Question

I have a treeview with nodes like this: ‘Foo (1234)’, and want to allow the user to rename the nodes, but only the Foo part, without (1234). I first tried to change the node text in BeforeLabelEdit like this:

private void treeView1_BeforeLabelEdit(object sender, NodeLabelEditEventArgs e) {     e.Node.Text = 'Foo'; } 

But when I click the node to edit it, ‘Foo (1234)’ appears in the textbox.

Okay, then let’s try something else.

I set treeView1.LabelEdit to false, and then do the following:

private void treeView1_MouseClick(object sender, MouseEventArgs e) {     if (e.Button == MouseButtons.Left)     {         if (treeView1.SelectedNode == treeView1.GetNodeAt(e.Location))         {             treeView1.SelectedNode.Text = 'Foo';             treeView1.LabelEdit = true;             treeView1.SelectedNode.BeginEdit();         }     } } 

And then in AfterLabelEdit, I set LabelEdit back to false.

And guess what? This doesn’t work either. It changes the node text to ‘Foo’ but the edit textbox does not appear.

Any ideas? Thanks

Finally I have found a solution to this on CodeProject. Among the comments at the bottom, you will also find a portable solution.
