>I don't know how I ended up with a couple properties for a Grid in a VFP 9.0 form. I can't duplicate this for some reason in a VFP 6.0 form. Unfortunately, I have to do coding in both VFP 6.0 and 9.0. One property is called "lAboutToLeaveGrid" and the other is "nRecNo"; both are used to handle the row colors of the grid.

Those are not native properties but custom properties defined in the class your grid is inheriting from under VFP 9. It sounds like the grid classes you are using differ between your VFP 6 and VFP 9 implementations.
