Hi Jay,
As far as the developers tell me, then the DataGridView’s EditMode feature contains several problematic issues in matter of client - server design and that is the reason why this issue was scheduled to version 7.0. This means that it is not feasible to reschedule that particular issue as a whole to 6.4.
What we are willing to do however, is taking a closer look as some specific issues with the DataGridView editing that you are having problems with and if they prove to be more easy to solve than the whole issue, then it may be possible to create a new issue on that and schedule to 6.4.
Please comment on the specifics of your problems here, preferably with a sample application and we'll evaluate your request.
Hope this helps,
Palli
