title: Purpose of using binding source?
body: <p>I recieve some information about using binding source but I really don't understand explicitly why using binding source related to datagridview.</p>
  
  <p>My questions are:</p>
  
  <ul>
  <li><p>Advantage and disadvantage of using bindingsource instead of removing the third person that is between the datasource and data gridview?</p></li>
  <li><p>What context are you supposed to use binding source?</p></li>
  </ul>
