Is there a method to insert a row into a StringGrid or do I have to shuffle all 
higher rows up 1?

Answer:

TCustomGrid has a very useful but unfortunately protected method named MoveRow. You 
can get at it using the cracker class strategy:

1   type
2     TGridCracker = class(TCustomGrid);
3   
4   {insert a line at row 5}
5   stringgrid1.rowcount := stringgrid1.rowcount + 1;
6   TGridCracker(stringgrid1).Moverow(stringgrid1.rowcount - 1, 5);


You first add a new empty line, then move it to the required position. This automatically moves all following lines one position down.
