TreeView Control Questions

[Guest]

I'll admit, it was late....but I could not find the answer to these two
questions.

How can determine if the node that a user clicked on:

1) is a parent (top level only)?
2) has children?

Thanks

Hi,

Private Sub trvNorthWind_AfterSelect(ByVal sender As Object, ByVal e As
System.Windows.Forms.TreeViewEventArgs) Handles trvNorthWind.AfterSelect

Dim n As TreeNode

n = e.Node

If n.Parent Is Nothing Then

Debug.WriteLine("Top Level")

End If

Debug.WriteLine(String.Format("Number of children {0}",
n.GetNodeCount(False)))



End Sub

EdB,

1) is a parent (top level only)?

If TreeView.TopNode Is TreeView.SelectedNode

2) has children?

If TreeView.SelectedNode.Nodes.Count > 0
