Creating PDF docs in Asp. Usually either for reporting or, more often, for having printable friendly documents invoices, receipts etc. I used to design a Crystal report document and then evaluate it and convert it to PDF in the web application. The desing part was ok but what really bothered me was the problems that often came up with deploying it. Version mismatches could really turn it into a nightmare.
Lately I came up using the excellent wkhtmltopdf tool to convert html content to PDF. It uses the WebKit engine used by Chrome and Safari to render html. The nice thing about it is that I can leverage my knowledge of html and css to obtain a good looking PDF and also it's quite fast.
It's a exe file not a dll library a dll actually exists but it's not managed code and it has some problems related to usage in a multi-threaded app. It has to be executed from the Asp. Another downside is that it requires some work to set it up: copying exe and dll files in the web app solution, make sure they get copied over when building and publishing and some config stuff needed to make it access authenticated actions.
It seemed to me a perfect candidate to become a Nuget package. It was fairly easy to build it, except some quirks when trying to modify package properties. With Rotativa all it takes to print a PDF is: 1. Install using the Nuget package manager search for Rotativa or, more conveniently, with the package manager console, typing: Install-Package Rotativa 2. Writing a controller action to return a view representing the desired PDF output.
This means just coding as usual to serve the data as regular MVC action. When the html is ok you can just setup a special action returning a custom ActionResult: ActionAsPdf.
It can accept a parameter with other route data, in this case we are defining the invoiceId parameter. You can specify the name of the file being returned using the FIleName property. To link to the PDF file in other views you just have to insert a regular link to the PrintInvoice action.
Something like Html.

Any solution for this? Hi Julian, just tried the latest version of the Acrobat Reader with Rotativa and it seems to work Are you able to open other pdf files? Does it work from computers with previous versions of Acrobat reader? Could you send me a copy of a sample pdf you are not able to open? Thanks, Giorgio. You are trying to install this package into a project that targets '.Post a Comment. These versions are missing some features, you can find out if your version of wkhtmltopdf is one of these by running wkhtmltopdf --version if your version is against an unpatched QT, you can use the static version to get all functionality.

In header and footer text string supplied to e. Headers and footers can also be supplied with HTML documents. As an example one could specify --header-html header. Outlines Wkhtmltopdf with patched qt has support for PDF outlines also known as book marks, this can be enabled by specifying the --outline switch. The --outline-depth switch can be used to bound this.
Page Breaking The current page breaking algorithm of WebKit leaves much to be desired. Basically webkit will render everything into one long page, and then cut it up into pages. This means that if you have two columns of text where one is vertically shifted by half a line. Then webkit will cut a line into to pieces display the top half on one page. And the bottom half on another page. It will also break image in two and so on. If you are using the patched version of QT you can use the CSS page-break-inside property to remedy this somewhat.
There is no easy solution to this problem, until this is solved try organising your HTML documents such that it contains many lines on which pages can be cut cleanly. Page sizes The default page size of the rendered document is A4, but using this --page-size optionthis can be changed to almost anything else, such as: A3, Letter and Legal.
This static binary will work on most systems and comes with a build in patched QT. Unfortunately the static binary is not particularly static, on Linux it depends on both glibc and openssl, furthermore you will need to have an xserver installed but not necessary running. You will need to have different fonts install including xfonts-scalable Type1and msttcorefonts.

Compilation It can happen that the static binary does not work for your system for one reason or the other, in that case you might need to compile wkhtmltopdf yourself.In the past when I needed to create a PDF report in.
You may need to consider the old style tables layouts rather than complex CSS, but give it a go, you may be surprised with the results.
If your page has any dynamic drawing, like graphs, you may want to do a few small tests before committing yourself too much as you may need to create actual file images and import them in. You can call Views, PartialView, even Actions and instead of displaying them in your browser you will get the standard modal to open as a PDF or save to a file. Using a Partial View is almost identical and provides a good method of reusing the code for both browser and PDF:.
When you use SSRS reports you get pampered with the automatic features which you may think of as basic, such as paging, headers, footers, numbering, etc. An example is when I searched Google how to insert a simple page break and I was surprised to find how many where asking the same question and having difficulty. Given all that, I think I will be using Rotativa often because I like the simplicity and convenience of the drop-in solution it gives.

