I need a little help with something.

I have an IB_Grid with multiple columns that can be ordered on. I am
changing the ordering column external to the grid with a radio box
control(don't ask why <g>). The ordering column is easy to change, but I am
having a little trouble moving the visual order of the columns in the grid.
I change the FieldIndex order but that does not seem to update to the
IB_Grid. Is there a procedure I need to call to get the changes made to
FieldIndex to reflect in the IB_Grid?

Thanks,
Paul
