Question

我想将带有CSS的Asp.Panel content(text, GridViews)导出到C＃.NET的PDF。我正在使用带有Asp.Panel的iTextSharp和RenderControl，但CSS不是以PDF格式呈现的。

如何解决此问题（使用iTextSharp（如果可能）或以其他方式）？

此代码生成PDF文件：

        StringWriter sw = new StringWriter();
        HtmlTextWriter htw = new HtmlTextWriter(sw);

        StringReader sr;
        string fileName = "C://pdf/GridView.pdf";

        var doc = new Document(PageSize.A3, 45, 5, 5, 5);
        var pdf = fileName;


        PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(pdf, FileMode.Create));


        doc.Open();

        HtmlPipelineContext htmlContext = new HtmlPipelineContext(null);
        htmlContext.SetTagFactory(Tags.GetHtmlTagProcessorFactory());
        ICSSResolver cssResolver = XMLWorkerHelper.GetInstance().GetDefaultCssResolver(false);

        cssResolver.AddCssFile(Server.MapPath("Content/PDFs.css"), true);
        IPipeline pipeline = new CssResolverPipeline(cssResolver, new HtmlPipeline(htmlContext, new PdfWriterPipeline(doc, writer)));

        XMLWorker worker = new XMLWorker(pipeline, true);
        XMLParser xmlParse = new XMLParser(true, worker);

        this.pnlTabs.RenderControl(htw);
        sr = new StringReader(sw.ToString());
        xmlParse.Parse(sr);
        xmlParse.Flush();
        doc.Close();

这是我想发送给PDF的ASP面板：

     <asp:Panel ID="pnlTabs" runat="server" CssClass="TeamTabs">

        <div class="repHeader">
            <div class="row">

        </div>


        <div class="row" style="padding-bottom:36px;">
            <div class="col9 col-first">

                <asp:GridView ID="gvDashRep_Right_second" runat="server"  ></asp:GridView>

如果要使用带有css的ITextSharp导出为pdf，还有一个额外的下载（XMLWorker）。您可以从here

获取XMLWorker

要将此设置为应用您的CSS，您需要执行以下操作

    StringWriter sw = new StringWriter();
    HtmlTextWriter htw = new HtmlTextWriter(sw);

    StringReader sr;
    string fileName = Server.MapPath("PATH TO PDF");

    var doc = new Document(PageSize.A3, 45, 5, 5, 5);
    var pdf = fileName;


        PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(pdf,             FileMode.Create));

        doc.Open();

        HtmlPipelineContext htmlContext = new HtmlPipelineContext(null);
        htmlContext.SetTagFactory(Tags.GetHtmlTagProcessorFactory());
        ICSSResolver cssResolver = XMLWorkerHelper.GetInstance().GetDefaultCssResolver(false);

        cssResolver.AddCssFile(Server.MapPath("PATH TO CSS"), true);
        IPipeline pipeline = new CssResolverPipeline(cssResolver, new HtmlPipeline(htmlContext, new PdfWriterPipeline(doc, writer)));

        XMLWorker worker = new XMLWorker(pipeline, true);
        XMLParser xmlParse = new XMLParser(true, worker);

        control.RenderControl(htw);
        sr = new StringReader(sw.ToString());
        xmlParse.Parse(sr);
        xmlParse.Flush();

用相关文件路径替换PATH TO PDF（保存文件的loacation）和PATH TO CSS（您的css文件所在的位置）。当我不得不这样做时，css文件必须是一个外部文件（.css）。

将Asp.Panel导出为PDF？
