I think I am stupid. I searched now for 15 minutes, and found several different solutions for scrolling on datagrids, but none seems to work for me.

You should use the datagrid method
datagrid.ScrollIntoView(itemInRow);
or
datagrid.ScrollIntoView(itemInRow, column);
this way provides no messing around finding the scroll viewer etc.
