Treview - Node (Parent - Root ?)

Hi,
when using a treeview how can you tell if a specific if a specific node is a PARENT a CHILD or the ROOT NODE

:) Thanks :)

If the node is the root node the parent property will be nothing.

If the node is a parent node then the parent property will be not be nothing and the child property will not be nothing.

If the node is a child node then the child property will be nothing

Code:

---

Private Sub TreeView1_NodeClick(ByVal Node As MSComctlLib.Node)

   
    If Node.Parent Is Nothing Then
      MsgBox "ROOT"
    ElseIf (Not Node.Parent Is Nothing) And (Not Node.Child Is Nothing) Then
      MsgBox "PARENT"
    ElseIf (Node.Child Is Nothing) Then
      MsgBox "CHILD"
    End If

End Sub

---

Hope this helps.

It seems i can't edit my posts so i will have to post again.

Rather than testing the child property against nothing you can test the children property. This property holds the number of children a node has. If the value is 0 then it is obviously a child node.

Code:

---

Private Sub TreeView1_NodeClick(ByVal Node As MSComctlLib.Node)

   
    If Node.Parent Is Nothing Then
      MsgBox "ROOT"
    ElseIf (Not Node.Parent Is Nothing) And (Node.Children > 0) Then
      MsgBox "PARENT"
    ElseIf (Node.Children = 0) Then
      MsgBox "CHILD"
    End If

End Sub

:) Thanks Alot :)
