OK, it turns out, that this solution won’t show the empty Folders (when there are no files in it).
If I write by hand into the TreeView dataset just the Path then ‘Null 1’ is shown…
But our customer wants to show these empty folders also…
Does anyone have an idea, how to do that?
EDIT: That’s what I/we need: Tree View Folder without a Node object? - #2 by Travis.Cox
