Hi,
Thanks for your advice.
I could be wrong, but I think for a Grand Total, you want to use BottomFixed, not Bottom.
Thanks for your advice. I did try that but that also add a summary row on every group level. I wonder if I will need to use CreationFilter for that. If so how can I find the "last displayed" row? (since I'm using group by the last row can be different depending if the group is exanded or not)
