I gave up on Delphi\'s DBGrid nearly a decade ago because it is simply no good. Since then, I have used Virtual TreeView which offers a lot of value but it has a few issues. Lik
Oooppppsss!
It's already added. Excuse-me.
You can see this, from Scalabium.
It's free and Sources included.
See the images at link.

I have had good luck with NextGrid.
It is extremely fast and Boki (the developer) gives very good support.

If we'd been voting I'd say TSMDBGrid. İt is almost perfect. Just a few days ago I checked its source code to see how it uses the filter edit (to exploit it, of course).
It is free too.
