How to use itext 7 to generate a PDF from an HTML div and save it to a folder on the server in .net

I'm trying to create a CV builder that saves the CV edited by the user to a folder in my project for further processing of sending it through email, I have reached as far as using itext to create a PDF of an HTML div, but has no CSS or any of the text values I have returned from my database. Through some research i find that my problem could be solved by using itext 7 and an add-on pdfHTML but can not find any proper examples of how to use it with my ASP.NET code. Would really appreciate any help.
Bellow is the code for the on-click button event I use to generate the PDF
protected void ButtonDownload_Click(object sender, EventArgs e)
{
Response.ContentType = "application/pdf";
//Response.AddHeader("content-disposition", "attachment;filename=Panel.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
contentdiv.RenderControl(hw); //convert the div to PDF
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
string filename = base.Server.MapPath("~/PDF/" + "UserCV.pdf");
HttpContext.Current.Request.SaveAs(filename, false);
Response.End();
}
This picture shows the pdf result i get when i click the download button
And this is html page it is trying to convert
The text bellow the headings on the HTML page are Labels whose values are being set by retrieving values form a database

This is an example on how to use pdfHTML
This example is quite extensive, as it also sets document properties, and registers a custom Font.
public void createPdf(String src, String dest, String resources) throws IOException {
try {
FileOutputStream outputStream = new FileOutputStream(dest);
WriterProperties writerProperties = new WriterProperties();
//Add metadata
writerProperties.addXmpMetadata();
PdfWriter pdfWriter = new PdfWriter(outputStream, writerProperties);
PdfDocument pdfDoc = new PdfDocument(pdfWriter);
pdfDoc.getCatalog().setLang(new PdfString("en-US"));
//Set the document to be tagged
pdfDoc.setTagged();
pdfDoc.getCatalog().setViewerPreferences(new PdfViewerPreferences().setDisplayDocTitle(true));
//Set meta tags
PdfDocumentInfo pdfMetaData = pdfDoc.getDocumentInfo();
pdfMetaData.setAuthor("Joris Schellekens");
pdfMetaData.addCreationDate();
pdfMetaData.getProducer();
pdfMetaData.setCreator("JS");
pdfMetaData.setKeywords("example, accessibility");
pdfMetaData.setSubject("PDF accessibility");
//Title is derived from html
// pdf conversion
ConverterProperties props = new ConverterProperties();
FontProvider fp = new FontProvider();
fp.addStandardPdfFonts();
fp.addDirectory(resources);//The noto-nashk font file (.ttf extension) is placed in the resources
props.setFontProvider(fp);
props.setBaseUri(resources);
//Setup custom tagworker factory for better tagging of headers
DefaultTagWorkerFactory tagWorkerFactory = new AccessibilityTagWorkerFactory();
props.setTagWorkerFactory(tagWorkerFactory);
HtmlConverter.convertToPdf(new FileInputStream(src), pdfDoc, props);
pdfDoc.close();
} catch (Exception e) {
e.printStackTrace();
}
}
The most relevant line here is
HtmlConverter.convertToPdf(new FileInputStream(src), pdfDoc, props);
Which essentially tells pdfHTML to perform the conversion of the inputstream (specified by src), put the content in pdfDoc and use the given ConverterProperties (specified by props).

How to convert stringbuilder text and get pdf format file output in asp.net

I'm using Visual Studio 2008 and I need to convert some stringbulider text and get pdf format output file on button click event..
Following is sample stringbuilder text.
StringBuilder reqReport = new StringBuilder();
reqReport.Append("<li>Five copies of your latest Passport size.</li>");
reqReport.Append("<li>Your certificates, testimonials etc. (in original with one photocopy)</li>");
reqReport.Append("<li>Residence & Identity proof required in Bank account opening process as per RBI guidelines.</li>");
I tried using itextsharp..
string html = reqReport.ToString();
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
PdfWriter writer = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
System.Xml.XmlTextReader _xmlr = new System.Xml.XmlTextReader(new StringReader(html));
HtmlParser.Parse(pdfDoc, _xmlr);
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=Table.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Write(pdfDoc);
Response.End();
This creates the pdf file.. But when I try to open the file, it shows the the file is either corrupted or damaged and could not be opened..
Is there any other format to do the function..?
Thanks in advance...

