What's the best way to render a chunk of HTML in an application? We have a rich text editor control (from Karamasoft) in a web page, and need to generate a PDF with records saved from the control (with custom page headers, page footers, and record headers) so I need to be able to render the html so it can be "drawn" onto the page to be saved as a pdf.... is there any staright forward simple way to do this?
HTML Renderer is a library of 100% managed code that draws beautifully formatted HTML.
Without using any libraries, you can use the Literal control that allows you to inject the HTML you wish to display to the user.
You may try PURE to render JSON data in HTML: http://beebole.com/pure/
Although this may be out of topic.
But then I'm interested on how do you convert the HTML in PDF.
What technical steps are involved?

I create application for read news, and I get content with server in the form of html code. I use standard WebView control for showing him, but it is not very well. Because this control you cannot change. And I founded HTMLTextBox but this control does not display youtube video. My question what control is best to use for this?
You have 3 solutions to display HTML :
Parse the HTML and display it with your own XAML. You could use the Html Agility Pack to parse the html you want.
Let someone parse the HTML for you and display it with a custom control like the HTMLTextBox you mentioned.
Let the browser parse the HTML for you and display it with the classic WebView. Note that you can add some css or js to enhance, improve or manage the html.
I'm using C# .Net and want to generate a random size HTML table into PDF. I have tried ExpertPDF and Essential Objects HTMLtoPDF but they seem to mess up on very wide tables.
Any tools or ideas to fix this?
These tools use html rendering engines like a regular browser. Then they take the rendered content and write it into a pdf. They don't know how to handle wide content (except for scaling it to fit into a pdf page).
You need to change your html (create a printer friendly version of your page that is not that wide) and feed the html to pdf converter something that it can chew.
I am building a large scale web application with many "print" requests a minute. We have dynamic content from an editor that I print out with other HTML elements. What is more efficient, rendering that html and then printing the html page or rendering a PDF server side and displaying that in an iframe to be printed?
With the multiple server side calls for rendering the images plus authenticating the user (and we also have a dynamic image header and footer dependent on the logged in user) would it be more efficient to render native PDF controls and then put a pdf in an iframe to print?
I was planning on using itext sharp or http://www.websupergoo.com/ for the rendering.
the app is a c# Web forms application.
As I see it in order to generate the PDF you need to generate the HTML. So by generating the PDF you are adding to the processing required not reducing it.
I've been pointed in the direction of ITextSharp, when I went to download the package from NuGet I noticed something called RazorToPDF only to discover unsolvable formatting issues due to the project no longer being supported.
After more research I was surprised to find there wasn't a similarly worded question as this on SO.
So guys, what's the best way to convert a HTML page/table in an MVC project to a PDF file?

Generally, print it to a PDF from the web browser on the client.
The thing is, by relying on the end-user perspective of the view in this case, you're also relying on the end-user rendering of that view. It's a step that should be removed from this particular equation entirely.
Keep in mind that there are fundamental differences between how an HTML page renders and how a PDF renders. The two aren't 100% interchangeable. A PDF has a static page size and elements are placed absolutely, whereas HTML has dynamic sizes and elements are placed in a flow layout. There are additional considerations such as client-side DOM manipulation that may take place in that view. "Rendering" it quickly becomes a browser-based activity, which is something you shouldn't really need to do server-side.
Instead of thinking of the PDF as an extra step following the rendering of the view, think of it as a view in and or itself, parallel to the other view. One requested action results in the HTML view, another requested action results in the PDF "view". As such, you design the PDF template how you want it to look and populate it with data (using something like iTextSharp) before returning the file contents to the client.
I have a bunch of HTML code that I need to display in a label/textbox in a windows app written in c#. It should be in such a way that the output shows the HTML formatted text, rather than the HTML code itself.
How can I do this?
Render your HTML in WebBrowser control. It has special events for document and you can iterate by tags like this Hope it will help you;)
Check out WebBrowser
There's a web browser control using IE's rendering engine to display HTML content. You might as well be able to do some simple parsing yourself and use a RTF control but that way you will be rather restricted.
If WebBrowser doesn't suit your needs you can check out these libraries with HTML label/control support
