I have a ListView in IconMode which supports drag & drop for reordering the items by using the ListViewDragDropService:
dim myDDService as new ListViewDragDropService = ListView.ListViewElement.DragDropService
It works fine. Now I try the same with a databound ListView but I doesn't react on dragging. When I remove the databinding and fill the listview manually with the items, drag and drop works. 

Hello Elke,

Thank you for writing.

The built in drag and drop feature of RadListView does not support drag and drop in bound mode. We already have related feature request in our Public Issue Tracking System, so you can subscribe to it and track its status here: http://www.telerik.com/support/pits.aspx#/public/winforms/9787

I hope this information helps.

Kind regards,
Anton
