Treeview Subnode Name - Return Name

All,

I don't have any problems getting the name or text of a root level node.
But when I try to get the subnode text or name, it always fails or returns
empty depending on code.

How do I get a sub node name?

TIA

Private Sub treeView1_NodeMouseClick(ByVal sender As Object, ByVal e As
TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick

Dim newSelected As TreeNode = e.Node

MsgBox(newSelected.Name.ToString) 'Returns Root Node Level

MsgBox(newSelected.Nodes(0).Name.ToString) 'Crashes app

End Sub

Hi,

Your code doesn't take into account that the node selected may not have
child nodes. Change your code to

If newSelected.Nodes.Count > 0 Then
MsgBox(newSelected.Nodes(0).Name.ToString)
End If

Happy Coding!
