Question

我使用 MigraDoc 在c＃中从某些数据库表生成PDF文件。

我的主要问题是我添加的一些段落，它们无法安装到当前页面，因此被拆分为下一页，怎么能它被阻止了？我希望他们在一个页面（当前页面或下一页）。

        Document doc = new Document();
        Section section = doc.AddSection();
        Paragraph paragraph = section.AddParagraph();
        paragraph.AddLineBreak();
        paragraph.AddLineBreak();
        paragraph.AddLineBreak();

        paragraph.Format.TabStops.ClearAll();
        paragraph.Format.TabStops.AddTabStop("16cm", TabAlignment.Right, TabLeader.Lines);
        paragraph.AddTab();

        for (int i = 0; i < 20; i++)
        {

            Paragraph paragraphBody = paragraph.Section.AddParagraph();

            FormattedText ft = paragraphBody.AddFormattedText("This is a title", TextFormat.Bold);
            ft.Italic = true; ft.Font.Size = 11;
            ft.Font.Color = Color.FromRgbColor((byte)255, Color.Parse("0x1E9BC6")); //equal to rgb(30, 155, 196);
            ft.AddLineBreak();

            //--detail:---adding text---------------------------------

            String DetailText = "This is detail. This is detail. This is detail.This is detail.This is detail.This is detail.This is detail.This is detail. This is detail. This is detail. This is detail. This is detail. This is detail. This is detail. This is detail. This is detail. ";

            FormattedText ftdet;
            ftdet = paragraphBody.AddFormattedText(DetailText, TextFormat.NotBold);
            ftdet.Font.Size = 10;
            ftdet.Font.Name = "Arial";
            ftdet.AddLineBreak();
            ftdet.AddLineBreak();

            ftdet.AddText("Event Date: " + DateTime.Now.ToString("MM/dd/yyyy h:mm tt"));
        }

        PdfDocumentRenderer pdfRenderer = new PdfDocumentRenderer(false, PdfFontEmbedding.Always);
        pdfRenderer.Document = doc;
        pdfRenderer.RenderDocument();

        //Save the PDF to a file:
        string filename = "e:\\Report" +    DateTime.Now.ToString("yyyyMMddHHmmssfff") + ".pdf";
pdfRenderer.PdfDocument.Save(filename);

        Process.Start(filename);

段落在KeepTogether成员中具有Format属性。如果为true，则段落的所有行都保留在一页上还有一个KeepWithNext属性。如果为true，则段落的最后一行将与下一段的第一行位于同一页面上。

如果您有段落，只需编写如下代码：

paragraphBody.Format.KeepTogether = true;

另见：

表格单元格永远不会跨页面。因此，应用于表格单元格中的段落时，属性KeepTogether和KeepWithNext无效。
