I have an UltraCombo for which I defined the schema manually at design time. I'm using SetDataBinding method to bind a custom collection and to hide the new columns.

When I use SetInitialValue to defer the dropdown load, all the columns are showing up. Any ideas on how I can make the grid show only the columns defined at design time?

cboPrimarySupplier.SetInitialValue(0, "...");

cboPrimarySupplier.SetDataBinding(itmColl, null, true, true);

Thanks,

Ramesh
