Now, like in explorer, when the item is clicked once, you can edit its caption By using the AfterLabelEdit event, you can check that the new caption is valid, and that it is not empty: Private Sub TreeView1_AfterLabelEdit(Cancel As Integer, NewString As String)     If NewString = Empty Then         '// new string is empty         Msgbox "Please enter a new name"         '// cancel edit         Cancel = -1     Else         '// string ok     End If End Sub There is also an BeforeLabelEdit event that occurs before the item is edited. You can use this to prevent the root item being edited, for example: Private Sub TreeView1_BeforeLabelEdit(Cancel As Integer)     If TreeView1.SelectedItem.Key = "root" Then         '// item is root item         Msgbox "You cannot edit the root items name"         '// cancel edit         Cancel = -1     End If End Sub « Using Images | Expanding Items » James first started writing tutorials on Visual Basic in 1999 whilst starting this website (then known as VB Web). Since then, the site has grown rapidly, and James has written numerous tutorials, articles and reviews on VB, PHP, ASP and C#. In October 2003, James formed the company Developer Fusion Ltd, which owns this website, and also offers various development services.
