An empty dataset is..well...empty. It contains no data. Therefore, there
are no data from which to read attributes. IBO does not create persistent
TField objects to which you can apply attributes. Once the TIB_Column
objects exist, they acquire the attributes you have defined for them and
the behaviour of the controls is directed by the data.

If it is an aesthetic problem for you, why don't you test your dataset's
IsEmpty property and paint the controls accordingly?

Are you writing applications that usually present empty datasets when the
datasets are opened? If so, it would be good coding economy to write your
own descendant controls that react to this condition in the way you prefer.
