Should controls used as embedded editors in grid be hidden o

I figured I'd ask here before reporting as a possible bug.

I've got a UltraGrid that contains an UltraCombo as one of the column editors. I added the UltraCombo to the form and then, in the designer, I assigned the UltraCombo to the grid column's EditorComponent property.

The UltraCombo still show on the form at run time even though it's working and displaying in the grid column. In fact, it's even enabled in the form and when I navigate the combo's rows in the grid, the one in the form shows the same values.

Should the one in the form automatically be hidden?

Thanks,

Jim
