Prevent RadListBox from selecting item when drag drop an item out

Hi,

I have RadListBoxes that represents categories. Each of these RadListBox contains items that can be dragged to another category. Only one item can be selected across all the RadListBox. When I drag an item from a category to an other, the category from where I drag set selected to an item that it contains. Is there a way to prevent that behavior because I would like that the dragged item stays selected.

I attached a sample solution that represent the situation : drag an item from category A to another category and the selected item should be the dragged item in the drop category.

Thank you,

Etienne
