All seems to work as expected apart from when editing values in the grid (the "child" records) the form's tool strip does not go into "edit mode". How can I get the MFTS to react to the child records in the grid / BO?

Also, for clarification: assuming I can get this working, what would the Undo button do to the child records? Would it undo all changes if I had changed multiple child record values in the grid or just the last row changed? I'm hoping the former...

Thanks in advance
