Login to Box from MVC application.

Hi , My application was designed to manage the documents through box. my application contains entitlement flow for user management same time user will be redirect into Box "https://app.box.com/api/oauth2/authorize" to get authorization. Now user feel he don't want redirect any where. So i want to design custom login screen in my application and get credentials from user and send it to box in the background then get authorized without redirect the user to Box. Is there any solution to achieve this in my MVC application
