>What DBGrid components is everybody (anybody?) using in their
production systems?
We commonly use InfoPower's TwwDBGrid, which has several rather
essential advantages over the Delphi TDBGrid but is far from perfect.
We've hacked around with the source to make another dbgrid of our own
which we use for specific purposes (it's not worth getting into here
because, while it does a lot, it relies on certain metadata tables for
information - it's not a standalone component).

I haven't yet seen another DBGrid that I'd rather I use. That doesn't
mean they're not out there. But maybe a data-aware TreeView?
>What GUI design have you used in place of DBGrids when they are not
efficient?
Generally we don't enable editing directly in our grids. We have the
data in grid format for selection and selection of columns for
exporting, copying to spreadsheets etc., and for displaying in an ad-hoc
report, and an associated screen which shows expanded details of the row
you're on at the moment. You do all your add, update, deletes, from the
associated screen (ideally it docks and undocks from the one with the
grid on it - will get around to that sometime). For bulk addition of
rows we have an autoinsert toggle.
One of the most annoying tasks we worked on was placing data in a
TreeView that should have really been data-aware. Instead we had
endless synchronisation problems with it (I didn't write it :P). I've
heard that there's a data-aware TreeView out now - that might be
preferrable to ever using a Grid at all. We've been too caught up in
other stuff to get around to evaluating it.
