Thank you for posting a workaround, Jorik!
I found a workaround for this: NewRowPosition="Bottom" and Minheight="100", this will make the new row visible even if there are no records.
Is this fixed....cos if we use NewRowPoisition="Top" the newly added row goes to bottom of the grid,and as per user experience it looks as if its jumping to last row and user needs to scroll down to last row of the grid if there large data in the grid...
