This is almost certainly the problem, then. If you make changes to the data on another thread and the grid tries to access that data on the UI Thread for any reason, this can cause all sorts of problems.
Hello,
I have the latest hotfix(7.3.1043) but the same error still occurs. Sometime: "Object references not set", sometime: "Index was outbound of array"...I use UltraWinGrid to load data in multithread by BackgroundWorker. Here is mesage error:
You can get hot fixes from the Infragistics web site.
You can try setting the Visual Studio IDE to break on all run-time exceptions to see if you can catch the exception, but with something like this, it may not be possible.
can send the latest hotfix for me? or any idea how i trace the exception point and throw the errors above.
This kind of error ususally means something raised an exception during the Paint event of the grid. These are pretty hard to debug.
I would suggest the following:
1) Make sure you have the latest Hot Fix.
2) Errors like this are often caused by multi-threading. If your application is using multiple threads, then you may need to check InvokeRequired and make sure you are not causing changes that go across threads without the proper marshalling.
