title: Key value pair as enum
body: <p>Can I have an enum which acts as a key value pair. </p>
  
  <pre><code>public enum infringementCategory
  { 
      Infringement,
      OFN
  }
  </code></pre>
  
  <p>If I select <code>Infringement</code> I should get "INF0001" and if I select <code>OFN</code> I should get "INF0002"</p>
  
  <p>Is it possible?</p>
