A really goofy way to do this is to bind on the descriptive field (resolves what's displayed) and use a view and do a REPLACE on the key on LostFocus. This is what I've been forced to do in the past.

>>>Sparse shows the boundcolumn, which is the surrogate key. I don't want to display the surrogate key.

I use the second view and set a relation to it to avoid having to requery every time the user changes the supervisor. I only requery after the user choses to do an update. The user can change many records before update.
