title: Loop through fields in rdlc report
body: <p>I have an Rdlc report
  In this report I have a field which takes its values by this expression</p>
  
  <pre><code>(Round(((First(Fields!Occurs.Value) / First(Fields!TotalDistance.Value))* 10000),2)
  </code></pre>
  
  <p>but in some cases (TotalDistance.Value) = 0  so the previous expression returns Infinity,
  So I need to get the next record in case of that field equals 0 , 
  If also next field equals 0 , I want to get the next one</p>
  
  <p>I looked for way of getting next record but didn't find
  I only found (First , Last) methods, 
  How can I do that ?</p>
