How do you Change Group Sort Direction using Report Client

Question

It looks like there should be a sort direction property on the ISCRGroupOptions object but there is none. So how do you set the sort direction of the group?

Answer 1

I tried that and it did not work. Here's the code to change the grouping, note I also change the associated sort object. I did notice that if you go into the crystal reports designer and bring up the Record Sort Export and select the group's corresponding sort that the Sort Direction radio buttons are disabled. The question is how to change the sort direction shown on the Change Group Options dialog?
        public bool GroupModify(short GroupIndex, string TableName, string ColumnName, SortDirection SortDirection)
            bool result = false;
            if ((_ReportClient != null) && (GroupIndex >= 0) && (GroupIndex < this.GroupCount()))
                CrystalDecisions.CrystalReports.Engine.Group docGroup = _ReportDocument.DataDefinition.Groups[GroupIndex];
                ISCRField field = _ReportClient.DataDefController.FindFieldByFormulaForm(docGroup.ConditionField.FormulaName);
                if (field != null)
                    Group group = _ReportClient.DataDefController.GroupController.FindGroup(field);
                    if (group != null)
                        Group newGroup = group.Clone();
                        newGroup.ConditionField = FieldGet(TableName, ColumnName);
                        if ((newGroup.ConditionField != null) && (_ReportClient.DataDefController.GroupController.CanGroupOn(newGroup.ConditionField)))
                            _ReportClient.DataDefController.GroupController.Modify(group, newGroup);
                            result = this.SortSet(TableName, ColumnName, SortDirection);
            return result;
        public bool SortSet(string TableName, string ColumnName, SortDirection SortDirection)
            bool successful = false;
            if (_ReportClient != null)
                ISCRField field = FieldGet(TableName, ColumnName);
                if (field != null)
                    ISCRSort sort = _ReportClient.DataDefController.SortController.FindSort(field);
                    if (sort != null)
                        _ReportClient.DataDefController.SortController.ModifySortDirection(sort, CRSortDirection(SortDirection));
            return successful;
        public int GroupCount()
            int count;
            if (_ReportClient != null)
                count = _ReportClient.DataDefController.DataDefinition.Groups.Count;
            else
                count = 0;
            return count;
