            private void treeView_DragOver(object sender, DragEventArgs e)
            {
                Point newPoint = treeView.PointToClient(Cursor.Position);
                UltraTreeNode nodeAtPoint = treeView.GetNodeFromPoint(newPoint);
                if(nodeAtPoint == null)

                  return;

                if (nodeAtPoint == "whateveryouwanttoCheck")
                {
                    e.Effect = DragDropEffects.Move;
                }
                else            {
                    e.Effect = DragDropEffects.Copy;
                }
            }

     

    Keep in Mind that this method is called on every mousemove. The ultratree does sadly not support a "UltraTreeNodeDragEnter/DragLeave".
