I Have this popup error when I click or expand a node of the radtreeview "Specified cast is not valid.s[]_$$_". I don't know why. I don't know how to debug it.
The popup appears when I execute this javascript function : node.expand();
This error appears all the time in Explorer, and sometimes in Firefox.
Thanks in advance,
