Hi Alexandre,
Thanks for contacting Syncfusion forums.
QUERY: Incorrect presentation of group on grid with Paging
In grid, when we render grouping with paging, we peform grouping after paging only. Thus it has resulted in such a behaviour. If you need to perform grouping before paging, please check the below screenshot and sample,
You can use custom adaptor for achieving this requirement. In custom Adaptor, we can splice the paging query, process rest of the queries. After performing the other queries, we can process paging query.
Please check the below sample,
If you have further queries, please get back to us.
