TreeNode.Remove(Boolean notify) exception

[Boni]

Dear all,
I have a tree node inherited from TreeNode class. Sometimes when I call
Nodes.Clear() I get following exception.
I use .NET 2.0.50727.
Seems to be MS bug?
Any ideas?
Thanks
Boni

It is telling you that "Nodes" is set to nothing when you are calling Clear.

Try this:

if Nodes isnot nothing Nodes.Clear
