Edit a treeview-node and then sort the treeview

Hi,

I have found a question and solution on the internet:

Question:
After a node's label is edited in the tree I try to resort the nodes to place the updated item in the right position. I do this by calling .Sort in AfterLabelEdit event handler which causes an infinite loop.
How can I resort the nodes in a treeview after a label has been changed?

Answer:

Use BeginInvoke:

delegate void sort();

    private void treeView1_AfterLabelEdit(object sender, NodeLabelEditEventArgs e)
    {
        treeView1.BeginInvoke(new sort(treeView1.Sort));
    }

I have the same problem but I don't know how to implement it in my
code. I have put the code for editing a treeview node in the code-section.

Who can help me?

Peter