save Pdf File in the particular folder instead of downloading

I am doing html to pdf file . Its Downloading instantly . I dont want download instantly. i want to save the file in my project folder once converted.
My C# Code
string html ="<table><tr><td>some contents</td></tr></table>";
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=WelcomeLetter.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
StringReader sr = new StringReader(table);
Document ResultPDF = new Document(iTextSharp.text.PageSize.A4, 25, 10, 20, 30);
PdfPTable Headtable = new PdfPTable(7);
Headtable.TotalWidth = 525f;
Headtable.LockedWidth = true;
Headtable.HeaderRows = 5;
Headtable.FooterRows = 2;
Headtable.KeepTogether = true;
HTMLWorker htmlparser = new HTMLWorker(ResultPDF);
PdfWriter.GetInstance(ResultPDF, Response.OutputStream);
ResultPDF.Open();
htmlparser.Parse(sr);
ResultPDF.Close();
Response.Write(ResultPDF);
Response.End();

For saving pdf file locally in your project folder you can use FileStream class like this.
FileStream stream = new FileStream(filePath, FileMode.Create);//Here filePath is path of your project folder.
Now use this stream instead of using Response.OutputStream when you create instance of PdfWriter object.
PdfWriter.GetInstance(ResultPDF, stream);
Now do not use Responce.Write as you don't want to download your file.And close your stream at end.
stream.Close();

I'm going to combine everyone's answer into one that you should be able to drop in and use. If this works, I would accept Manish Parakhiya's answer because that had the most important part.
First, I'm going to assume you are using a recent version of iTextSharp. I think 5.5.5 is the most recent version. Second, because of this, I'm going to restructure your code a bit in order to use the using pattern. If you're stuck on an older obsolete unsupported version like 4.1.6 you'll need to re-adjust.
Almost every tutorial out there shows you that you can bind directly the Response.OutputStream. This is 100% valid but I would argue that it is also a really bad idea. Instead, bind to a more generic MemoryStream. This makes debugging much easier and your code will port and adapt that much easier.
The below code includes comments about each of the changes and what things are actually doing. The top section is all about creating a PDF from a string of HTML. The bottom actually does something with it, including writing it to disk and/or streaming it to a browser.
//Will hold our PDF eventually
Byte[] bytes;
//HTML that we want to parse
string html = "<table><tr><td>some contents</td></tr></table>";
//Create a MemoryStream to write our PDF to
using (var ms = new MemoryStream()) {
//Create our document abstraction
using (var ResultPDF = new Document(iTextSharp.text.PageSize.A4, 25, 10, 20, 30)) {
//Bind a writer to our Document abstraction and our stream
using (var writer = PdfWriter.GetInstance(ResultPDF, ms)) {
//Open the PDF for writing
ResultPDF.Open();
//Parse our HTML using the old, obsolete, not support parser
using (var sw = new StringWriter()) {
using (var hw = new HtmlTextWriter(sw)) {
using (var sr = new StringReader(html)) {
using (var htmlparser = new HTMLWorker(ResultPDF)) {
htmlparser.Parse(sr);
}
}
}
}
//Close the PDF
ResultPDF.Close();
}
}
//Grab the raw bytes of the PDF
bytes = ms.ToArray();
}
//At this point, the bytes variable holds a valid PDF file.
//You can write it disk:
System.IO.File.WriteAllBytes("your file path here", bytes);
//You can also send it to a browser:
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=WelcomeLetter.pdf");
Response.BinaryWrite(bytes);
Response.Cache.SetCacheability(HttpCacheability.NoCache);
//Never do the next line, it doesn't do what you think it does and actually produces corrupt PDFs
//Response.Write(ResultPDF); //BAD!!!!!!
Response.End();

string tempDirectory = Session.SessionID.ToString();
string location = Path.Combine(Server.MapPath(
WebConfigurationManager.AppSettings["PathSet"].ToString()), tempDirectory);
if (!Directory.Exists(location))
{
Directory.CreateDirectory(location);
}
string fileName="abc.pdf";
filePath = Path.Combine(location, fileName);

