Remarks
The GridControl supports data grouping by an unlimited number of columns. The GroupBy method groups data by the values of the specified column. If several columns are involved in grouping, the groupedIndex parameter specifies the grouping level.
Data rows are always sorted against the grouping columns. If data is grouped against a column which isn’t sorted, the grid automatically applies sorting in ascending order to this column.
