I will have to look at this in the htel room tonight. Just so you know, we are creating a full featured Infragistics wrapper. It will include native grid support, so don't worry
... it will be "fully supported' if you are having some issues now. I will look into this and see if I can reproduce the problem and give you a solution. Normally we have an extremely quick turnaround on posts. But the entire team is scattered all over the U.S. this week which generally never happens. In fact, some of us are at Microsoft at the VSIP summit.
