This list does not accept attachments.

But probably does not matter. What you describe in terms of
function is already available. It is only the details of user
interaction that need to be clarified.

If you need F2 to work exactly as Alan is looking for then he
has already described his work around on this thread. (And we
can discuss "fixing the problem" with Jason for a future
release.)

If you need help to set up your TIB_Grid with TIB_LookupCombo
for each column then I suggest starting a new thread. I think
the Contact sample has a lookup on a grid as an example.
