BackgroundTask is 2.6 fyi. In the meanwhile u can try something like this - note: u cant use a Task directly because Tasks are MTA. Anyway, make sure u read all the fine print. Dont run anything off the MCT that alters the application.    //http://stackoverflow.com/questions/16720496/set-apartmentstate-on-a-task internal class BackgroundTaskTemp { public static Task Run(TaskPriority priority, Action action) { var tcs = new TaskCompletionSource<bool>(); Thread thread = new Thread(() => { try { action(); tcs.SetResult(true); } catch (Exception e) { tcs.SetException(e); } }); thread.Priority = FromTaskPriority(priority); thread.SetApartmentState(ApartmentState.STA); thread.Start(); return tcs.Task; } public static Task<T> Run<T>(TaskPriority priority, Func<T> func) { var tcs = new TaskCompletionSource<T>(); Thread thread = new Thread(() => { try { tcs.SetResult(func()); } catch (Exception e) { tcs.SetException(e); } }); thread.Priority = FromTaskPriority(priority); thread.SetApartmentState(ApartmentState.STA); thread.Start(); return tcs.Task; } private static ThreadPriority FromTaskPriority(TaskPriority priority) { if (priority == TaskPriority.high) return ThreadPriority.Highest; if (priority == TaskPriority.single) throw new InvalidOperationException("Sorry, no can do - wait for 2.6 and the proper BackgroundTask"); else return ThreadPriority.Normal; } } }   usage:   var layout = LayoutView.Active?.Layout; if (layout == null) return; await QueuedTask.Run(() => { ... //export on the background thread //ArcGIS.Core.Threading.Tasks.BackgroundTask.Run( //ArcGIS.Core.Threading.Tasks.TaskPriority.normal, // () => layout.Export(pdf), //ArcGIS.Core.Threading.Tasks.BackgroundProgressor.None); BackgroundTaskTemp.Run( ArcGIS.Core.Threading.Tasks.TaskPriority.normal, () => layout.Export(pdf)); ... ... });   ...

export looks like a good candidate for the BackgroundTask so u might want to consider using _that_ rather than the QueuedTask. Obviously switching threads doesnt make something _quicker_ but it will free up the QueuedTask to allow u to get on with your other business.   var layout = LayoutView.Active?.Layout; if (layout == null) return; await QueuedTask.Run(() => { var def = layout.GetDefinition() as CIMLayout; //Make changes... //Commit changes layout.SetDefinition(def); //Tee-up export - add-in is responsible for checking //validity of OutputFileName var pdf = new PDFFormat() { Resolution = 300, OutputFileName = $"C:\\temp\\{layout.Name}.pdf" }; //Export on a background thread ArcGIS.Core.Threading.Tasks.BackgroundTask.Run( ArcGIS.Core.Threading.Tasks.TaskPriority.normal, () => layout.Export(pdf), ArcGIS.Core.Threading.Tasks.BackgroundProgressor.None); //We are still on the QueuedTask here... //continue doing work but be mindful that your layout may //still be exporting ... });   U can read more about it here: https://github.com/esri/arcgis-pro-sdk/wiki/ProConcepts-Asynchronous-Programming-in-ArcGIS-Pro#using-backgroundtask . The most important thing to remember when using BackgroundTask is to never change application state_. That is what the CIM thread, or MCT as we call it is for, and that is accessed via QueuedTask.   ... View more

do u mind providing your usercontrol xaml or some xaml that provides a repro and I'll forward to the UI team ... View more

This is what I see in the ADMapping.daml. <splitButton id="esri_mapping_locateSplitButton" keytip="L" extendedCaption="Search for addresses"> <button refID="esri_mapping_showLocateDockPane"/> <gallery refID="esri_mapping_locateGallery"/> </splitButton>   So, I think if u reference the locateSplitButton rather than the showLocateDockPane u will be good to go.     ...

looking in the ADMapping.daml I see this: <customControl id="esri_mapping_downloadMap" caption="Download Map" className="ArcGIS.Desktop.Internal.Mapping.Ribbon.DownloadMap" disableIfBusy="true" showHelp="true" staysOpenOnClick="true" isDropDown="true" ...> <content className="ArcGIS.Desktop.Internal.Mapping.Ribbon.DownloadMapControl" /> ... </customControl>   Note the staysOpenOnClick and IsDropDown attributes. I think those are what you are after. You can find the ADMapping.daml here: <your Pro install location>/bin/Extensions/Mapping and here: https://github.com/Esri/arcgis-pro-sdk/wiki/DAML-ID-Reference-ADMapping.daml  ... View more

Kirk, I dug into this a little deeper. It looks like, in some cases, particular symbolsets have a "000000 - Unspecified" symbol entity as the default. The Atmospheric symbols - symbolset 45 and 46 as examples. So the initial pick of the METOCPoints, Lines, Polys triggers a search for the default entity: "symbolentity 0". Now, I _think_ the GetDictionarySymbol used to return a default symbol for undefined entities?? - but it could just be a bug in the sample - anyway, when I select a "real" entity from the symbolentity drop down (i.e. something other than 000000 - eg 110100), I get the correct symbol retrieved and loaded. I think the best thing to do is simply wrap the GetDictionarySymbol call in a try/catch to prevent the null symbol being returned from blowing up the dockpane in those cases where an unspecified "000000" symbol is being requested. private Task<ImageSource> GenerateBitmapImageAsync(Dictionary<string, object> attributes) { return QueuedTask.Run(() => { try { CIMSymbol symbol = ArcGIS.Desktop.Mapping.SymbolFactory.Instance.GetDictionarySymbol( "mil2525d", attributes); var si = new SymbolStyleItem() { Symbol = symbol, PatchHeight = 64, PatchWidth = 64 }; return si.PreviewImage; } catch(NullReferenceException) { return null; } }); }   ...

Hi Kirk, looks like a bug in GetDictionarySymbol. I'll keep u posted. ... View more

I see. Thanks for that.   What I told Mody to do was run a console executable, not Pro. However, for that console executable to run, it will need Pro installed. The console executable will need two references - the ArcGIS.Core and ArcGIS.CoreHost dlls - hence the name "CoreHost". ... View more
