Q:

How do I determine which telerik RadListBoxItem is being dragged from the RadListBox?

I have a telerik radlistbox with several list items within. They each have their own text and are draggable. I make use of the radlistbox OnClientDropped method and want to obtain the text of the radlistboxitem that was dropped.
How can I do this?

A:

Found out how to do it.  I decided to approach it a little differently after thinking about it, but the same basic solution applies.  You can obtain the source item (what you're dragging/dropping) through the event args in a clientside method.  At that point all you need to do is grab the pertinent information (in my case, the text of the item being dragged/dropped).
The javascript involved:
function OnClientDragStartHandler(sender, e) {    
    var objType = e.get_sourceItem().get_text();
}

Thanks
