Hi Prabakaran,

I am not sure that I understand your case. When you enable the drag/drop behavior of RadTreeView the items dragging should be allowed in all sibling elements and in a parent element different than the dragged item's parent. Can you please send me a small example demonstrating the observed behavior and a description of the expected result? This will help me to understand your scenario better and assist you further. Thank you for any provided information.

As a side note, keep in mind that dropping an item into his parent is not allowed by the drag/drop behavior. If you want to override this behavior you can override the DragDropManager's events which are used for implementing the drag/drop logic in RadTreeView. You can find such examples in our help documentation.
