title: What to use for a datagrid with a lot of data?
body: <p>Found this interesting interview question:</p>
  
  <p>You need to display the sales data for your division for the past 5 years in a DataGrid on a Web Form. Performance is very important. What would be the best strategy to use in retrieving the data?</p>
  
  <ul>
  <li>a)Use a DataReader object to retrieve
  the data for the DataGrid.</li>
  <li>b)Use a DataSet object to retrieve the
  data for the DataGrid.</li>
  <li>c)Use a simple select statement as the
  data source for the DataGrid.</li>
  <li>d)Use a cached XML file as the data
  source and retrieve the data with a
  DataSet.</li>
  </ul>
  
  <p>My answer is c) but I am not too sure
  Can anyone point me to the right answer and explain it to me please
  Thanks</p>
