XamDataChartView Thread Access Error

Gary Wrinn posted over 9 years ago

We have a main WinForms application that hosts WPF forms - these forms are started with their own dispatcher thread using this code:

            if (Util.MultiThread)
            {
                // http://reedcopsey.com/2011/11/28/launching-a-wpf-window-in-a-separate-thread-part-1/
                // http://eprystupa.wordpress.com/2008/07/28/running-wpf-application-with-multiple-ui-threads/
                Thread thread = new Thread(() =>
                {
                    try
                    {
                        // Create the application object and load WPF resources
                        Program.EnsureApplicationResources();
                        System.Windows.Window w = wpfForm();
                        System.Windows.Forms.Integration.ElementHost.EnableModelessKeyboardInterop(w);
                        w.Show();
 
                        // When the main form OR window closes, shut down the dispatcher
                        w.Closed += (s, ea) => w.Dispatcher.InvokeShutdown();
                        CommandInvoker.MainFormRef.FormClosing += (s, ea) => w.Dispatcher.InvokeShutdown();
 
                        System.Windows.Threading.Dispatcher.Run();
                    }
                    catch (Exception ex)
                    {
                        ShowException(ex);
                    }
                });
 
                thread.SetApartmentState(ApartmentState.STA);
                thread.Start();
            }

One of our WPF forms frequently gets the error shown below and crashes, after which, the WPF form can no longer be opened and the application has to be restarted to restore this. We cannot produce this on demand, but it can happen several times a day. We have tried using v15.1.20151.2055, but the issue still occurs. None of our actual code is being accessed based on the stack trace, but Infragistics.Controls.Charts.XamDataChartView.OnTemplateProvided() seems to start the issues. Can some one explain what this class/method chain is doing that might cause this issue or something else that might be causing this.

Actual stack trace:

System.InvalidOperationException: The calling thread cannot access this object because a different thread owns it.

Hello Gary,

Thank you for your post!

I have been investigating this issue, but I haven't been able to reproduce it as of yet. However, the code that you have included does raise a couple of questions on my end, since I am not entirely sure what your wpfForm() and EnsureApplicationResources() methods are doing. I imagine wpfForm() is simply returning the Window to be shown, but I could be mistaken.

I have attached the sample project that I have been using to try to reproduce this issue you are seeing. Could you please take a look at it and modify it so that it includes a more accurate representation of the EnsureApplicationResources and wpfWindow() methods so that I can see what you are seeing on my end?

Please let me know if you have any other questions or concerns on this matter.

Sincerely,
Andrew

Thanks, I have attached a quickly updated file set - this includes the EnureApplicationResources() method, but some DLL inclusions are probably needed for this to compile) - essentially, this loads XAML needed for customizing a XamGrid and that requires a stock Infragistics generic XML file.

We are not able to produce this on demand, so any insight you can give to what these methods are doing might help:
