Drag multiple items from WPF listview

Question

I have a listview that displays files from a directory.
The user can drag each item in the listview to a folder/ the desktop and the associated file is copied there.

Answer 1

I'd like to point out an small error in the code

    Math.Abs(diff.X) > SystemParameters.MinimumHorizontalDragDistance &&
    Math.Abs(diff.Y) > SystemParameters.MinimumVerticalDragDistance)

should be

    Math.Abs(diff.X) > SystemParameters.MinimumHorizontalDragDistance ||
    Math.Abs(diff.Y) > SystemParameters.MinimumVerticalDragDistance)

Otherwise a straight Horizontal or Vertical will do nothing. Chances of that happening are small, but still..
