title: How to use data annotations for drop-down lists?
body: <p>In MVC3 data annotations can be used to speed up the UI development and validations; ie.</p>
  
  <pre><code>    [Required]
      [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
      [DataType(DataType.Password)]
      [Display(Name = "New password")]
      public string NewPassword { get; set; }
  </code></pre>
  
  <p>However, if for a mobile app, there is no field label, only a drop-down list populated from the database.  How would I define this in this way?</p>
  
  <pre><code>    [Required]
      [DataType(DataType.[SOME LIST TYPE???])]
      [Display(Name = "")]
      public string Continent { get; set; }
  </code></pre>
  
  <p>Is it better not to use this method for this?</p>
