Export of GridControl from a separate UI thread throws "The calling thread cannot access this object because a different thread owns it" exception

created 9 years ago (modified 9 years ago)

Hi,

Export works correctly for the first instance of the grid control but fails for the second one with "The calling thread cannot access this object because a different thread owns it." exception.

Steps to reproduce.

  1. Run the application
  2. Click "Open new GridControl" button. New window will open.
  3. Click "Export" button at the top of the component. Export works correctly.
  4. Click "Open new GridControl" button. New window #2 will open.
  5. Click "Export" button at the top of the component. Export fails.

If I remove "ShowTotalSummary="True"" from the TableView definition in the .xaml file then everything works correctly. I'm sure it uses some kind of shared static resource that is causing this issue.

This issue is a "showstopper" as we can't release our product because of this.

Thank you,

Eugene

        When do you expect 1.11 to be released? We're currently on 1.8.

          1.10 is not available for download… The highest version is 1.9 (released on December 7th). Please advice.

            Hi,

            The current 15.1 version is 15.1.9. And, you do not need to wait for v15.1.10 to resolve the issue - just install the hotfix from this thread. You can request it as described in the How to request a hotfix article.

            Regards,
            Alex
