-in" tab. This is controlled by the "appearsOnAddintab" attribute in your DAML.  The add-in template does this to provide you with a quick and convenient way to get your controls on to Pro's ribbon.  So if you want to create a new tab to host your controls, do the following: 1. In your add-in's config.daml, set the apprearsOnAddIntab attribute to false in the group element that hosts your buttons. <group id="LayerDocConstructor_Group1" caption="Group 1" appearsOnAddInTab="false">‍ 2. Make a new Tab and host your group in that tab. <tabs> <tab id="LayerDocConstructor_Tab1" caption="New Tab"> <group refID="LayerDocConstructor_Group1"/> </tab> </tabs>‍‍‍‍‍ Thanks Uma ... View more

Hi, I would suggest that you should use ActivePaneChangedEvent instead. The type of pane returned when the Active Pane changes will tell you if it is a Map Pane or a Table. It will be MapPaneViewModel for an Active Map or TablePaneViewModel for a Table.  Code snippet: //Subscribe to event ArcGIS.Desktop.Framework.Events.ActivePaneChangedEvent.Subscribe(OnActivePaneChanged); private void OnActivePaneChanged(PaneEventArgs obj) { if (obj.IncomingPane != null) { System.Diagnostics.Debug.WriteLine($"Debug Message. GetTypeName: {obj.IncomingPane.GetType().Name}"); } }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ A little background on the behavior you are seeing with ActiveMapViewChanged event - When you display the attribute table of a feature layer in the Active map, the IncomingView is first null (which is correct). The attribute table pane then becomes the active pane. But when the attribute table pane is active, the TOC that lists the layers needs to know the “context” of which map it needs to use. So the Attribute table pane that is currently active, “impersonates” the Map Pane. Hence the event gets triggered again and the Incoming View is now the “Map” associated with the attribute table.

Hi, The best way to get the bounding envelope of the graphic element is to: * Construct a polygon using the X, Y, Width and Height of the element. * Rotate the polygon with the element's rotation angle. * Use the "Extent" property on the polygon to get the "envelope" extent.   Here is some code that does this - QueuedTask.Run( () => { var layout = Project.Current.GetItems<LayoutProjectItem>().FirstOrDefault().GetLayout(); var element = layout.Elements.OfType<GraphicElement>().FirstOrDefault(); if (element == null) return; //Get the element's X, Y, Width and height var x = element.GetX(); var y = element.GetY(); var width = element.GetWidth(); var height = element.GetHeight(); //Create a polygon using the Graphic elements X, Y, Width and Height. MapPoint pt1 = MapPointBuilder.CreateMapPoint(x, y); //Anchor pt - lower left MapPoint pt2 = MapPointBuilder.CreateMapPoint(x + width, y); //lower right MapPoint pt3 = MapPointBuilder.CreateMapPoint(x + width, y + height );//upper right MapPoint pt4 = MapPointBuilder.CreateMapPoint(x, y + height);//upper left List<MapPoint> list = new List<MapPoint>() { pt1, pt2, pt3, pt4 }; Polygon polygon = PolygonBuilder.CreatePolygon(list, null); //Rotate the polygon by the same angle the graphic element is rotated by var polygonRotate = GeometryEngine.Instance.Rotate(polygon, pt1, element.GetRotation() * (Math.PI / 180)) as Polygon; //Angle should be in radians. //Use polygonRotate to get the bounds of the rotated text element System.Diagnostics.Debug.WriteLine($"Width: {polygonRotate.Extent.Width}, Height: {polygonRotate.Extent.Height}"); //Create another graphic element that envelops the original element Envelope env = polygonRotate.Extent; CIMStroke lineStroke = SymbolFactory.Instance.ConstructStroke(ColorFactory.Instance.BlackRGB, 1, SimpleLineStyle.DashDotDot); LayoutElementFactory.Instance.CreatePolygonGraphicElement(layout, env, SymbolFactory.Instance.ConstructPolygonSymbol(ColorFactory.Instance.RedRGB, SimpleFillStyle.Null, lineStroke)); });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...
