Create PDF from HTML form results in C#

I have a project where I need to create an HTML form (no problem) and then create a PDF file from the results using C#.
I have done this before in PHP using FPDF but this one needs to be C#. Ideally I want to put the code into a user control and then stick it in an Umbraco website.
Can anyone recommend a good way to do this? PDF doesn't need to be fancy, it'll just display text, we aim to create a generic purchase order based on what the customer wants from the form, which can then be emailed to them to print off on headed paper.
Thanks

There are a couple of recent problems with iTextSharp. The most annoying is that in the latest version they've deprecated the HTML parser. So now everything has to work through the XMLWorkerHelper singleton and parses through ParseXHtml. I find this a real pain, since HTML pages which aren't well formed appear fine on browser, parse OK in the old method and now crash out with an exception. So it necessitates an extra step to make sure your HTML is well formed (as XHTML) first. If you are generating your HTML from an ASPX page, then using Server.Execute() to get the stream, then this might be useful to you for iTextSharp:

Be mindful that iTextSharp has a distinct lack of any decent documentation of the modern changes (being mindful that the Java iText documents don't translate perfectly to C#), it makes the learning curve far too long and steep for any practical use in short spaces of time. I've basically given up on that platform, though may just create a baseline system to get something working lean whilst I then learn another framework.
As a result, I'm looking at PDFizer and PDFSharp libraries. If I have some success, I'll report back.

here is a library for converting HTML to PDF

I like the PDFsharp library. Not sure how it would work for your needs, though.

Converting pdf to text

I need to create a C# or C++ (MFC) application that converts pdf files to txt. I need not only to convert, but remove headers, footers, some garbage characters on the left margin etc. Thus the application shold allow the user to set page margins to cut off what is not needed. I actually have already created such an application using xpdf, but it gives me some problems when I am trying to insert custom tags into the extracted text to preserve italics and bold. Maybe somebody could suggest something useful?
Thanks.

There are shareware and freeware utilities out there. Try fetching their source code, or perhaps use them the way they are.
A public version of the PDF specification can be found here: Adobe PDF Specification
PDF Shareware readers can be found: PDF Reader source code # SourceForge

Please look at Podofo. It's a LGPL-licensed library that has many powerful editing features. One of it's examples, txt2pdf IIRC, is a good start: it shows basic text-extraction; From there you can check if pre (in pdf engine) or post (in text) filtering suffices to your goals. I didn't get to use Pdf Hummus, but it's supposed to have these capabilities too, although it's less straightforward.

Generating PDF Report from database in C#, specifically ASP

I need to generate a high quality report based on information in a SQL Server database, and I want very explicit control of the layout and appearance from inside C#.
I have several choices that I know of that are already being used for various other reports at our company:
1) SQL Server's built in Reporting Services
2) Adobe Forms
3) Crystal Reports
This information I need as PDF directly parallels what is already being displayed in the user's web browser as HTML, so creating a print stylesheet and converting the browser body to PDF is an option as well.
So this creates option 4:
4) JavaScript convert HTML to PDF (my preference at this time)
Does anybody have a recommendation as to which approach I should take, or even better an alternative? All the choices seem pretty horrible.

I've used iTextSharp with very good results. It is an open-source .NET port of a java library. It works really well for creating PDFs from scratch. Remember that editing PDFs will always be hacky with any library, because PDF is an output format, not a read-write format.
Provided your HTML is fairly clean (remove javascript postbacks, anchors, ...),the iText HtmlWorker can convert HTML to PDF, if you prefer that route.
HTML to PDF in using iTextSharp:
Document doc = new Document(PageSize.A4);
HTMLWorker parser = new HTMLWorker(doc);
PdfWriter.GetInstance(doc, Response.OutputStream);
Also here.

Use SSRS, it has a built in PDF rendering mode.

I have used two other PDF report libraries with great success; Active Reports and Telerik Reporting. Personally I prefer the latter when it comes to programmatic control of layout and such.

Take a look also at the DevExpress Reporting (non-free 3rd party tool):
Overview
Online Demos
Documentation

Yes, you should use the best tools to get the best solution. The best tool in this case probably is SSRS.
But that's just looking at the capabilities of the tool.
Don't forget to look at your own capabilities!
My story: I know SQL, I know C#. (Both intermediate, I'm not a guru.)
Then I lay my hands on SSRS. And burnt them, once, twice, etc.
At the end, there was a nice result. So burning your fingers is not a wrong thing to do.
But first try to pull your html through an html to pdf converter (demo version) and see if the result it serves your needs.
Currently I'm using both:
SSRS for creating invoices, because amounts have to be transported from one page to the next
Winnovative to generate documents that only need page numbers

