在Winform报表中对文本框和表进行分组

BackGround：我正在使用Winforms通过Visual Studio 2012创建一个报表。我的报告包括2个表，两个表都在其上方带有文本框，并带有表名。我知道将表行分组在一起，您可以使用“保持在一起”属性，该属性解决了我原来的问题，即仅显示第一行，然后显示其余页面。

问题：但是，当我导出PDF时（例如，带有第一个表），它显示的文本框具有应有的表名，但该表没有显示3页。

问题：如何在报表中将控件保持在一起，而每个控件之间没有潜在的重叠或较大的间隔？

            Microsoft.Reporting.WinForms.ReportPageSettings rptPageSettings = report.GetDefaultPageSettings();

            string width = "";
            double tmp = ((double)rptPageSettings.PaperSize.Width) * .01;
            width = tmp.ToString("#0.00",System.Globalization.CultureInfo.InvariantCulture) + "in";

            string height = "";
            tmp = ((double)rptPageSettings.PaperSize.Height) * .01;
            height = tmp.ToString("#0.00", System.Globalization.CultureInfo.InvariantCulture) + "in";

            string topMargin = "";
            tmp = ((double)rptPageSettings.Margins.Top) * .01;
            topMargin = tmp.ToString("#0.00", System.Globalization.CultureInfo.InvariantCulture) + "in";

            string bottomMargin = "";
            tmp = ((double)rptPageSettings.Margins.Bottom) * .01;
            topMargin = tmp.ToString("#0.00", System.Globalization.CultureInfo.InvariantCulture) + "in";

            string rightMargin = "";
            tmp = ((double)rptPageSettings.Margins.Right) * .01;
            topMargin = tmp.ToString("#0.00", System.Globalization.CultureInfo.InvariantCulture) + "in";

            string leftMargin = "";
            tmp = ((double)rptPageSettings.Margins.Left) * .01;
            topMargin = tmp.ToString("#0.00", System.Globalization.CultureInfo.InvariantCulture) + "in";

            string deviceInfo = "<DeviceInfo><PageWidth>" + width + "</PageWidth><PageHeight>" + height + "</PageHeight><MarginTop>" + topMargin + "</MarginTop><MarginLeft>" + leftMargin + "</MarginLeft><MarginRight>" + rightMargin + "</MarginRight><MarginBottom>" + bottomMargin + "</MarginBottom></DeviceInfo>";

            Warning[] warnings;
            m_streams = new List<Stream>();
            report.Render("PDF", deviceInfo, CreateStream, out warnings);

            FileStream fs = new FileStream(filename, FileMode.Create);

            m_streams[0].Position = 0;
            for (int i = 0; i < m_streams[0].Length; i++)
            {
                fs.WriteByte((byte)m_streams[0].ReadByte());
            }

            fs.Close();
        }

谢谢！
