Updatable Hierarchical Structure

[Vlad Chapranov]

I have a hierarchical data: Job can contain one or more Orders, each Order can have one or more Details and each Detail may have one or more Partials. I found the way to display this hierarchie (with MS Hierarchical Grid), but I need to add new records, delete, update. How can I do that? Data Form Wizard can create Master/Detail structure. But even with two levels I can't do anything with data in a grid.
Thank you
Vlad
