if i have a few nodes expanded if the page is refreshed they all collape.  How do you keep the nodes you have expanded open after a refresh or a page change?

Hi Ryan,

One suggestion is that to use the GetXML() method to get the current state of RadTreeView as XML string and save the XML string. When you decide to restore your Treeview call the LoadXmlString() method to populate the treeview from the previously stored XML String. Please refer the forum link which discusses similar scenario.
