Try the following:

• Try using HttpContext.Current.Response.Redirect("url", false);
• Make sure you reference System.Web and add an imports statement for it
• Check that your form security is set to Full trust

I'm thinking this has to do with the form not having full trust and hence not being allowed to redirect anywhere.
