I’m working on a project at the moment that needs to generate a PDF document from data on the SQL Server. The following steps illustrates the approach I’m using but in this article I want to focus on the HTML to PDF conversion using the C# port of iText, iTextSharp.
- Select the required data into a .net DataSet
- Create a new XmlDataDocument(DataSet) so that we have our data in XML
- Create a new XSLT converter using XslCompiledTransform, load the XSLT file, then transform the XML to the output HTML we need
So the HTML I have is structured correctly and links to images that are required to be included in the PDF output. In order to generate the PDF i went searching for a free PDF API and iTextSharp seems to be the commonly used from what I could tell. I’ve had a quick read through their API documentation and put together a quick example of how to generate a PDF from an existing HTML file (so this doesn’t use the iTextSharp elements). I hope this is useful (click on the image to enlarge):
To invoke the method, you simple pass in the source HTML file location (use MapPath() if on a web server) and where you want your output PDF to be created. Simples.
