Nick,
If your grid was "in" the container then it will behave the same as the other controls. But it sounds like your grid is "on" the container.
>I am using the container to prevent users from changing information on screen. Since I had different type editboxes,grids,combos,checkboxes (this one always look funny when enable .f.) etc... I decided to use container to prevent users from entering these objects and changing stuff. Could have used setall command to enable but this was easier.
