Starting a new Thread causes two paths of execution. The first path which
was the Request into your webserver completes the request and thus it's long
gone by the time your second thread tries to update a TextBox on the page.
You're starting to play with fire, so be careful until you've spent a lot
of time testing and understanding what you're doing.

There's a good article by Fritz that discusses how to create asychronous
pages which might help get you going down the right track:
