itext sharp generated pdf should open in new tab in mvc c#

$(document).off("click", "#btnPreviewAndDownload").on("click", "#btnPreviewAndDownload", function (e) {
var QuestionPaperID = 1;
var SubjectCode = '#Model.Model.SubjectPapperCode';
window.location = "#Url.Action("PreviewAndDownloadQuestionPaper", "TeamCreation")?QuestionPaperID=" + QuestionPaperID + "&SubjectPapperCode=" + SubjectCode;
});
private FileResult CreateQuestionPaperPDF(List<CustomMainQuestionDTO> questionDTOList, byte[] byteDoc, MemoryStream memStream)
{
Document doc = new Document(iTextSharp.text.PageSize.A4, 70, 40, 70, 40);
PdfWriter writer = PdfWriter.GetInstance(doc, memStream);
Font fontH1 = new Font(Font.FontFamily.HELVETICA, 11, Font.BOLD);
doc.Open();
doc.NewPage();
Paragraph Heading = new Paragraph(questionDTOList[0].SubjectName, fontH4);
Heading.Alignment = Element.ALIGN_CENTER;
doc.Add(Heading);
foreach (var questionDTO in questionDTOList)
{
doc.Add(Chunk.NEWLINE);
if (String.IsNullOrEmpty(questionDTO.QuestionParentQuestionMappingID.ToString()))
{
MainQuestion(questionDTO, fontH2, doc, fontH1Bold);
}
else
{
SubQuestion(questionDTO, fontH2, fontH1, doc);
}
}
doc.Close();
byteDoc = memStream.GetBuffer();
string fileName = "QuestionPaper - " + questionDTOList[0].SubjectName + ".pdf";
return File(byteDoc, System.Net.Mime.MediaTypeNames.Application.Octet, fileName);
}
i have created and aligned the question paper format using Itextsharp and downloaded it.
it is downloading in window but unable to open in new tab? How i can open the generated PDF in new tab?

You can try using following code to generate your pdf it will display on your browser.
string filenm = "test";
Document doc = new Document(iTextSharp.text.PageSize.A4, 70, 40, 70, 40);
var fpath = Server.MapPath("~/PDFFiles/FunctionProspectus/");
PdfWriter.GetInstance(doc, new FileStream(fpath + filenm, FileMode.Create));
Font fontH1 = new Font(Font.FontFamily.HELVETICA, 11, Font.BOLD);
doc.Open();
doc.NewPage();
Paragraph Heading = new Paragraph("Test");
Heading.Alignment = Element.ALIGN_CENTER;
doc.Add(Heading);
doc.Add(Chunk.NEWLINE);
doc.Close();
string contentType = "application/pdf";
return File(Server.MapPath("~/PDFFiles/FunctionProspectus/") + filenm, contentType);
In one of my project i have used this and is working well.

If I'm reading the question correctly, you are able to create and return the PDF just fine, but it is causing the browser to navigate to the document instead of opening separately. The reason for this would be because you're changing window.location to the address of the action producing the PDF. One way to avoid this and simplify the code would be to use a hyperlink with the "target" attribute set to "_blank" instead of using JavaScript to open it. You could also use window.open instead of setting the location if you wanted to keep using the JavaScript solution. Both of these will either open in a new tab or new browser window depending on browser and user preference settings.

create multiple page pdf from asp.net mvc?

I was trying to create a pdf dynamically and send it by attaching in the mail.
This is my code and it works perfectly for me.
public ActionResult sendmail()
{
MemoryStream ms = new MemoryStream();
Document doc = new Document(PageSize.A4, 10f, 10f, 100f, 0.0f);
PdfWriter writer = PdfWriter.GetInstance(doc, ms);
doc.Open(); //open doc for editing
doc.Add(new Paragraph("First Paragraph"));
doc.Add(new Paragraph("Second Paragraph"));
writer.CloseStream = false; //important
doc.Close(); //build the doc.
ms.Position = 0;
SmtpClient smtpClient = new SmtpClient();
smtpClient.Host = "provider.com";
smtpClient.Credentials = new NetworkCredential("credentialmailid", "password");
MailMessage mailMessage = new MailMessage()
{
From = new MailAddress("from#gmail.com")
};
mailMessage.To.Add(new MailAddress("to#gmail.com"));
mailMessage.Subject = "Pdf attached";
mailMessage.Attachments.Add(new Attachment(ms, "pdfname.pdf"));
smtpClient.Send(mailMessage);
return RedirectToAction("index");
}
Now my issue is : Document that I have to send is a purchase confirmation . it will have 3 pages. Many headings and styles will be there in it.
also some values I have to pass dynamically like who purchased it and date like wise a lot datas should pass dynamically
How to do this? I thought to create an Html of pdf file to be send and use something like this add parameters dynamically...
string mailpath = Server.MapPath("~/Mail/HtmlOF_pdfToSend.html");
string mailbody = System.IO.File.ReadAllText(mailpath);
mailbody = mailbody.Replace("##CompanyName", "Bhavin Merchant");
mailbody = mailbody.Replace("##BusinessType", "Bhavin business");

