That sounds like it would work, but that would mean that the
changes will not get posted until the user exits the screen,
or I will need to setup a timer to fire the commit in a timely
manor.

We are editing data, the field is non-nullable in the db how do
I make the program IBOBjects checkbox in the grid realize that
it is non-nullable and stop allowing it to change to null?
