    Hi,

    I have a question about GridView group sorting problem.

    If I have some data like this:

    Group_Name | Group_Order

    T_group         |        1

    T_group         |        1​

    M_group        |        3

    M_group        |        3

    M_group        |        3​​

    J_group         |         2

    J_group         |         2 

    I want to GridView grouping by "Group_name" but the group order column is "Group_Order".

     

    Do you have some good idea?

    Thank you

    Hello haochen,

    You can customize the sorting expression of the groups by overriding the GreateGroupSortExpression of a group descriptor. More information can be found in the "About Reorder by SumFunction Value" forum thread.
