How Do I: Implement the Incremental Page Display Pattern using HTTP GET and POST?

This was a good tutorial, but as always us developers demand more functionality. I have tried to implement an ajaxtoolkit:TabPanel to run in my postTarget.aspx page for this example, however it will not run. As shown in this video, you can use ASP components in the page you want to load, but is there a way to use ajaxtoolkit components in your page you are loading from the Webrequest? Can we do partial postbacks from the content being loaded?