Fist You have to add iTextSharp dll then u have to add some packages :
using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.text.html;
using iTextSharp.text.xml;
using iTextSharp.text.html.simpleparser;
then as per your question. you want to pass dynamically values so i post some syntax as example :
// Create a Document object
var document = new Document(PageSize.A4, 50, 50, 25, 25);
var output = new MemoryStream();
// Create a new PdfWriter object, specifying the output stream
var writer = PdfWriter.GetInstance(document, output);
// Open the Document for writing
document.Open();
Suppose you have header in your pdf documnet so syntax will be :
var logo = iTextSharp.text.Image.GetInstance(Server.MapPath("~/images/it.jpg"));
logo.SetAbsolutePosition(300, 750);
document.Add(logo);
If you want to add phrase:
Phrase titl = new Phrase("\nE-Ticket\n");
titl.Font.SetStyle(Font.BOLD);
document.Add(titl);
Add lines :
Phrase titl1 = new Phrase("--------------------------------------------------------------------------------------\n\n");
titl1.Font.SetStyle(Font.BOLD);
document.Add(titl1);
Change the style of text :
Here you can change the font style & color.
Phrase title = new Phrase("Booking Date-" + txtDate1.Text + "\n");
title.Font.SetStyle(Font.BOLD);
document.Add(title);
If you want to add pdf table:-dt is data table.
PdfPTable UserInfoTable = new PdfPTable(dt.Columns.Count);
PdfPRow row = null;
UserInfoTable.AddCell(--add cell----);
document.Add(UserInfoTable);
Close the Document - this saves the document contents to the output stream
document.Close();
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition", string.Format("attachment;filename=Receipt-{0}.pdf", "hello"));
Response.BinaryWrite(output.ToArray())
Here I paste some example code as your question.

You can add more pages to the document like this:
doc.Open(); //open doc for editing
doc.Add(new Paragraph("First Paragraph"));
doc.newPage();
doc.add(new Paragraph("This is a new page =)"));

itextsharp html to pdf

I want to change some HTML in a pdf. All my html is in HTML string but I don't know how to pass it in correctly within iTextSharp.
public void PDF()
{
// Create a doc object
var doc = new doc(PageSize.A4, 50, 50, 25, 25);
// Create a new PdfWrite object, writing the output to the file ~/PDFTemplate/SimpleFormFieldDemo.pdf
var output = new FileStream(Server.MapPath("t.pdf"), FileMode.Create);
var writer = PdfWriter.GetInstance(doc, output);
// Open the doc for writing
doc.Open();
//Add Wallpaper image to the pdf
var Wallpaper = iTextSharp.text.Image.GetInstance(Server.MapPath("hfc.png"));
Wallpaper.SetAbsolutePosition(0, 0);
Wallpaper.ScaleAbsolute(600, 840);
doc.Add(Wallpaper);
iTextSharp.text.html.simpleparser.HTMLWorker hw = new iTextSharp.text.html.simpleparser.HTMLWorker(doc);
StyleSheet css = new StyleSheet();
css.LoadTagStyle("body", "face", "Garamond");
css.LoadTagStyle("body", "encoding", "Identity-H");
css.LoadTagStyle("body", "size", "12pt");
hw.Parse(new StringReader(HTML));
doc.Close();
Response.Redirect("t.pdf");
}
If anyone knows how to make this work.. it be good.
Thanks
Dom

