Hello Ivan,

Yes, it is possible.

Check out the online documentation regarding this topic here:

http://www.telerik.com/help/windows-phone/raddataboundlistbox-features-itemreorder.html

Take a look at the Activaging Reorder Mode programmatically topic.

Hi Ivan,

Thanks for writing back.

There's an event which is fired when the reordering state is closed, i.e. when the reorder buttons are hidden and the visual state of the items is restored to normal.

This event is called ​ItemReorderStateChanged.

I hope this is helpful.

Hi Ivan,

Thanks for writing back.

You should be able to access this event. It has been added prior to Q1 2014.

As for the exception you are experiencing: this exception might occur if you are also enabling the Tilt Effect on the ListBox' items. The Tilt effect is not compatible alongside the Reorder functionality.

Let us know if you have additional questions.
