>A Checkbox can be centered if you create a Container class that contains the Checkbox and place that in the Grid's Column.

This worked great for me! Only thing, when pressing the down key while on the checkbox column (to go next record), it shifts right to the next column (or up key, shifts left). Why? How may I force it to go down (or up)? Checkbox not in container class worked just fine. Is it because the container class doesn't recognize it's being in a grid?
