Goal --- Hide Attribute Fields in an attribute table Given a feature class with an attribute table, how would attribute fields be programmatically shown/hidden? Places already researched...

Is there a way to create a BasicRasterLayer and hold it in memory to be used as an intermediate in a raster calculation? The code below is slightly modified from: https://github.com/Esri/arcgis-pro-sdk/wiki/ProSnippets-MapAuthoring#create-a-raster-layer The container needs to be "memory" instead of MapView.Active.Map BasicRasterLayer rasterLayer = null; await QueuedTask.Run(() => { rasterLayer = LayerFactory.Instance.CreateLayer<BasicRasterLayer>(rasterLayerCreationParams, MapView.Active.Map); });   ...

Goal - Create an add-in button that populates a new project with a Folder Connection, a Custom Style and a Custom Tools Lines 3 through 9 below run correctly and were copied from: ProSnippets Content · Esri/arcgis-pro-sdk Wiki (github.com) After modifying the example code to work with a "Style" instead of a "Folder Connection".  An exception is thrown on line 16...  System.NullReferenceException Message=Object reference not set to an instance of an object. Thus, if I read the exception correctly, an object of StyleProjectItem is not instantiated or the return is left as null. Reading through the API documentation...  IProjectItem Interface—ArcGIS Pro The  Overview -> Remarks state, "These classes also follow a convention that includes "ProjectItem" as part of their name" Based upon the stated convention... it appears like StyleProjectItem should be instantiated correctly. protected override async void OnClick() { string folderPath = "C:\\Data"; var folder = await QueuedTask.Run(() => { var itemFolder = ItemFactory.Instance.Create(folderPath) as IProjectItem; return Project.Current.AddItem(itemFolder) ? itemFolder as FolderConnectionProjectItem : null; }); FavoritesManager.Current.AddFavorite(folder); string stylePath = "C:\\Data\\CustomStyles.stylx"; var style = await QueuedTask.Run(() => { var itemStyle = ItemFactory.Instance.Create(stylePath) as IProjectItem; return Project.Current.AddItem(itemStyle) ? itemStyle as StyleProjectItem : null; }); FavoritesManager.Current.AddFavorite(style); string paToolBoxPath = "C:\\Data\\CustomTools.tbx"; var toolBox = await QueuedTask.Run(() => { var itemTool = ItemFactory.Instance.Create(paToolBoxPath) as IProjectItem; return Project.Current.AddItem(itemTool) ? itemTool as GeoprocessingProjectItem : null; }); FavoritesManager.Current.AddFavorite(toolBox); } }   ...

The goal is to format feature class labels using a Text Symbol style item from a custom Style static async Task SetToTextStyle(FeatureLayer featureLayer, string zValueField, string layerName) { string style = "Style1"; string labelStyleName = "Label1"; await QueuedTask.Run(() => { IList<SymbolStyleItem> labelStyleItem = GetLabelStyleFromStyle(Project.Current, style, labelStyleName); var labelStyle = labelStyleItem[0]; // Need to go from a SymbolStyleItem above to a CIMTextSymbol below. CIMTextSymbol textSymbol = SymbolFactory.Instance.ConstructTextSymbol(); CIMSymbolReference symbolReferance = textSymbol.MakeSymbolReference(); CIMLabelClass labelClass = new CIMLabelClass() { ExpressionEngine = LabelExpressionEngine.Arcade, Expression = $"\"pH \" + textformatting.newline + $feature.pH", //probably not correct format TextSymbol = symbolReferance, Visibility = true }; CIMFeatureLayer layerDefinition = featureLayer.GetDefinition() as CIMFeatureLayer; // Code below taken from community sample // This code appears to do the same thing as line 17 List<CIMLabelClass> listLabelClasses = layerDefinition.LabelClasses.ToList(); CIMLabelClass theLabelClass = listLabelClasses.FirstOrDefault(); featureLayer.SetDefinition(layerDefinition); featureLayer.SetLabelVisibility(true); }); } ...

The following error is generated when raster.IsExpanded is tried. How can raster.IsExpanded be used. By the way... I found "IsExpanded" with the CIMViewer.  🙂     RasterLayer raster = null; await QueuedTask.Run(() => { raster = LayerFactory.Instance.CreateLayer<RasterLayer>(rasterLayerCreationParams, map); }); await SetToClassifyColorizer(raster); raster.IsExpanded       ...
