The data is grouped on the client column. There are 3 groups: 'client 1', 'client 2' and 'client 3' in that specific order.
Applying a sort on this column(ascending,descending) takes no effect, clients keep in the exact same order.
In my grid, client 3 is at the top, client 1 in the middle and client 2 at the bottom. I would like to order the groups alphabetically but nothing I try seems to work.
I am not sure, but probably you should try to use groupDataSorted:true parameter inside of groupingView. For the sorting will be used groupOrder parameters (can be 'desc').
