title: Retrieving rows in DataView by its index
body: <p>I have a DataView, which has been sorted in some order. How can I retrieve the values using an index.</p>
  
  <p>Something like this:</p>
  
  <pre><code>if(dv.rows[0]["name"]=="xxx")  
  {  
    --- do something ---  
  }  
  else  
    --- something else ---  
  </code></pre>
