Extended TreeNode

[Hakan Ugur]

Hi All,
I got a treeview object. I extended its TreeNodes to ExTreeNode and then
added ExTreeNode to Treeview control and binded to screen. And then, when I
try to read treeview it returns TreeNode instead of ExTreeNode. When I try
to cast to ExTreeNode, it throws Invalid Cast Exception.

Have you got any idea?

Thanks.

did you override CreateNode in your custom treeview to create an ExTreeNode?
