Before calling your resize, call grid.CurrentCell.MoveTo(-1, -1) to see if that avoids the problem.

I do not have any other suggestions than those Stefan posted in http://www.syncfusion.com/Support/Forums/message.aspx?MessageID=35322. The problem is that the inplace RichText cell resizing is using a hack to try to do the optimal sizing. There may be a better way to do the sizing in richtext (or there may not be), but you would have to use interop and would direct with the Win32 richtext control attack this problem. The .NET wrapper on the Win32 RTB does not exposed any optimal sizing facility that I know of. The hack that the InPlace Richetext cell uses was one way around this problem, and seems to work ok for small amounts of text. If it is too slow, and you cannot find a interop solution using the Win32 API, then either restricting the sizing to the visible cells, or trying to size the cells on emand immedaitely before they are displayed would be the only approaches i know to reduce the effect of this problem.
