Removing SubNodes - HELP!

[LeeSalter]

I have this code in the AfterCollapse event of my TreeView control:-

        Dim subNode As TreeNode

        For Each subNode In e.Node.Nodes
            MessageBox.Show("removing " & subNode.Text)
            subNode.Remove()
        Next

        e.Node.Nodes.Add("")

I want the control to remove all sub-nodes after it has collapsed and then add a blank dummy one at the end.

It falls over about half-way through with a "Object reference not set to an instance of an object" error.

It appears to be trying to remove the same sub-node twice!
Any ideas???

Did it this way instead:-

        Dim i As Integer
        For i = 1 To e.Node.GetNodeCount(False)
            e.Node.Nodes.RemoveAt(0)
        Next

        e.Node.Nodes.Add("")

Cheers.
