title: Is Drag and Drop possible in Dgrid without using store
body: <p>i am not using store attribute for my Grid and want to implement DnD. Currently the row in my table are drag gable but throws an error when i drop the dragged row. Below is the error.</p>
  
  <p>"Uncaught TypeError: Cannot read property 'get' of undefined" </p>
  
  <p>Dojo documentation mentions that, The store should be order-aware, supporting the options.before parameter on add() and put() calls to properly respond to DnD operations. </p>
  
  <p>So does it mean that DnD can only be implemented using store in Grid.</p>
