Drad n drop on list view issue

I should like a list view only with images (without text).
But...
DragNDrop Works:
(dcl-ListView-FillList DragNDrop/Form1/ListView1 '(("List 1a" 0) ("List 2a" 1) ("List 3a" 2)))
DragNDrop Don't work:
(dcl-ListView-FillList softline/Form1/ListView1 '(("" 0) ("" 1) ("" 2)))


Any work around ?

Thanks !

Does it help to enable {2}?

No it doesnt help.
I replaced "" strings by " " strings: It works, but the empty string is highlighted when the image is selected ...
