title: Change the value in select list c#
body: <p>Good day,</p>
  
  <p>I am currently creating a select list like so:</p>
  
  <pre><code>  return new SelectList(db.RadioNetworks
                            .OrderBy(x =&gt; x.RepeaterName), 
                            "NetworkIdentifier", "RepeaterName");
  </code></pre>
  
  <p>Which enables me to populate a dropdown list with the "RepeaterName"</p>
  
  <p>How can i change this to keept he same key value, but I want a compound data field.</p>
  
  <p>so like</p>
  
  <pre><code>  return new SelectList(db.RadioNetworks
                            .OrderBy(x =&gt; x.RepeaterName), 
                            "NetworkIdentifier", "RepeaterName"+" - " + "startCode");
  </code></pre>
  
  <p>how can I do this?</p>
  
  <p>even if I have to loop through a list of Radio Networks and build the select list manually.</p>
