I am creating folders in tree structure like we have windows explorer.My requirement is that if I am dropping a node into another node and the target node already contains a node with the same name as of source node then the source node should be placed back to its original position.The checking of same node name takes place in the controller and it returns false if it's duplicate.At this moment, I want to move the node at it's original position.I have tried e.setValid(false) and e.preventDefault() but it's not working. Please provide me the solution.

Hello Naveen,
You could use the TreeView's drag event to check whether the node you are dragging over has an item with the same name as the dragged item. For convenience I prepared a small example here, I hope it helps.
