Method Two:

method Two: Use of MouseClick and AfterLabelEdit, Treeview1.labeledit=trueThis sentence is indispensable: PublicForm1 () {InitializeComponent ();  This. load+=NewEventHandler (Form1_Load); Treeview1.mouseclick+=NewMouseEventHandler (Treeview1_mouseclick); Treeview1.afterlabeledit+=NewNodelabelediteventhandler (treeview1_afterlabeledit);} Private voidForm1_Load (Objectsender, EventArgs e) {     for(inti =0; I <Ten; i++) {TREEVIEW1.NODES.ADD ("TV"+i.tostring ()); Treeview1.nodes[i].
