How to close jQuery thickbox from server side - I want to cause the thickbox (frame style) to be closed from a line in the server - when an action is done etc.

I use the thickbox to show a file upload dialog, and once the upload is complete, i wanna dismiss the thickbox from the server's code behind (just like it would do with the 'Close' or Esc key).

Also, when I do Reponse.Redirect it opens up in the thickbox, how can i redirect the entire thing to a new page.
