The datagrid has its own version of formattedHeight - dgFormattedHeight. What I usually do is create a locked group that just contains the datagrid (you may need to group the datagrid and a dummy object first and then delete the dummy object to create a group that just contains the datagrid). I then set the height of the datagrid to its dgFormattedHeight (realigning it to the top of the group if necessary) and scroll it with a mobile scroller control.

Actually your best bet is probably just to grab Monte's mergDataGridScroller control from the mergExt website...

http://mergext.com/controls/mergdatagridscroller/

...as it handles all of this for you :)
