Originally created by @justinasmussen on GitHub (Sep 18, 2021).

Collapsed by default: After I drag/drop a header to group a column I would like an option to have the all rows collapse.
Group Totals: A footer row for each group where I can show a total for a column with an option to show when collapsed.
Default grouping column: Specify a one or more columns to be grouped when the grid loads.

+1 to this! The new DataGrid is amazing, but having TotalColumn and the option to make the allowgrouping panel invisible would help a lot to many use cases when the hierarchy is implicit in the data.

Hey @mmauri,

Grouping is already available in Radzen DataGrid and you can check our demos for more info:
https://blazor.radzen.com/datagrid-grouping-api
https://blazor.radzen.com/datagrid-group-header-template
https://blazor.radzen.com/datagrid-group-footer-template

There are templates for group header and footers, you can add default grouping when the DataGrid is loaded and you can have grouped grid with disabled grouping changes.

Thanks Vladimir,
But the problem is once is collapsed, you cannot see subtotals on the same datagrid columns.
On this example:
https://blazor.radzen.com/datagrid-grouping-api

Imagine that you have a sales amount column, so you group by sales rep, to see the aggregated sales, you have to open and go to the footer.
Group Header, as far as I know only displays a text, and you can't aggregate data using the same grid columns,
which is not very user friendly as users expect to aggregate in the same column.

Thanks
