Home Forums WinForms controls Xceed Grid for WinForms Cross-thread operation not valid Reply To: Cross-thread operation not valid

I tried commenting out all other threads in my program and re-run it. I still got the error. It seems to me that the error would be thrown if I open a form (which contains a grid and some buttons) and close the form (by clicking a button on the form) and doing this repeatedly for several times. It is really strange that a cross-thread operation could happen. From the stack trace, it shows something about disposing a grid element. I wonder what the stack trace tells about. Also, any help regarding this cross-thread operation error would be much appreciated. I really have no clue how to fix/debug it further. Thanks.

System.InvalidOperationException was unhandled

  Message=”Cross-thread operation not valid: Control ” accessed from a thread other than the thread it was created on.”
