title: Using a password text box in a DataForm with Silverlight
body: <p>Is there an idiomatic way to indicate that a field in this model should be a password text box:</p>
  
  <pre><code>public class User
  {
     [Required]
     public string Username { get; set; }
  
     [Required]
     public string Password { get; set; }
  }
  </code></pre>
  
  <p>If there isn't an idiomatic way to auto-generate a password text box, is there a better way than hooking into one of the auto generation events?</p>
