Thank you for writing.
According to the provided description, I am not sure how exactly you setup
the columns. However, if the Name
property of the column is specified, it is expected to use it in order to access the respective cell. I have prepared a sample project for your reference. Am I missing something? Could you please specify the exact steps how to reproduce the problem? Thus, we would be able to investigate the precise case and assist you further.
I hope this information helps. Should you have further questions I would be glad to help.
