Hi,
At the title of the thread, if you use a confirm within the onDrop event of the treeview drag drop then the confirm dialog is shown twice. This behaviour has been seen in IE11 and Firefox 26. Google Chrome 31.0.1650.63 appears to work as expected.
The following fiddle can be used to reproduce the behaviour: http://jsfiddle.net/ciantrius/KpEej/
