Server grouping aggregate in Angular

[Rama Krishna]

Hello Fam,

I need to implement group aggregate in column's when the serverGrouping set to true.  Whenever the serverGrouping is true I cannot able to use the group aggregates I have bulk data so I need to group in server not client side.  I want to send the aggregates to server side whenever the api calls and get back the group aggregate calculations accordingly and then display in Angular. 

Thanks in advance!
