By default, SfDataGrid groups a column in the sorted order. However, you can group a column in the actual order without sorting the groups in SfDataGrid by removing the grouped column from the SfDataGrid.View.SortDescriptions in the SfDataGrid.GridViewCreated event.
Please refer the below code example to group a column in the actual order without sorting.
Note: In case, if you are applying grouping in runtime, then you have to apply the same logic of removing the grouped column from SfDataGrid.View.SortDescriptions after applying grouping to achieve this requirement.
