You can not redirect. Its a control. It is used as a part of a page.

You cannot do a Redirection to an UserControl ( ascx extension ). Usercontrol should be always rendered as part of the Parent WebPage where its added. So Make the Redirection( also add the querystring) to the WebPage ( Parent Page) where the UserControl is used/Added and fetch the QueryString Value .
