Just a thought....

Place the items in a StringList and set the sorted property to True.
That will keep them sorted alphabetically.

There are database components in D4, but I haven't had the need to use

Maybe even use a tree view component.

There would be lots of ways to sort and store and view the data
depending on your needs.
