Windows Phone Twitter OAuth too big web page

Hello friends.

I made the Windows Phone 8 OAuth client for the Twitter. I used this code: http://www.c-sharpcorner.com/Blogs/12824/latest-twitter-integration-in-windows-phone-8.aspx

The login works fine, but the problem is when I fill wrong username or password. The Twitter sends me back too big page where I have to fill the username or password again. It does not look nice. Do you have any idea how to solve it?

Thank you very much.