Please download The Best iText Questions on StackOverflow. It's a free ebook, you'll benefit from it.
Once you have downloaded is, go to the section entitled "Parsing XML and XHTML".
Allow me to quote from the answer to this question: RowSpan does not work in iTextSharp?
You are using HTMLWorker instead of XML Worker, and you are right:
HTMLWorker has no support for CSS. Saying CSS doesn't work in
iTextSharp is wrong. It doesn't work when you use HTMLWorker, but
that's documented: the CSS you need works in XML Worker.
Please throw away your code, and start anew using XML Worker.
There are many examples (simple ones as well as complex ones) in the book. Let me give you only one:
using (var fsOut = new FileStream(outputFile, FileMode.Create, FileAccess.Write))
using (var stringReader = new StringReader(result))
{
var document = new Document();
var pdfWriter = PdfWriter.GetInstance(document, fsOut);
pdfWriter.InitialLeading = 12.5f;
document.Open();
var xmlWorkerHelper = XMLWorkerHelper.GetInstance();
var cssResolver = new StyleAttrCSSResolver();
var xmlWorkerFontProvider = new XMLWorkerFontProvider();
foreach (string font in fonts)
{
xmlWorkerFontProvider.Register(font);
}
var cssAppliers = new CssAppliersImpl(xmlWorkerFontProvider);
var htmlContext = new HtmlPipelineContext(cssAppliers);
htmlContext.SetTagFactory(Tags.GetHtmlTagProcessorFactory());
PdfWriterPipeline pdfWriterPipeline = new PdfWriterPipeline(document, pdfWriter);
HtmlPipeline htmlPipeline = new HtmlPipeline(htmlContext, pdfWriterPipeline);
CssResolverPipeline cssResolverPipeline = new CssResolverPipeline(cssResolver, htmlPipeline);
XMLWorker xmlWorker = new XMLWorker(cssResolverPipeline, true);
XMLParser xmlParser = new XMLParser(xmlWorker);
xmlParser.Parse(stringReader);
document.Close();
}
}
(Source: iTextSharp XmlWorker: right-to-left)
If you want an easier example, take a look at the answers of these questions:
How to parse multiple HTML files into a single PDF?
How to add a rich Textbox (HTML) to a table cell?
...
The code that parses an HTML string and a CSS string to a list of iText(Sharp) elements is as simple as this:
ElementList list = XMLWorkerHelper.parseToElementList(html, css);
You can find more examples on the official iText web site.

export to pdf not working in asp.net

can any one help me export the pdftable in pdf . my file is not getting exported to pdf and it also not showing any error i have written a code below code for export to pdf but it is not working properly i have use itextsharp dll for writing the code
her is my code
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
Paragraph p, p1, p2;
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
string imagepath = GetImageUrl("images");
iTextSharp.text.Image gif = iTextSharp.text.Image.GetInstance(imagepath + "/Logo.png");
p2 = new Paragraph();
p2.Add(gif);
p2.Alignment = Element.ALIGN_LEFT;
pdfDoc.Add(p2);
p1 = new Paragraph(new Phrase(new Chunk(" INVOICE ", FontFactory.GetFont("verdana", 15, BaseColor.GRAY))));
p1.Alignment = Element.ALIGN_CENTER;
pdfDoc.Add(p1);
p = new Paragraph(new Chunk("\n"));
pdfDoc.Add(p);
pdfDoc.Add(table1);
pdfDoc.Add(table);
string str = "This is a computer generated invoice. Please contact MSWindowsCare billing for more information at billing#mswindowscare.com";
p = new Paragraph(str, FontFactory.GetFont("verdana", 7, BaseColor.GRAY));
p.Alignment = Element.ALIGN_CENTER;
pdfDoc.Add(p);
pdfDoc.Close();
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;" + "filename=SalesInvoice.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Write(pdfDoc);
HttpContext.Current.ApplicationInstance.CompleteRequest();

Do some debugging. First thing I would do is write out the pdfDoc to a file and check whether this actually is correct pdf or empty or something.
Basically replace:
Response.Write(pdfDoc);
with something putting it to the dile system then try to open it.
And then take it from there. THis helps you nail down the issue.
Never used PdfWriter but I think the line up may not write the bytes of the pdf as you think it does. The result would be an obvious error on the client, not on the server.

