I want to use HtmlToPdf to convert an aspx page to pdf. The .aspx has around 80 controls (radiobuttonlists, checkboxlists, textboxes etc). and renders as a pdf of about 13 pages long.

The problem is the controls themselves only seem to render on the first page, after that I only see the text options for the radiobutton and checkboxlists and just the (visible) text from the textboxes. Am I asking too much of it? Or is there a setting somewhere that will help with this? I have the same problem with using ASPXToPDF.

My code is:

HttpResponse response = HttpContext.Current.Response;
response.Clear();
response.ClearHeaders();
response.ContentType = "application/pdf";
EO.Pdf.HtmlToPdf.ConvertUrl(Request.Url.AbsoluteUri, response.OutputStream);
response.End();

I also tried:
ASPXToPDF1.RenderAsPDF();

Hi,

Please check what version you are using. There was a bug like this in older version but it has since been fixed. If the newest build does not solve the problem for you, please try to isolate the problem into a test page and send the test page page to us. Once we have that, we will be happy to take a look.

Thanks!

I only downloaded it this week. Could it be because it is on a trial license?

Hi,

It shouldn't have anything to do with the trial license.

Thanks!

OK.

Here is a test page to illustrate the problem. My .aspx:

Thank you for checking. I've got it working now on our server, but for whatever reason it is still not playing ball on my development computer.

I have uninstalled eo.pdf and deleted the dll in the bin folder, checked that it can't see the dll, rebooted, re-downloaded the .exe from your site and reinstalled it, still no good. Ah well I can live with it.
