Does the ArcGis Pro SDK for .Net expose AtrributeRules? I have found some classes in ArcGIS.Core.Data but they only deal with evaluating existing rules and AttributeRule Errors, but nothing on enumerating or examining what those existing rules are. Haven't come across anything in snippets or samples either. ... View more

I want to be able to open (activate) a MapPane with a specific map if it exists, or create it if it doesn't but can't figure out how to accomplish this. Logically, I can get all the MapPanes with this: var mapProjItems = Project.Current.GetItems<MapProjectItem>(); Each of the MapPanes in there *should* have a map, and if I iterate through there, I can  activate the pane if the map's name is the one I want, or create a new one if it is not found. The problem is that only the MapPane that is currently active has a map, for all the others  the map property is null. There is a Pro Snippet called "Get the Unique List of Maps From the Map Panes" and it crashes because of the same problem: public static IReadOnlyList<Map> GetMapsFromMapPanes() { //Gets the unique list of Maps from all the MapPanes. //Note: The list of maps retrieved from the MapPanes //maybe less than the total number of Maps in the project. //It depends on what maps the user has actually opened. var mapPanes = ProApp.Panes.OfType<IMapPane>() .GroupBy((mp) => mp.MapView.Map.URI).Select(grp => grp.FirstOrDefault()); List<Map> uniqueMaps = new List<Map>(); foreach (var pane in mapPanes) uniqueMaps.Add(pane.MapView.Map); return uniqueMaps; }   There is another snippet called "Find a map within a project and open it", but it always creates a new MapPane (so then you have two with the same name and map) because of the same problem. And there is also the MapProjectItem.OpenMapPane() method, but it too creates a new MapPane. This should be so simple to do... ... View more

In an addin i'm creating there's a button that will add a raster layer to my map based on a selected value in a listbox. The code is simple and works fine: the new layer appears in the TOC and the image appears on the map, but curiously all visibility checkboxes on layers in the TOC become greyed out for a while. After a minute or so, they become enabled again. I'm guessing something is going on in a background thread that is setting the visibility checkboxes to disabled while it is doing whatever it is doing. The question is what is it doing?  The images are around 10mb each and georeferenced. private async void cmd_ButtonAdd_Click(Object sender) { Layer pImgLay; string url = selectedObliqueVal; url = m_imgPath + m_Isle + m_imgFolder + "A" + url.Substring(1, 1) + @"\" + url + ".jpg"; if (!System.IO.File.Exists(url)) { MessageBox.Show("File does not exist:\r\n" + url); return; } pImgLay = await QueuedTask.Run(() => { return LayerFactory.Instance.CreateLayer(new Uri(url), MapView.Active.Map); }); _addedImages.Add(url); //MessageBox.Show("Add"); }   ...

I created some ArcObjects code that creates a geoprocessing tool that creates a featureclass from some input files. The code creates a GP tool that works as it should, except for one problem: the GP parameter for the input files accepts all files when it is supposed to only accept files with the extension .jxl or .xls. There is no documentation on how to do this, but below is the code snippet of what I wrote to create the input file parameter.  I've also converted the tool to a Python tool (which has much better documentation) and it does filter input files to just the allowed ones. I assume the underlying objects are the same for the .Net SDK as for ArcPy, so there should be a way to get the .net authored tool to work as well. I also looked for clues in the Pro SDK, but came up with nothing since Pro doesn't even support creating GP tools with .net.
