Is it possible to disable a master page. What i want to achieve is this. I have a add_company page that uses masterpage. another page, addinvoice makes the user select a company in which the invoice should be sent to. I want a button for adding a company to popup the add_company page but without its masterpage. so i was wondering if it is possible the dissable the master page when loading the add_company page based on a request.query parameter?
