Rather than create another post can you tell me how you have the list view in DDT set so it does not wrap.

I am trying to recreate it within a data import wizard but once I add enough records to hit hit the bottom of the control it wraps back to the top instead of continuing down and scolling. I just cannot seem to find what switch to flip

This is the list view I mean.

myList.EnsureVisible(myList.Items.Count - 1)

That forces it to scroll to the bottom item in the list.
