>A view can help with displaying (and editing) information from another table, but I do not think it addresses the problem of presenting a dropdown style list for foreign key entry. I think I'll need to create my own control that uses a grid for the drop down list since combo boxes are too slow for large files.

well, using a grid is a good solution on many occasions
but I am not sure u need it here u just have to update the combobox whenever u change a record (e.g. REQUERY the view) so that it will display the new related info
