getLocationRow() is used to return an integer value identifying the index of the target list row, to which the cursor was placed during the drag-and-drop operation. You can use the method in the ON DROP block when you need to get the index of the target row and modify or replace it by the dragged object.
You can also use the method within the ON DRAG_OVER block to cancel the drop, when the value returned by getLocationRow() does not meet specified conditions.
The method does not need any arguments.
