Populate a listbox from range

Hi,
I'm trying to Populate a listbox from range (that's easy)

UserForm1.ListBoxResults.List = DB.ListObjects(1).DataBodyRange
'DB is WS

And getting errors if auto-filtering the DataBodyRange by a simple criteria1.
Any idea why?

UserForm1.ListBoxResults.List = _
DB.ListObjects(1).DataBodyRange.AutoFilter(field:=1, Criteria1:=SortString)
'SortString is just a word
