Take a look at this site: http://www.syncfusion.com/FAQ/WinForms/ This guy has a lot of documentation on Windows forms including Grids and TableStyles.

I also thought it was redundant having to assign the table in the grid and in the table style. Later on I realized why you need to do this, but it's been so long that I have forgotten already. Hope that site that I mentioned gives you the answer.

>>I think you are missing the MappingName in the TableStyle. You need to indicate the TableStyle the "table" that is bound to.
