Hi,
You can create custom image files for non-expandable node and expandable node, and then place them in a directory in your Web site, and then set the following properties on your TreeView control to reference the images:
-
CollapseImageUrl
-
ExpandImageUrl
-
NoExpandImageUrl
For more information, see Customizing the Look and Feel of the TreeView Web Server Control ( http://msdn.microsoft.com/en-us/library/ms178262.aspx).
I look forward to receiving your test results.
