Hi,
I created a small sample project based on your code. My grid actually has 15 columns (with a variety of data type) and 200,000 rows. And I am able to run the application and export the grid to Excel successful with no Exceptions.
Please try my sample and see if the exception occurs with my sample.
If you get the same exception with my sample (and I don't) then that would indicate this is an issue with the versions of the Infragistics or other assemblies on your machine. I am testing with our latest internal build so if it works fine for me and not you, I recommend that you try getting the latest service release and see if that fixes the problem.
If you do not get the exception with my sample, then it means something else in your application is causing this. Perhaps you are using a particular data type of some feature of the grid that I am not. So we would need to narrow that down.
Also, if you can, I recommend trying this with fewer rows, just as a test to see if the number of rows is relevant to the issue. It takes a long time to export so many rows, and testing and debugging will go a lot faster if you can reduce the time it takes to test.
Finally, I'd be interested to know if the location to which you are saving matters. The Temp folder might be protected by Windows, so you might try saving somewhere else, like to a non-system folder and see if that makes a difference.
Hi Mike
We are still busy tracing the error, in the meantime could you please supply a link to the following Service Release downloads:
Infragistics_WindowsForms_16.1_ServiceRelease_2033.zip and
Infragistics_WPF_16.1_ServiceRelease_2056.zip
