    Hi,

    In the attached is a grid layout. I have grouping on column Abbreviation. There is also sorting on Document Amount column (from the lowest to the largest).
    I would like to change the way group is sorted (programmatically). The group should sort base on aggregated values (sum of Document Amount column).

    AUT: 102,08  
    AIR: 592,98,
    ARU: 3 918,40 
    AKE: 4 750,00
    BER: 6 024,00
    ANG: 33 630,00
    ALBER: 124 729,22
    and so on...

    Is it possible?

    Hello Dominik,

    Thank you for writing.

    In order to change the order of your Groups using custom grouping, you must implement your own generic Group comparer and change the default one. The following forum post demonstrates a sample approach:

    I hope this information helps. Should you have further questions, I would be glad to help.
