Hi,

 

`GridCellsSettings.group.groupHeader` only works when set in <Grid />, doesn't work if set in <Column />.

This works:

<Grid cells={{ group: { groupHeader: GroupMyHeaderCustomCell } }} >

This doesn't work:

<Grid>
    <Column
        cells={{
            group: { groupHeader: GroupMyHeaderCustomCell }
        }}
    />
</Grid>

Can you please explain the difference?

 

Thanks,

Jie

Hi, Jie,

The faced behavior is related to the fact that currently, all custom cell types are sharing the same interface, but only some of them can be applied to the columns. For example, you can define cells.data both in the Grid and in the separate columns, but the group-related customisations will take effect only if they are define directly in the Grid.

We will make sure that we document it more precisely in order to explain that specific in details and avoid any misunderstandings on this matter.
