Listgrid grouping + updateData + local Datasource

[mike7778]

Hi Isomorphic,

I'm using smartgwt.jar version: v12.0p_2020-02-29

I'm using a Listgrid with a local Datasource.
For exemple, i will take 3 columns (Name, Surname,Age), grouping is enable on column "Age".

If i call grid.updateData(record), sort is launched if i modify column "Name" or "Surname".

In our case, sort is time consuming (and "grouping..." screen is unnecessarily displayed)

In datachanged method (in ListGrid.js), i see that you never use groupByFields for check if grouping is necessary for the updated record.

Is-it expected, a bug or an enhancement?

Thanks for your answer.

Custom grouping and or custom sorting means that we don't whether the current grouping would be changed only by a change to groupByFields. So this isn't a bug. It would be possible to make an enhancement that would allow you to explicitly declare that only a change to the current sort and group fields will actually affect grouping, so that in your corner case you could optimize the behavior.

I will be very happy if i can explicitly declare that only a change to the current sort and group fields will actually affect grouping.
I think this is a relatively common case.
