I have an ASP.NET updatepanel inside a Thickbox popup. What it seems to be doing is after submitting the form in the popup, I have it redirect, but it redirects inside of the the thickbox popup instead of closing and redirecting. If I remove the updatepanel, it works correctly (using target="_top" in the form tag) but I need an error to come up if something is wrong in the form thus the need for the updatepanel. Any ideas of what to do?
