Hi Poly,
We regret for the delay caused.
I have uploaded the sample in different location in which the MouseDown event has been handled in order to get the selected rows to drag and drop. The ParentRecord provided on the selection can be made used to the grid to move the rows according to the drag and drop.
Please refer the sample attached in the below location:
