Bruce,

Why not just RemoveObject() the columns you don't want to show?

You can set the Column.Resizeable = .f. to prevent it being resized. Set Moveable = .f. to prevent it from being moved and prevent the mouse arrow from changing to a down pointing arrow. But you will have a 1 pixel wide representation of that column that you won't be able to get rid of. You might move the 0 width columns to the right or left sides of the grid.
