title: Sorting unbound datagridview programmatically
body: <p>I need to sort the datagridview programmatically.  I googled a lot but nothing worked for me.</p>
  
  <p>Datagridview is not bound to any datasource.  Data is being added manually.
  My requirement is to sort it as when a 'Sort' button is pressed.</p>
  
  <p>Can anyone suggest me code in vb.net?</p>
