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

Try this:

if Nodes isnot nothing Nodes.Clear

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

System.NullReferenceException: Object reference not set to an instance of an
object.
at System.Windows.Forms.TreeNode.Remove(Boolean notify)
at System.Windows.Forms.TreeNode.Clear()
at System.Windows.Forms.TreeNodeCollection.Clear()
