To add group by column, we normally drag column and drop it in the group by box area.
How do I achieve this functionality dynamically ?
You would use the SortedColumns collection, ensuring that you pass in 'true' as the third parameter of the Add method:
this.ultraGrid1.DisplayLayout.Bands[0].SortedColumns.Add("Column Key", false, true);
