Hi,
Thank you for using Syncfusion products.
You can achieve the desired behavior by adding the necessary column to the SortedColumns collections,
this.gridGroupingControl1.TableDescriptor.SortedColumns.Add("Id");
this.gridGroupingControl1.TableDescriptor.VisibleColumns.Remove("Id");
this.gridGroupingControl1.TableDescriptor.SortedColumns.Add("Values");
Please find the attached sample.
Regards,
Jisha
