print only one row with its hierarchy

how can i print only the currently selected line including its hierarchy ?
so not all lines of the grid dgvOrder but only a certain one !

my code
            GridPrintStyle style = new GridPrintStyle {
                PrintHierarchy = true
            };

            this.dgvOrder.PrintStyle = style;
            RadPrintDocument document = new RadPrintDocument {
                HeaderHeight = 50,
                HeaderFont = new Font("Arial", 16),
                Logo = Image.FromFile(@"Logo.png"),
                LeftHeader = "[Logo]",
                MiddleHeader = "",
                RightHeader = $"{Param.PrintProtocol.Order}\r\n{Param.PrintProtocol.Client}",
                ReverseHeaderOnEvenPages = true,
                FooterHeight = 55,
                FooterFont = new Font("Arial", 12),
                LeftFooter = $"Island: {Param.PrintProtocol.OperationIslandNo}\r\nKS: {Param.PrintProtocol.OperationCostCenter}\r\nOperation: {Param.PrintProtocol.Operation}",
                MiddleFooter = $"\r\n \r\n[Page #] / [Total Pages]",
                RightFooter = $"\r\n \r\nProtocol: {Param.PrintProtocol.OperationProtocolType}",
                ReverseFooterOnEvenPages = true,
                AssociatedObject = dgvOrder
            };

            RadPrintPreviewDialog dialog = new RadPrintPreviewDialog(document);
            dialog.ShowDialog();  

thanks !!
