title: ExtJs Gridpanel store refresh
body: <p>I am binding ExtJs Gridpanel from database and add "Delete" button below my gridpanel. By using the delete button handler, I have deleted selected record on gridpanel. But, after deleting, the grid does not refresh (it is deleted from database but shows on grid because of no refresh).</p>
  
  <p>How can I refresh grid after delete handler ?</p>
