TreeView Nodes - Can they be externally instanciated?

[Judd]

Hola peeps,

Is it possible to instanciate a treeview nodes collection externally from the actual control, build up the tree and then use something like:

Set TreeView1.Nodes = MyNodes

to display it?

I can't think of any way other than to use a second 'invisible' treeview control?

Anyone?

(I guess I want to be able to add whoel nodes to a treeview without having to create all the sub-nodes...I want to store my nodes so I don't have to do a complete refresh of my tree-view every time something changes...)

I thought this might solve the above problem, but apparently not.

I can't believe there is no way to add complete nodes to a tree....it seems like an obvious thing to want to do

Private Sub Form_Load()

    Dim tvw As Object
    Dim nde As Node
    Dim nde2 As Node
    
    Set tvw = CreateObject("MSComctlLib.TreeCtrl")
    
    With tvw
        Set nde = .Nodes.Add(, , "ROOT", "Root Node")
        Set nde = .Nodes.Add("ROOT", tvwChild, "CHILD1", "Child One")
        Set nde = .Nodes.Add("ROOT", tvwChild, "CHILD2", "Child Two")
    End With
    
    Set nde = tvw.Nodes("ROOT")
    
    Set nde2 = TreeView1.Nodes.Add(, , "R", "Tv1 Root")
    
    Set nde.Parent = TreeView1.Nodes("R")
    
End Sub

Can I copy a node from one treeview to another or not?

Where are the gurus and hyperactive members when you need them?

I think nobody likes TreeView except me...

There's no direct way to copy everything from TreeView to another with one line of code. You would have to manually loop through nodes collection in one TreeView and populate another. If you need help on coding, just let me know.

Thanks Serge..

I had figured that there wasn't a way around the problem (which, frankly, is just sh*t on the part of the MS originators!).

As I mentioned elsewhere (Persistance Is Futile) my preferred route is using an invisible Tree to store my nodes and transfer them as and when to the visible tree (so I don't have to load them every time....)

I'll be sure to give you a shout though, should I get stuck again..

Cheers,
