Hi,
I get this exception when I try to expand a node on the 2nd level on a 
TreeView webcontrol.
The TreeView webcontrol works fine when I expand the first level, but fails 
when I try to expand it on the 2nd level.
The nodes in the treeview only have the text property set, and the info is 
gained from cached data, which on it's turn is extracted from a database.
There are only 3 levels in my treeview. My page exists out of a few tabs & 
pageviews. On the last tab, there is a self made webcontrol that contains 
the TreeView control.
My webcontrol is supposed to display the structure of my webpage(tabs, 
webcontrols like textboxes, labels, etc and the tables they are contained 
in.
Anyone know what could be the cause of this and more importantly, how do I 
fix it?

Here is the explanation I get when the exception is being thrown.

Kind regards,

Forgot to add that the webcontrols are in a different VC# project than the 
webpage, but still in same solution.
Got a webproject that contains all my webpages and a control project that 
contains all my webcontrols.
