I have a form with a subform. In the subform there is a datasheet where the
operator do edit, add, delete.

The sequence of the columns in the subform datasheet is set in design mode
by setting taborder. The operator can select a column and drag it with the
mouse to alter the sequence of the columns.

How can I prevent the user from dragging the columns and changing their
sequence?

Alternatively I could repair the sequence of columns every time the subform
is opened. How can I do this in vba?

Regards
