title: Extjs Grid - get exactly destination position after drag
body: <p>I have a 'gridpanel' example:
  <br>id
  <br>--
  <br>1
  <br>2
  <br>3
  <br>4<br>
  It can drop drag. When i drag 2 to after 3. It's say (drag 2 before 4).<br>
  i want get exactly destination position after drag that's not depending before or after.<br>
  (so above example, output's should 3) thanks</p>
  
  <pre><code>listeners: {
    drop: function(node, data, dropRec, dropPosition) {
       var dropOn = dropRec ? ' ' + dropPosition + ' ' + dropRec.get('id') : ' on empty view';
       Ext.example.msg("Drag from left to right", 'Dropped ' + data.records[0].get('id') + dropOn);
    }
  }
  </code></pre>
