Er .. that rather suggests that you're using the same databinding for all the boxes. Which in turn suggests that you have even less of a handle on this business than you suggested (no offence). Having said that this is kinda what you get for design time binding rather than learning the nuts and bolts of database manipulation. It looks like the easy option but it confuses the heck out of me!!

In this circumstance I'm not sure that I would be using bindings at all. You're not actually using the datarows as such, merely random(ish) cell values, so it really doesn't make a lot of sense to be tying yourself to the rigidity of the datatable.
