As an update, replacing Guid with String in the database and code worked. I got everything to work except the "parser stack overflow" error. The application is much snappier than when running with a SQL Server LocalDB database.
Is there any way to solve this parser error? One work-around could be to first load the main data of my grid and afterwards load the extra columns asynchronously... which would allow me to cache the calculated data and improve performance. But that would require considerable coding. Any better solution? Thanks, Etienne
