I am trying to create and download a simple pdf using MVC but am having problems.

With Htmltopdf.converturl it just times out or loads comaniestopdf as an empty page

Quote:

[HttpPost]
public void CompaniesToPdf()
{
//no result, times out.
string url = "http://www.google.com";
PdfDocument doc = new PdfDocument();
HtmlToPdf.Options.NoScript = true;
HtmlToPdf.ConvertUrl(url, doc);
}


With HtmlToPdf.ConvertHtml it creates and downloads a pdf but it is completely empty.

Quote:
[HttpPost]
[RenderAsPDF]
public void CompaniesToPdf()
{
PdfDocument doc = new PdfDocument();
HtmlToPdf.ConvertHtml("test", doc);
}


Can you please help me sort out the syntax?

Hi,

I am not sure if I understand your intention correctly ---- your action method needs to return an ActionResult object, typically through View() method. MVCToPDF works by intercepting the result returned by your action method and then convert that result to PDF, which otherwise would be sent to the browser directly. So it won't work if your method returns void, and it wouldn't make sense for you to call HtmlToPdf.ConvertUrl/ConvertHtml in your action method either.

Thanks!

Thanks for this. So does that mean I can't use HtmlToPdf.ConvertUrl(url, doc) in an MVC project?

Of course you can. But that would not have anything to do with ASP.NET MVC and any of it's built-in logic.
