[CLOSED] Icon in TreeNode does not work when generating "the AJAX-Way"
Hello,
when I add Icons to nodes in markup or initiallly in code behind, it works fine.
But when I add nodes before the Click event or something else, then the Icons are not shown.
The tree uses the folder- and file-icons.
As example I took the PageTreeLoader example and added Icons (Building and BuildingAdd):
I guess not, because both deliver JSON-Strings back, right?

Martin
