title: SQL Server Compact does not support calls to HasRows property if the underlying cursor is not scrollable."
body: <p>What does this actually mean?</p>
  
  <p>I am stepping through some code and when I look at the properties of my datareader under the locals window in vs2010, the DR.HasRows shows an error:</p>
  
  <pre><code>HasRows '(DR).HasRows' threw an exception of   type 'System.InvalidOperationException'  bool {System.InvalidOperationException}
  
  base    {"SQL Server Compact does not support calls to HasRows property if the underlying cursor is not scrollable."}   System.SystemException {System.InvalidOperationException}
  </code></pre>
  
  <p>WHat is a cursor and how do I make it scrollable? :)</p>