Save pdf on a particular location using C#

Here is my C# Code :
protected void Button1_Click(object sender, EventArgs e)
{
string attachment = "attachment; filename=" + Session["pdf_name"] + ".pdf";
Response.ClearContent();
Response.AddHeader("content-disposition", attachment);
Response.ContentType = "application/pdf";
StringWriter s_tw = new StringWriter();
HtmlTextWriter h_textw = new HtmlTextWriter(s_tw);
Label1.Style.Add("font-size", "16pt");
Label2.Style.Add("font-size", "16pt");
Label3.Style.Add("font-size", "16pt");
h_textw.AddStyleAttribute("font-size", "8pt");
h_textw.AddStyleAttribute("color", "Black");
Panel1.RenderControl(h_textw);
Document doc = new Document();
PdfWriter.GetInstance(doc, Response.OutputStream);
doc.Open();
StringReader s_tr = new StringReader(s_tw.ToString());
HTMLWorker html_worker = new HTMLWorker(doc);
html_worker.Parse(s_tr);
doc.Close();
Response.Write(doc);
}
I want to save this pdf in this Path "H:\new\web\pdf_filename.pdf"
I am using ASP.Net C#.

You cannot specify where on the client machine the downloaded file will be saved.
If you want that type of functionality, you will need to run a plugin in the browser clientside that has access to the local file system.
The browser will take the filename you specify in your attachment header value as a suggestion, but even that can be overridden by the user when he actually saves it.
If you want to save it on the server, you only have to save it somewhere local (to the server) using any of the file-related methods or types.

PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(#"H:\new\web\pdf_filename.pdf", FileMode.Create));
try and see if this work, please make sure your authentication type is allow user to access that folder. Not everyone map H drive to same network path,

Save the generated pdf directly to the server directory folder without user prompt

A friend of mine gave me this task so I can learn advance programming a little bit easier. I am currently doing convertion of an html page to pdf using itext sharp and email the pdf as an attachement. My idea is to save the pdf first to the server machine in the folder name ToBeEmailedPDF folder before using it as an email attachment. The thing that bothers me is that this dialog as what you can see in the picture shows up using the code that I have below.
StringBuilder sb = new StringBuilder();
StringWriter tw = new StringWriter(sb);
HtmlTextWriter hw = new HtmlTextWriter(tw);
pnlPDF.RenderControl(hw); // pnlPDF contains the html contents to be converted to pdf
string htmlDisplayText = sb.ToString();
Document document = new Document();
MemoryStream ms = new MemoryStream();
PdfWriter writer = PdfWriter.GetInstance(document, ms);
StringReader se = new StringReader(htmlDisplayText);
HTMLWorker obj = new HTMLWorker(document);
document.Open();
obj.Parse(se);
// step 5: we close the document
document.Close();
Response.Clear();
Response.AddHeader("content-disposition", "attachment; filename=report.pdf");
Response.ContentType = "application/pdf";
Response.Buffer = true;
Response.OutputStream.Write(ms.GetBuffer(), 0, ms.GetBuffer().Length);
Response.OutputStream.Flush();
Response.End();
I know many of you out there knows a better way or know how to solve my problem. Please help me. Thank you!

There is big difference between client-side and server-side.
Response class can output contents to client machine, if you need to save file on server use something like File.WriteAllBytes (msdn) method

What you are trying to achieve is impossible for security reasons. Only the user can decide where he wants the attachment to be saved. Imagine if this was possible: you would then be able to save any kind of viruses into any kind of folders on the user's computer. As an alternative to showing the Save dialog you could open the PDF inline:
Response.AddHeader("Content-Disposition", "inline; filename=report.pdf");

You can save it using the following code:
PdfWriter.GetInstance(pdfDoc, new FileStream(context.Server.MapPath("~") + "/PDF/" + reportName + ".pdf", FileMode.Create));
