title: Getting element id from Kendo UI treeview drag and drop
body: <p>On the drop event you get back an object that allows you to get the source and destination elements, however I can't see anything available in these objects that helps me identify them uniquely against the datasource.</p>
  
  <p>When I originally databound all of these objects I set an id for each item, but that id is not available in the drop event source/destination elements.</p>
  
  <p>The documentation on the Kendo UI site only goes as far as explaining that there is source/destination objects, not how to do anything with them.</p>
  
  <p>I want to get the source and destination ids so that I can go to the database, remove the source and add it to the destination.</p>
