trouble with treeview and parent/child nodes -

Code:

---

+root
  +parent1
      -child1
      -child2
  +parent2
  +parent3
        -child1

---

using dotNet v2003

with this example above - how can I determine that parent2 is really a 'parent'?

also, say i click on 'parent3' node, how can I determine that this is a parent node with children?

VB Code:

Private Sub TreeView1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles TreeView1.Click
        Try
            Debug.Print(TreeView1.SelectedNode.Parent.Text)
        Catch
 
        End Try
    End Sub

All I could get..Im sure someone could do something better..

You can use GetNodeCount method to know if a node has children, and how many.
GetNodeCount receives a boolean parameter, if True, it returns how many children that node has in all Treeview levels (recursive), if False, it returns how many children it has just in the next level (its direct children).

VB Code:

Dim NodeCount As Integer = TreeView1.SelectedNode.GetNodeCount(True) 'True = Recursive search
        If NodeCount = 0 Then
            MsgBox("No children!")
        Else
            MsgBox("This node has " & NodeCount.ToString() & " children")
        End If