I thought it was. I will send a pull request once I cleanup the code and push it to my repo. I was trying to verify it with the latest code from repo and it's working fine now. May be I overlooked something. Closing this issue.
Ok Chanduthanks. I have the latest Rotativa from Nuget version 1. I downloaded the Windows installer for wkhtmltopdf from the project site, and overwrote the Rotativa dlls and exe with those found in the installer. After doing this the page-break issues were solved. There is a clear size difference between the wkhtmltopdf. So I'm guessing somewhere along the way the exe has not been correctly upgraded at least maybe not the Nuget side?
The fact that the exe file doesn't show version number doesn't help, I was pretty sure I downloaded the last available. In fact I checked that files have different sizes, so I just updated both this repo, and the nuget package, with the version currently on the download page 8.

The default OutputArea has the following values on a letter size paper:. This creates a margin of 1 inch on all sides because letter size is 8. The following code would change the margins to 0. Pdf does not have a direct option for page orientation.
For example, the following code uses A4 paper in landspace instead of in portrait orientation:. Pdf supports page CSS at-rule. You can either automatically or manually apply page at-rule. The page at-rule will not be automatically applied when either of the above condition is not met. However in that case it can still be applied manually. The following code demonstrates how to apply page at-rule manually:. Visual Basic. Left 1 inch Top 1 inch Width 6.

All rights reserved.Many developers are faced with the task of creating PDF reports for web applications, quite a natural request.
I would like to bring to your attention my experience with this task when using the Rotativa library for generating reports. This, in my opinion, is one of the most convenient libraries for such a goal in its segment, but when using it I encountered several not obvious points that I want to talk about. To be completely honest, I would like to share with you the set of rakes that I stepped on in the process of integrating this library, no doubt fast and very convenient.
How to generate PDF in ASP.NET MVC
In this article I will not deal with the issue of choosing a library. Each may have their own reasons for using this or that. I chose Rotativa, because it had everything necessary to meet customer requirements at minimum cost to set up.
Besides her, I tried three or four options. Web application on ASP. NET version 4. Other features do not matter in this context, with the exception of deployment. It is assumed that the deployment will occur on Azure.
This is important because some other libraries for example HiQPdf do not transfer installations in certain Azure configurations, this is documented. The report itself is simply a set of some tables, fields and graphs for demonstration to the user. Both versions assume the presence of a menu with navigation through report sections, the presence of tables, some graphics colors, text size, borders. I did not describe the routing here, but it is assumed that you have configured the routes to correctly call both controllers.
Interestingly, this library itself is essentially a wrapper over the well-known console utility wkhtmltopdf. The speed of work at altitude, you can put on Azure - will work. But there are features that we will talk about.
It is logical to assume that the customer will print the PDF and will want to see the page number. It's all very simple, thanks to the creators of Rotativa. According to the documentation Rotativa, through the parameter, CustomSwitches you can specify the arguments that will be passed to the utility itself wkhtmltopdf. Well, online tips are generous with examples.
The following call adds a number to the bottom of each page:.Convert HTML to PDF in crn.rotatemp3kaduna.pw Core in Just 5 Minutes
It works great. The page number itself is transmitted using a parameter [page]such parameters will be replaced by specific values. Large multi-page reports require content and page navigation in PDF. This is very convenient and simply vital when the number of pages in the report exceeds one hundred. Accordingly, it is necessary to provide for the proper use of these header tags in your HTML template.
But in reality, the addition --toc does not lead to any consequences. As if the parameter was not. However, other parameters work. Thanks to a post on some forum, I found that this parameter should be passed without hyphens: toc. Indeed, in this case, the content is added as the very first page. When you click on the line in the content, you go to the desired page of the document, page numbers are correct.
