此代码确实将我的gridview导出为pdf,但部分文本被截断。什么是我在pdf文档中确定gridview / table的宽度?

GridView1.Columns[0].Visible = false;
    Response.ContentType = "application/pdf";

    Response.AddHeader("content-disposition", "attachment;filename=Equipment.pdf");
    Response.Cache.SetCacheability(HttpCacheability.NoCache);
    StringWriter sw = new StringWriter();
    HtmlTextWriter hw = new HtmlTextWriter(sw);
    HtmlForm frm = new HtmlForm();


    GridView1.Parent.Controls.Add(frm);
    frm.Attributes["runat"] = "server";
    frm.Controls.Add(GridView1);
    frm.RenderControl(hw);
    StringReader sr = new StringReader(sw.ToString());
    Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);//create a document object

    PdfWriter writer = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);//get a pdf writer instance

    pdfDoc.Open();//open the document
    XMLWorkerHelper.GetInstance().ParseXHtml(writer, pdfDoc, sr);//invoke XMLWorkerHelper.getInstance().parseXhtml(writer, document, new FileInputStream)

    pdfDoc.Close();//close the document

    Response.Write(pdfDoc);
    Response.End();

如果没有特定的HTML,很难重现您的确切问题。我首先看一下RenderControl生成的HTML。如果没有任何特定的width命令,XmlWorker将根据内容尝试将内容放到页面上。如果列中的所有文本/对象的最大长度为50,那么该列将基本上具有宽度(可能加上一些填充)。对每一列重复此操作,您就可以获得表格的宽度。如果它比文档宽,那么将通过包装文本来缩小列,直到它适合。
