Hi, I am trying to add 3 layers to a group layer in a specific index order. I use the FeatureLayerCreationParams object with the LayerFactory.Instance.CreateLayer() function - but when I look at the results in the TOC - the layers have come in a random order and not the order I specified. This was working fine in 2.x but since I have moved to 3.x this code does not seem to work - I'm not sure what I can do but I need to fix the problem urgently. Here is the code I use (I pass in my object called "layer", which holds the index information to pass on):     await QueuedTask.Run(() => { Item stagingLayer = ItemFactory.Instance.Create(AgolId, ItemFactory.ItemType.PortalItem); if (LayerFactory.Instance.CanCreateLayerFrom(stagingLayer)) { var featureCreateParams = new FeatureLayerCreationParams(stagingLayer) { IsVisible = layer.Visible, MapMemberIndex = layer.LayerOrder, //Even this does NOT fix the issue MapMemberPosition = MapMemberPosition.Index, Name = layer.Name }; LayerFactory.Instance.CreateLayer<FeatureLayer>(featureCreateParams, groupLayer); } });         ...

I have a maptool where I just place a marker on a map. Nothing else, no other business logic. The marker is placed fine, however - when you look at the debug the amount of exceptions thrown from ArcGIS.Dektop.Mapping.dll is concerning. What is going on here, should this be happening?   Here is my simple code: internal class FooTool : MapTool { private IDisposable _graphic = null; public FooTool() { IsSketchTool = true; SketchType = SketchGeometryType.Point; SketchOutputMode = SketchOutputMode.Map; } protected override async Task<bool> OnSketchCompleteAsync(ArcGIS.Core.Geometry.Geometry geometry) { try { MapPoint mapPoint = (MapPoint)geometry; await QueuedTask.Run(() => { var mapView = MapView.Active; //Show marker if (_graphic != null) { _graphic.Dispose(); } _graphic = mapView.AddOverlay(mapPoint, SymbolFactory.Instance.ConstructPointSymbol(ColorFactory.Instance.BlueRGB, 14, SimpleMarkerStyle.Pushpin).MakeSymbolReference()); }); } catch (ArgumentException ae) { ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show(ae.Message, "Tool error"); } catch (Exception ex) { Log.Error(ex); } return true; } }       ...

Hi, We, as a company are facing a serious limitation which is having an impact on the add-in software we supply to our customers. We need to be able to search AGOL for items (Layers) that exceed the 10000 limit - we have around 33,000 items we want to return. This is my code which hits the hard limit of 10,000 - it uses pagination. private static async Task<HashSet<AgolLayer>> GetLayersFromAGOL(string search) { var portal = ArcGISPortalManager.Current.GetActivePortal(); HashSet<AgolLayer> agolLayers = new HashSet<AgolLayer>(new AgolIdComparer()); if (portal.IsSignedOn()) { var query = PortalQueryParameters.CreateForItemsOfTypes(new List<PortalItemType>() { PortalItemType.Layer }, "", Properties.Settings.Default.CurrentGroupId, search); query.Limit = 100; query.Query = query.Query + "&sortField=modified&sortOrder=desc"; //Loop until done var portalItems = new List<PortalItem>(); while (query != null) { //run the search PortalQueryResultSet<PortalItem> results = await portal.SearchForContentAsync(query); portalItems.AddRange(results.Results); totalResultsCount = results.TotalResultsCount; query = results.NextQueryParameters; } foreach (var pi in portalItems) { AgolLayer agolLayer = new AgolLayer(pi); agolLayers.Add(agolLayer); } } return agolLayers; } Is there a way around this limitation?   Some links (below) back the findings I am referring to: https://developers.arcgis.com/rest/users-groups-and-items/considerations-and-limitations.htm   ...

Hi, I'm trying to go through each layer in the TOC and do get the alias name of the layer then do something that name. In order to this - I have a recursive method that loops - however you need to await QueuedTask.Run() the call to get information about an alias in layer - and in a recursive function something weird is happening - as this only gets called once and never breaks into that Queued Task code block again.   Something is happening here thats a bit beyond me when it gets to asynchronous programming - can anyone help me find a way to get this recursive function to work properly?     //calling code: var map = MapView.Active.Map; foreach (var item in map.Layers) { await RecurseTocLayers(item); } private async Task RecurseTocLayers(Layer layer) { if (layer is BasicFeatureLayer) { FeatureLayer featureLayer = layer as FeatureLayer; //THIS ONLY GETS CALLED ONCE - THEN NEVER AGAIN! await QueuedTask.Run(() => { var table = featureLayer.GetTable(); TableDefinition tableDefinition = table.GetDefinition(); string alias = tableDefinition.GetAliasName(); //do something here with alias name.....e.g. System.Diagnostics.Debug.WriteLine($"The alias name is: {alias}"); }); } if (layer is GroupLayer) { //do something here with GroupLayer, then.... GroupLayer groupLayer = (GroupLayer)layer; foreach (var child in groupLayer.Layers) { await RecurseTocLayers(child); } } }     ASDFDSAF ... View more

This should be simple, however I can't seem to find how you can get the alias name of a featureclass. I am going though the layers in the TOC, I think they are FeatureLayer type when you are looping, but no obvious way to find the alias.         ... View more
