VB.NET TreeView move to next node

adh
How do you move by program to the next node of a treeview (NextButton)?
Thanks

Hi

1. We can use the SelectedNode to get the current selected node
2. We use the NextNode Property to retrieve the next node
3. We set the NextNode to the SelectedNode, so that the "NextNode" will be
the current selected node.
e.,g.
Me.TreeView1.Se lectedNode = Me.TreeView1.Se lectedNode.Next Node

Thanks for the prompt reply.
My Nodes are sub nodes of Node(0) so
.Nodes(0).NextN ode
Did not work for me (it jumps to Node(1) not to the next sub node)
2)
.NextNode does not check the end of nodes. so what I'm using is:
With stvView.trvView s
If .Nodes(0).LastN ode.Index = .SelectedNode.I ndex Then
.SelectedNode = .Nodes(0).Nodes (0)
Else
.SelectedNode = .Nodes(0).Nodes (.SelectedNode. Index + 1)
End If
End With

????

Thanks, adh

Sure that will work, but you will screw up when you get to the end of a
branch and want to come back down the other side (if you see what I mean).

A proper traversal of a tree, in order, requires a stack (or recursion).
Your code below will traverse from the current position to the nearest leaf.

Hi

I agree with Robin's suggestion.
If you wants to traverse a tree strcture of treenodes, you need to use
recursion or stack.
