title: Visual Web Part in Sharepoint 2010 shows only XMLDataSource in GridView
body: <p>I created a new Visual Web Part in VS 2010 (using Sharepoint Server 2010), then dropped a GridView on the User Control.
  However when setting up the DataSource for the GridView, I only get XMLDataSource as an option.
  There is no option to create a SQLDataSource for instance.</p>
  
  <p>does anyone know how to get over this limitation in Visual Studio 2010?</p>
  
  <p>Thanks</p>
