When I have a need to design a grid that goes into a form for editing, I use the cListObjEdit object and the cListobjEditForm class for the editing. I put the foreign key information in the form's PreSaveHook method like you show above but I also use the IN clause to make sure the correct table is being used. This works just great and it seems to use the form and class intended by the framework. The cListObjEditForm is a modal form and is generic enough to design it the way you need for most situations.

Hope this helps.
