I want to ask you how to render a pdf in asp.net using c#.
so my web can show a pdf.
You can use Aspose.PDF or iText (there is a free version).
You can read about the licensing for iText for more information on the comment provided below.
One way is to generate latex from your application and then convert latex into pdf:

The nice thing about doing it this way is that you can write your views just like all your other views, except you use latex instead of html.
You can use the ReportViewer component (in "Local Processing Mode", so you don't need the SQL Server Reporting Services) to show a Report created in Visual Studio in a web page.
If you want the report to output directly as a PDF (instead of being shown in the ReportViewer control), you can use the technique outlined in this article to render the report on the server and then send the PDF stream to the web client:
How to render client report definition files (.rdlc) directly to the Response stream without preview
The advantage of this solution is that you don't need to use any third-party libraries.

I'm looking for a way to have server side rendered pdf from a html+css+javascript source. The idea here is to have a preview and report designer available on the client side using react components.
I've tried DinkToPdf that can render PDF from html pages, however it seems like only the top level component was mounted in the page when the PDF was rendered, even when enabling javascript in the renderer.
Client side pdf rendering using canvases is not an option since data can be easily tampered with.
I did this recently using wkhtmltopdf, which is a command line version of webkit (which I think Chrome is based on). I was able to load/parse and generate a graph using css/d3/rickshaw.
The basic process is:
Create the HTML using RazorLight
shell out to wkhtmltopdf with the generated html.
do something with generated pdf.
first of all let me give you the context. I've been asked to create a Silverlight reporting application which allows users to view tables/charts of data and then schedule these controls to be emailed (in pdf or excel format) at a later date when new data becomes available.
I have written an application to do this using webforms for a previous company, essentially the report generation was triggered via a service which executed the web application pages and i was able to generate pdfs from the html strings, however my new company would like a silverlight app and I'm not so sure whether it's possible.
I DO KNOW: That I can use WriteableBitmap to render an image of a report control (ok for PDF), for excel I can use the export to excel functions on various grids.
Questions:
Can I talk to a silverlight app from a windows service and execute methods on the app including rendering controls? (I have a feeling that the client side nature of silverlight may stop me doing this).
If i can execute methods, then i assume that i will be able to intercept an export to excel stream and create an attachment with the excel mime type (if not already set)?
Please don't hit me with "why don't you just use Reporting Services" argument.
I'd be grateful for any comments and guidance.
I think you may try ActiveReports to accomplish the task you are looking for . ActiveReports does come with a SilverLight report viewer,Windows Forms Viewer and a Web based viewer. ActiveReports also has the ability to create charts and lets you add custom controls to the report.About exporting capabilities ,yes ActiveReports lets you export reports to PDF,Excel,Tiff,RTF,Html etc even on the SilverLight environment.
You can find some information regarding this here:

The background right now is that I coded website for the client and as part of the website I have a service calling a webpage every 5-10 minutes to generate some PDFS that become available on the website. The PDFs just contain a data dump of a table that is displayed on the website.
The new requirements are to add a cover page and apply a color scheme to the PDF report which replicates the view on the website.
I'm unsure how to go about this using C# and VS2008 with the backend database being MySQL. I originally thought about creating a report and then somehow programmatically rendering and saving it as a PDF, but because we are using MySQL that throws out the possibility of using Sql Server Reporting Services. Is there any other open source and/or free solution that will allow me to create and design the report and then programmatically create and save as a pdf without any user interaction?
Your best bet is iText here. It supports creating pdf programmatically in java or C#. We use it where I work to do just this thing (also using MySQL on the backend). I also recommend buying the book. It has lots of good examples, and if you purchase the book, you get a pdf version of the book.
Try TCPDF. Though written in PHP, it has no external dependencies, has plenty of options and examples included. Works fast and reliable, no problems with fonts, etc.
jsreport supports exactly this kind of pdf generation. You first create a report layout and dynamic structure using html, css and javascript templating engines. Then you just send the data and invoke the rendering using c# classes.
This blog post should give you more info how to do it.

I want to know how I can view a PDF through a C# .net desktop App. I am trying to create a application to view PDF using visual studio 2008
There is a pdf reader libraries called iText(iTextSharp). But it didn't help me
You can host a ie web browser control in your application and that will allow the user to view a pdf if they have a reader installed.
I can provide an example if you tell me whether you are using WPF or WinForms.
Drag WebControl on to you form
Set the path in code

I'm not sure what netbeans has to do with anything, but take a look at this question here How to render pdfs using C#
Essentially you need to get a 3rd party PDF viewer or write one yourself. There are quite a few around and would probably take a look at something like PDFViewForNet
iText isn't a PDF viewer.
If you want to read PDF documents in your application there are couple of Open Source PDF Libraries.
Does anyone know if the following is possible and if so what the best way of doing it is for free?
I am generating a PrintDocument in a project I am currently working on and displaying a print dialog box so a user can choose which printer they want to use etc. The is currently a windows form application and if a user wants to print to a PDF they can select to print to CutePDF or something similar.
However I am now putting a ASP.Net web frontend on the application and want to use the same code to generate the PrintDocument but want to print it to a PDF on the fly and serve it up via the Response stream in the format of a PDF download.
So my question is....How can I use the current PrintDocument and generate a PDF in memory from it??
Thanks
The System.Drawing code for a PrintDocument can be reused to generate a PDF document with ABCpdf .NET. See the System.Drawing example...
You would have to use a 3rd party component in order to generate the PDF. The following article has some links to some such components: Generating PDF Files from .Net
You're in a world of hurt if you think you're going to run the "same code" that deals with printers in both a forms app and an ASP.NET app.
You might be in luck, however, as it appears that PDFsharp + MigraDoc might be able to do this for you.
I think you will find there is not any tools that will take a PrintDocument as input and render a PDF as output. The only way to do what you want is to "print" the PrintDocument to a "PDF printer driver" that will generate PDF. Basically a virtual printer that will generate PDF instead of printing the actual output. There are a plethora of products on the market for that. A couple that are cheap and widely used are as follows:
Ghostscript with RedMon (open source/GPL or commercial licenses available)
Foxit Software's PDF Creator ($29)
You really should be looking at iTextSharp (it is mentioned on the iText.NET page recommended earlier)
http://itextsharp.sourceforge.net/
PrintDocument is meant for Windows Forms applications but is up and coming in SilverLight, see this video... http://silverlight.net/learn/videos/all/printing-api-basics/
If you wish to continue with the PrintDocument and a web application, I think SilverLight 4 (which is beta right now) is the only way to go, or your going to have to have a lite weight windows form application installed locally for the end user that maybe uses web services.
iTextSharp is a great tool for generating PDFs with .NET on the Internet. I highly recommend it; I've used iText with Java...and have been using iTextSharp for the past few years.
There are several ports of iText for .NET (A very popular open-source PDF library for Java).
