Tree-like Datastructure (for use with VirtualTreeview)

Question

I have come to the point where I need to stop storing my data in a VCL component, and have an \"underlying datastructure\", as Mr. Rob Kennedy suggested.

If I understand correctly, you need a datastructure for your tree. Each individual node requires a record to hold its data. But the underlying heirarchy can be managed in a few different ways. Im guessing this is all to be managed in some sort of database - This has already been talked about on this site, so i will point you to:
