Examples

C#

            if (e.Area != ItemClickAreaEnum.Cell)
                return;

            bool fAscending = SetSorted(e.Cell.ColumnIndex);

            switch (e.Cell.ColumnIndex) {
            default: // column 0 and 1 are sorted based on the Text property
                if (fAscending)
                    sftTree1.ItemCollection.Sort(new SortAscending(e.Cell.ColumnIndex));
                else
                    sftTree1.ItemCollection.Sort(new SortDescending(e.Cell.ColumnIndex));
                break;
            case 2: case 3: // column 2 and 3 are sorted based on the TagObject property, interpreted as a long
                if (fAscending)
                    sftTree1.ItemCollection.Sort(new SortTagObjectAsLongAscending(e.Cell.ColumnIndex));
