The custom application, using TrueDBGrid that the ComponentOne support department provided me works like a charm! The behavior is *exactly* what we need, and exactly what I was unable to create on my own. Our task now is to incorporate this code model into our production application currently in development, which I am confident we can do very easily. Needless to say, ComponentOne has saved us from a huge rewrite, and that is a big relief. Thank you, ComponentOne!
