RowReorder anyway to prevent row to be moved to above the first header?

jens.olsson

I have a DataTable with some Items that I want to use as top level items. The idea is then to be able to move all the "subitems" between the top level items. It works fine except that I am able to move the items to the first row which in fact moves the item outside of the hierarchy. Please see the example and I believe it will be easy to understand my problem.