iTextSharp HTMLWorker ParseHTML Tablestyle and PDFStamper

Hi I have succesfully used a HTMLWorker to convert a gridview using asp.NET / C#.
(1) I have applied some limited style to the resulting table but cannot see how to apply tablestyle for instance grid lines or apply other formatting style such as a large column width for example for a particular column.
(2) I would actually like to put this text onto a pre-existing template which contains a logo etc. I've used PDF Stamper before for this but cannot see how I can use both PDFStamper and HTMLWorker at once. HTMLWorker needs a Document which implements iDocListener ... but that doesnt seem compatible with usign a PDFStamper. I guess what I am looking for is a way to create a PDFStamper, write title etc, then add the parsed HTML from the grid. The other problem is that the parsed content doesnt interact with the other stuff on the page. For instance below I add a title chunk to the page. Rather than starting below it, the parsed HTML writes over the top. How do I place / interact the parsed HTML content with the rest of what is on the PDF document ?
Thanks in advance
Rob
Here';s the code I have already
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 30f, 0f);
HTMLWorker htmlWorker = new HTMLWorker(pdfDoc);
StyleSheet styles = new StyleSheet();
styles.LoadTagStyle("th", "size", "12px");
styles.LoadTagStyle("th", "face", "helvetica");
styles.LoadTagStyle("span", "size", "10px");
styles.LoadTagStyle("span", "face", "helvetica");
styles.LoadTagStyle("td", "size", "10px");
styles.LoadTagStyle("td", "face", "helvetica");
htmlWorker.SetStyleSheet(styles);
PdfWriter.GetInstance(pdfDoc, HttpContext.Current.Response.OutputStream);
pdfDoc.Open();
//Title - but this gets obsured by data, doesnt move it down
Font font = new Font(Font.FontFamily.HELVETICA, 14, Font.BOLD);
Chunk chunk = new Chunk(title, font);
pdfDoc.Add(chunk);
//Body
htmlWorker.Parse(sr);

Let me first give you a couple of links to look over when you get a chance:
ItextSharp support for HTML and CSS
How to apply font properties on while passing html to pdf using itextsharp
These answers go deeper into what's going on and I recommend reading them when you get a chance. Specifically the second one will show you why you need to use pt instead of px.
To answer your first question let me show you a different way to use the HTMLWorker class. This class has a static method on it called ParseToList that will convert HTML to a List<IElement>. The objects in that list are all iTextSharp specific versions of your HTML. Normally you would do a foreach on those and just add them to a document but you can modify them before adding which is what you want to do. Below is code that takes a static string and does that:
string file1 = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "File1.pdf");
using (FileStream fs = new FileStream(file1, FileMode.Create, FileAccess.Write, FileShare.None))
{
using (Document doc = new Document(PageSize.LETTER))
{
using (PdfWriter writer = PdfWriter.GetInstance(doc, fs))
{
doc.Open();
//Our HTML
string html = "<table><tr><th>First Name</th><th>Last Name</th></tr><tr><td>Chris</td><td>Haas</td></tr></table>";
//ParseToList requires a StreamReader instead of just a string so just wrap it
using (StringReader sr = new StringReader(html))
{
//Create a style sheet
StyleSheet styles = new StyleSheet();
//...styles omitted for brevity
//Convert our HTML to iTextSharp elements
List<IElement> elements = iTextSharp.text.html.simpleparser.HTMLWorker.ParseToList(sr, styles);
//Loop through each element (in this case there's actually just one PdfPTable)
foreach (IElement el in elements)
{
//If the element is a PdfPTable
if (el is PdfPTable)
{
//Cast it
PdfPTable tt = (PdfPTable)el;
//Change the widths, these are relative width by the way
tt.SetWidths(new float[] { 75, 25 });
}
//Add the element to the document
doc.Add(el);
}
}
doc.Close();
}
}
}
Hopefully you can see that once you get access to the raw PdfPTable you can tweak it as necessary.
To answer your second question, if you want to use the normal Paragraph and Chunk objects with a PdfStamper then you need to use a PdfContentByte object. You can get this from your stamper in one of two ways, either by asking for one that sits "above" existing content, stamper.GetOverContent(int) or one that sits "below" existing content, stamper.GetUnderContent(int). Both versions take a single parameter saying what page to work with. Once you have a PdfContentByte you can create a ColumnText object bound to it and use this object's AddElement() method to add your normal elements. Before doing this (and this answers your third question), you'll want to create at least one "column". When I do this I generally create one that essentially covers the entire page. (This part might sound weird but we're essentially make a single row, single column table cell to add our objects to.)
Below is a full working C# 2010 WinForms app targeting iTextSharp 5.1.1.0 that shows off everything above. First it creates a generic PDF on the desktop. Then it creates a second document based off of the first, adds a paragraph and then some HTML. See the comments in the code for any questions.
