hello-

i populuate my treeview from a db on form_load.

i want to give my users to expand all parent/child/sibling branches or collapse all.

by default, when the form loads, i coded a few fixed branches to be expanded, but the child branches are all collapsed by default.

an example would be great.

To expand all use the following

Dim a
For a = 1 To TreeView1.Nodes.Count
   TreeView1.Nodes(a).EnsureVisible
Next a

To collapse all use this

Dim a

For a = 1 To TreeView1.Nodes.Count
   
   If TreeView1.Nodes(a).Expanded Then
          TreeView1.Nodes(a).Expanded = False
       End If
   
Next a

If you don't want it to collapse all the way back to the parent but you want theparent an it's children showing use

For a = 2 To TreeView1.Nodes.Count
