On my DNN 4.6.2 site, I am trying to add an ASP.NET AJAX popup (modal, hover, or animation--doesn't really matter) that shows a treeview site map which users can then expand or collapse, and when they click on a link it will redirect them to the page they clicked on.  When my treeview nodes expand the treeview does a postback to pull child pages under that node (rather than loading all nodes on page load, which would take a while).  I can get the treeview to appear in the popup successfully.

The issue I'm having is when the treeview does postback to pull back child nodes, the asp.net ajax popup always disappears (I've tried modal, hover, and animation).  I can get the tree to appear, but when clicking a node, the popup will not persist.

Any ideas on how to configure the popups to stay visible even during postback?

Thanks in advance!
