Yep, it can be done by converting to a string, but as you pointed out, it's non-trivial. I was hoping for an easy way or some property setting I'd missed.

Thanks for the help.

When it changes (ProgrammaticChange), initiate a method that re-displays the other TextBox that is a character field showing iif(X>0, "+" + str(X), str(X)). You get the idea.
