Hi Marco,

I dont really understand the question.

I do know that there can be issues using IB_CtrlGrid - where controls
on the grid need to be designed specifically to be replicatable. The
results of incorrectly designed controls of CtrlGrid can be very
strange and inconsistent.

As for the master-detail and closed dataset aspects, please explain
what you mean in more detail.
