Hi,

The way to create a TreeView is to ensure that you create a reference to the Parent Node that you want to add children to.

To demonstrate, have a look at this quick example:-

Public Class Form1
 
  Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
    'Declare the Parent node of the Treeview
    Dim ParentNode As New TreeNode("ParentNode")
 
    'Add the Parent Node to the Treeview
    TreeView1.Nodes.Add(ParentNode)
 
    'Now use the Parent Node Object to add a defined Child Node
    Dim ChildNode As TreeNode = ParentNode.Nodes.Add("ChildNode")
 
    'Now use the ChildNode Object (which is now another Parent to its own children) to add Another defined Child Node object
    Dim AnotherChildNode As TreeNode = ChildNode.Nodes.Add("AnotherChildNode")
  End Sub
End Class

Hope that helps.

Cheers,

Ian
