I'm trying to use iTextSharp to produce a PDF file from an Html TextBox type
control in ASP.NET.
The problem is that the external CSS file is being ignored. I have followed the
examples on your website but to no avail. None of the CSS is being applied.
I'm using
* Visual Studio 2010 (C#)
* ASP.NET Framework 4.0
* itextsharp.dll vers. 5.4.4.0
* itextsharp.xmlworker.dll vers. 5.4.4.0
* CSS version 3.0
My Textbox control contains the following (which render correctly on the
webpage they are displayed on before generating the PDF from it)...
<table class="Results">
<tbody>
<tr>
<th class="CaseNumber">Case Number</th>
<th class="AnimalName">Animal Name</th>
<th class="RegNo">Reg No.</th>
</tr>
<tr>
<td style="height:3px" colspan="4"><hr></td>
</tr>
<tr>
<td class="CaseNumber">27842</td>
<td class="AnimalName">Te Mania Modest M126</td>
<td class="RegNo"></td>
</tr>
</tbody>
</table>
The css file contains:
table.Results
{
margin-left:auto;
margin-right:auto;
width:95%;
/*horiz-align: center;*/
text-align: center;
border: none;
font-size: 6px;
font-family: Arial;
}
table.Results th
{
font-size: 11px;
text-align: left;
}
table.Results th.CaseNumber
{
color: red; /* To see if this CSS is applied */
width: 20%;
text-align: center;
}
table.Results th.AnimalName
{
width: 35%;
}
table.Results th.RegNo
{
width: 25%;
}
table.Results td
{
text-align: left;
}
table.Results td.CaseNumber
{
width: 20%;
text-align: center;
}
table.Results td.AnimalName
{
width: 35%;
}
table.Results td.RegNo
{
width: 25%;
}
The code is C#
FontFactory.RegisterDirectories();
var styles = new StyleSheet();
var doc = new Document(PageSize.A4);
var writer = PdfWriter.GetInstance(doc, outStream);
writer.PageEvent = new PDFHeaderFooter(doc, htmlFooter1Text, htmlHeaderText,
htmlFooterText, styles);
try
{
doc.Open();
var htmlContext = new HtmlPipelineContext(null);
htmlContext.SetTagFactory(Tags.GetHtmlTagProcessorFactory());
htmlContext.SetImageProvider(new ImageProvider(imageAndLinkRoot));
htmlContext.SetLinkProvider(new LinkProvider(imageAndLinkRoot));
var cssResolver = XMLWorkerHelper.GetInstance().GetDefaultCssResolver(true);
foreach (var styleFile in styleFiles)
{
try
{
cssResolver.AddCssFile(styleFile, true);
}
catch (Exception)
{
throw new Exception("Can't open CSS file: " + styleFile);
}
}
var pipeline = new CssResolverPipeline(cssResolver,
new HtmlPipeline(htmlContext,
new PdfWriterPipeline(doc, writer)));
var worker = new XMLWorker(pipeline, true);
var p = new XMLParser(worker);
p.Parse(new StringReader(htmlBodyText ?? String.Empty));
}
catch (Exception ex)
{
var errorMsg = String.Format(PdfErrorMsgTmpl, ex.Message);
//Display parser errors in PDF.
var paragraph = new Paragraph(errorMsg);
var text = paragraph.Chunks[0];
if (text != null)
{
text.Font.Color = BaseColor.RED;
}
doc.Add(paragraph);
// Let the calling routine know
throw new Exception(errorMsg);
}
finally
{
writer.CloseStream = false;
doc.Close();
}
I've checked in my VS2010 debugger and the cssResolver has found my CSS file
and loaded it.
Regards
Mike
