I have read on this forum a couple of "how to" implement the ComponentArt CategoryTreeView and it works.
My problem is that no mather how I try to modify the different parameters I cant get it to look like this "Bare Bones" version I want:
http://www.componentart.com/webui/demos ... Form1.aspx
In my installations of Able 7 (latest build) i allready have a image folder with all the images (App_themes/images/ComponentArt/TreeView/lines), I just don't now how to modify the parameters correct. Or do I need something else?
Anyone who can give me some tips how to modify this code to make it look like the example link above?
Best regards, Thomas
