title: Changing controls in Master Page in ASP.NET
body: <p>I am designing a website that uses a master page.</p>
  
  <p>I have a login text box and a label a user can use to login.  These controls are on my master page.</p>
  
  <p>However, even after the user logs in the text box and label asking for email id and password is displayed in next page where I redirect after succesful login.</p>
  
  <p>After a user, I want to hide the login label and text box and instead display a welcome user message.</p>
  
  <p>But I am not able to edit in next page where I redirect. how do I hide that?</p>
