title: Combining two results of datasets into one
body: <p>I have created a webservice which returns two datasets(return type) as results.
  Is it possible to combine two datasets results into one so that I can display it on one datalist? I try using <code>arraylist</code> but it returns nothing in <code>datalist</code>.</p>
  
  <p><code>GetDepartureFlightsDetails()</code> and <code>getDepartureFlights()</code> both returns a dataset values.</p>
  
  <p>Below is the method i use to retrieve the webservice results.</p>
  
  <pre><code>public ArrayList GetDepartureFlightsDetails(String departurecountry, String arrivalcountry, DateTime departuredate)   
  {
      DLSA datalayerTS = new DLSA();
      DLJS datalayerJW = new DLJS();
  
      ArrayList array = new ArrayList();
  
      array.Add(datalayerSA.GetDepartureFlightsDetails(departurecountry, arrivalcountry, departuredate));
      array.Add(datalayerJW.getDepartureFlights(departurecountry, arrivalcountry, departuredate));
      return array;
  }
  </code></pre>
