I have a xamldatagrid with two lines in each row. If i drag a column to a new position, only the header and data in the first row is moved, data in the second row stays in the previous position as though no dragging have happened. Pasted below is the xaml. It is not the complete xaml, but i think this should be good enough to reproduce the issue. I can send you the complete xaml if needed.

I am also attaching the screen shot of the issue showing the screen before and after dragging the column. In addition to that, an empty row (space) is introduced between the first and second rows in one of the columns.

Any help is greatly appreciated