I would suggest using .Net ReportViewer control in local mode (no report server required). It works in both webforms and winforms. You create a client-side report (.rdlc) file (which contains all the visuals as well as placement of data fields), link it up to the ReportViewer, and supply the data (DataTable or collection of objects, as long as the fields match, it doesn't matter). In client mode it supports exporting to pdf and excel (and Word too? don't remember). By default these done by a dropdown in the control itself however you can programmatically export to any of the supported formats as well. You'll end up with a byte array you can shove into a file stream.
Basically you get most of the good parts of SSRS without all of that backend complexity. There should be a ReportViewer folder in %programFiles%\Microsoft Visual Studio 10.0\ReportViewer - but versions exist for 2005 and 2008 as well. Check out http://gotreportviewer.com/

I think the 4th option is the best. In this case you don't need to change either layout of the HTML page or a layout of PDF, if one of them has been changed.
It is also more convenient making a nice design via HTML than programmatically via C# :)
Take a look at WebToPDF.NET which is a .NET component written in C# that converts HTML to PDF. The converter supports HTML 4.01, XHTML 1.0, XHTML 1.1 and CSS 2.1 including page breaks, forms and links. It passes all W3C tests (except BIDI).

You can use Fast Report it's good tool and i has a free version

Programmatically find and replace text in pdf

I'm trying to create a web script that will allow me to alter PDF templates that I have uploaded and re-output them. I have tried Zend already which allows me to write to a PDF but that means leaving the PDF blank in certain space which is to primitive for what I need. PDFFlip was not any better.
We need to implement functionality so we can remove content from the PDF as well as remove and replace. I have looked at CAM::PDF and changepagestring.pl but I'm not sure it's up to the job. I was hard pressed to find any real usage examples and Perl is not a language I have used before.
This is for a web project but I am flexible with the language we use, ideally PHP or ASP.NET C# would be great. Preferably not Java unless there is no other way.
I should also point out that I looked through the FoxitReader SDK without any luck. I never tried to implement it but I found no mention of find and replace like functionality.

You can tinker with PDF text but it is not straight-forward just to search and replace. The text is designed as an end-file format not for easy editing. I wrote a blog post explaining some of the issues at http://pdf.jpedal.org/java-pdf-blog/bid/12670/PDF-text

May be as workaround it's better to hold and fill in templates in some format that is more convenient for editing? E.g., you can keep your templates as Microsoft Word templates and then export them to PDF after filling. This thread may be useful on this way.
PDF file format isn't quite appropriate for editing.
Alternatively, you may prepare your templates as PDFs containing form fields. In this case filling of form fields is common and well-known task and there a lot of pdf components for this.

Best way to print Invoices, Pick Tickets etc

Well, heres my scenario.
Client/Server winforms application with SQL Express as the DB. I need to be able to print invoice, packing slips etc..
i would like the customer to be able to modify the invoices. ie. be able to put their logo or change font sizes etc...basically format the display.
Things i have considered so far are.
1) Use a template engine (similar to codesmith or mygeneration) and use templates that output HTML. Then print the html page.
2) Use ReportViewer in local mode. I've heard that users can download a plugin for web dev express and edit the local report files. can anyone confirm this?
3) Use Reportviewer in remote mode.
I don't have much experience with ReportViewer so I'm not sure if i should use local or remote mode as well.
Those of you that have done this kind of thing before whats your recommendation?

After just completing a project with it, I would heartily recommend iTextSharp to create your invoices and other forms as PDFs. In addition to creating PDFs from scratch, you can also use it to fill in PDF forms and/or templates created with Acrobat (or even MS Office/OpenOffice). And it's free.
It's pretty easy to use in Windows apps or in ASP.Net applications. Most of the documentation and the books on it (iText in Action, for example) are about the original Java version, iText. However, there are tutorials and example code on the conversion process and, for the most part, all of the functions and libraries work the same in the .Net version, so adapting the book and reference code has been no problem.
I definitely learned the hard way that HTML and CSS are great for browsers (well, great except for the "every browser interprets it different" problem), but horrible for trying to generate consistent, attractive, and precise printed output and forms.

I'm personally using Aspose Words: they use word documents as templates, and I'm using Words bookmarks function to mark and retrieve the fields I need to fill.
Aspose works nicely with Tables (ie: you can add lines to a table, etc...) and sees Word documents as XML documents. You can then save the document as MSWord or PDF.
I wouldn't say it's the greatest library in the world, but it's definitely worth having a look :)

you can use Crystal Report for this. But first you need to scan the INVOICE and save it as an image,
Next is, on your crystal report, export the image on to it, and DRAG the fields to where they must print on the invoice (IMAGE SERVES AS YOUR GUIDE). Then after everything has been set-up, DELETE THE IMAGE and try it.
hope this helps.
