Embedded windows control in browser reload into new web page

Question

Hi there, I've (finally) been able to embed a treeview inside a web page. Now the problem is I want all of the text in the nodes to be links to various web pages. First of all, how do I store a link inside a treenode? Should I use the Tag property? Second of all, is it possible for me to load a new web page into the window that the control's webpage is sitting on using some sort of method call from the control? Don't know if that was clear or not, but here's an example. Assume that the control is loaded in the page http://localhost/control.aspx. Now someone clicks a link in the control, how do I make the page change to http://www.google.com? Any help would be appreciated, thanks!
