    {
        GridTableView tableView = e.Item.OwnerTableView;
        e.Canceled = true;
        GridSortExpression expression = new GridSortExpression();
        expression.FieldName = e.SortExpression;
        if (tableView.SortExpressions.Count == 0 || tableView.SortExpressions[0].FieldName != e.SortExpression)
        {
            expression.SortOrder = GridSortOrder.Descending;
        }
        else if (tableView.SortExpressions[0].SortOrder == GridSortOrder.Descending)
        {
            expression.SortOrder = GridSortOrder.Ascending;
        }
        else if (tableView.SortExpressions[0].SortOrder == GridSortOrder.Ascending)
        {
            expression.SortOrder = GridSortOrder.Descending;
        }

        tableView.SortExpressions.AddSortExpression(expression);
