I am developing an ASP.NET 3.5 app that is protected with forms-based authentication. My RadTreeView is working great, except that when a user walks away from the browser and comes back after the session has timed out, if they click the plus (+) sign on any node in the treeview, they get a Javascript "Authentication Failed" pop-up. I'd like to find a way to handle this event and simply redirect them back to the forms authentication login page. What is the best way to do this? If it helps, we are populating the nodes on our treeview from a web service.
Thanks in advance,
Andrew
