aspdotnet_website_programming thread: Is it possible to maintain treeview state?

I have searched the Internet for this very simple question to no avail.
I have a treeview on a aspx page, and the node's NavigateURL is pointing
to anther web page; after viewing that page I return to the aspx page with
the treeview. The problem is that the treeview returned to its original
un-expanded state. Is it possible to have the treeview stay at the last
state?
(setting the AutoPostBack and EnableViewState to true has no effect)
Any help is highly appreciated.

This is a longshot - You mentioned setting the autopostback value - but did
you ever check it in your pageload event?
everytime the page comes to the server the pageload event runs again, so is
your form just being recreated?
hope it helps!

As a common programming practice I did check IsPostBack, but click a link
doesn't fire the postback at all. Anyway, I have to use a IFrame and put
Javascript in the NavigateURL to make the treeview stay what it was and
load the page in the IFrame; It works pretty well.
I can provide code snippet if anybody interested in implementing this
navigation scheme.
