I have a programmer that has an AdvancedTreeView class that is derived from TreeView and AdvancedTreeNode drived from TreeNode.

There was some additiona formatting on the node added. Long story short the control initially populates the primary level 0 just fine.

We'll click on the node to expand it and we'll get in the tree first a message saying "Object could not be set to the reference"..... then after that it's "Inputstring is not in the correct format.

AJAX is using the "CreateNode method which he overroad just to return a new AdvancedTreeNode (as a TreeNode)....

I can't find where the exception is being thrown and I'm not ASP expert. Any help you have would be great on how to solve this....
