IE WebControls Treeview: manual postback?

Hi,

I have an ASP.NET application that needs to have a treeview. I've chosen the Microsoft Treeview because it is free of charge. I'm creating the following structure in my treeview:

- Access Points
  - Monthly
    . Code 01
    . Code 02
  - Periodically
    . Code 03
    . Code 04

I only want the treeview to postback at the lowest levels (when a user clicks Code 01, Code 02, Code 03 or Code 04). For the other nodes I don't want to have a postback because this causes overhead.

How can I best do this

Thanks in advance !

Greetz,
