title: Set Data Source to datatable that only exists in dataset.. not an actual table in database
body: <p>I created a datatable in my dataset (.xsd file) which I fill in code behind. This datatable doesn't correspond to an actual table in sql. When I set this datatable as the data source in crystal I get database logon error. </p>
  
  <p>As a work around I actually create this table in sql for the crystal to work.</p>
  
  <p>Is there a way of doing this without the above work around? </p>
