one parent table T1 and two child tables Ta, and Tb.

So there are two relations in this dataset:

Relation 1: T1 => Ta

Relation 2: T1 => Tb

If I set

myUltraGrid.DataSource = myDs;

then it shows:

Band 0: T1

Band 1: Ta

Band 2: Tb

so well all correct!

But my question is:

how can I change the band index, so that I can get the following result:

Band 0: T1

Band 1: Tb

Band 2: Ta

Many thanks in advance!

P.S. It works, if I add the Relation 2 (T1 => Tb) at first into dataset, then add the Relation 1 (T1 => Ta)

but can we use any method, such like: myUltraGrid.DisplayLayout.Band[1].VisibleIndex = 0?
