I don't know and can't think of any good reason 9or even a bad reason for that matter (s)) for that however it seems that MS does while you can without much trouble (if you know well enough how .VCXs are constructed..) create a column entry in a VCX - and use it (I can send you an example if you like) the classbrowser will not let you edit the class (the problem btw is not with the class browser but with the class editor that pops "this class cannot be edited visually") btw, note that when you create a grid - no column objects are created in the VCX - all the columns info is stored in the record reserved for the grid...
