Adding Summary row to gridgroupingcontrol

[Rem Aza]

I tried going through sample code but I still cant figure out how to 

1)add summary row to the gridgroupingcontrol

2)Is it possible that in summary row only few numeric columns are summed up ? How can I select which columns to sum up

Thank you for your time
