Add node under a spacific node, VB.net treeview

Hi I want to be able to add a node, under a spacific node. may be by path or index?

I have a table in a typed dataset in a win app, and need to loop through each row. I have an ID field and a ParentID field. I want it to be able to have infanate child nodes. So the only way I can see of doing this is when adding a node look to see if there are child nodes then add them. |Just not sure how to go about doing this.

This is what I have so far:

For i = 0 To Me.DataSet.sections.Rows.Count - 1
If Me.ActinicDataSet.Catalog_section.Rows(i).Item("ParentID") = 0 Then
Me.TreeView1.Nodes.Add(Me.DataSet.sections.Rows(i).Item("SectionText"))
'Need to add child nodes here.
End If
Next

The Add-function returns the created node as a result. You can then use that node as a parent to set the subsequent nodes.
Dim childNode As TreeNode = New TreeNode("Text for new childnode")
TreeNode node = Me.TreeView1.Nodes.Add(Me.DataSet.sections.Rows(i).Item("SectionText"))
node.Add( childNode )
