My Code is :

 

protected void btnExport3_Click(object sender, EventArgs e)
{
byte[] bytesArray = null;

StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
pnlPerson.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());

string filename = "PaySlip123";
string html = sw.ToString();
html = html.Replace("px", "");
html = html.Replace("
", "
");
html = html.Replace(" ", " ");

//Register a single font
FontFactory.Register(Path.Combine(System.Environment.GetEnvironmentVariable("windir"), "Fonts") + "\\ArialUni.TTF", "Arial Unicode MS");

using (var ms = new MemoryStream())
{
using (var document = new Document(PageSize.A4,0,0,0,0))
{
using (PdfWriter writer = PdfWriter.GetInstance(document, ms))
{
document.Open();
using (var strReader = new StringReader(html))
{
//Set factories
HtmlPipelineContext htmlContext = new HtmlPipelineContext(null);
htmlContext.SetTagFactory(Tags.GetHtmlTagProcessorFactory());
//Set css
ICSSResolver cssResolver = XMLWorkerHelper.GetInstance().GetDefaultCssResolver(false);
cssResolver.AddCssFile(System.Web.HttpContext.Current.Server.MapPath("~/PrintStyle.css"), true);
//Export
IPipeline pipeline = new CssResolverPipeline(cssResolver, new HtmlPipeline(htmlContext, new PdfWriterPipeline(document, writer)));
var worker = new XMLWorker(pipeline, true);
var xmlParse = new XMLParser(true, worker);
xmlParse.Parse(strReader);
xmlParse.Flush();
}
document.Close();
}
}
bytesArray = ms.ToArray();
}
Response.Clear();
MemoryStream ms1 = new MemoryStream(bytesArray);
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=labtest.pdf");
Response.Buffer = true;
ms1.WriteTo(Response.OutputStream);
Response.End();
}
