title: Lightswitch insert row in a grid (after selected row)
body: <p>Issue is that I have wrote a method to duplicate selected row in a grid.
  Method likes (Grid is binded to <code>my_query</code>):</p>
  
  <pre><code>Namespace LightSwitchApplication
  
      Public Class Assignacions_GR_a_DPT_o_IR_manuals
  
          Private Sub Dup_row_Execute()
              Dim mySelectedItem = Me.my_query.SelectedItem
              Dim newItem = Me.my_query.AddNew()
              newItem.someProperty_1 = mySelectedItem.someProperty_1
              ...
              newItem.someProperty_n = mySelectedItem.someProperty_n
          End Sub
  
      End Class
  
  End Namespace
  </code></pre>
  
  <p>All runs fine. But new row appears at the end of the grid insteat below selected item.</p>
  
  <p>My question:</p>
  
  <blockquote>
    <p>Is there a way to duplicated row appears just below source row?</p>
  </blockquote>
