I don't think that's the right approach. The dataprovider is meant to provide the data, and not really know how its displayed. Sure the sortabledataprovider is kind of on the fance, but I think sorting is more of a data artifact rather then a presentation one. I think the breakage into columns should be handled by the display component. The rows container can pull the iterator out and just pass that to the columns container...a orderedrepeatingview inside a dataview? Just thinking out loud... -Igor
