I got an 'System.InvalidOperationException' and message 'Cannot save a PDF document with no pages.'

[denghuichao]

I generate a PdfDocument with TheArtOfDev.HtmlRenderer.PdfSharp.PdfGenerator.GeneratePdf(html, PdfSharp.PageSize.Letter), and the html has contents, but the PdfDocument is empty and cause a 'System.InvalidOperationException' when i save the document by pdf.Save(memoryStream)

Hi guys, same issue for but only for first load of the application, any fix on this?

[mlaguayojr]

any update on this? I'm having the same error reading an html file

I was also getting this error, and I believe it was due to my Bootstrap column layout. Bootstrap puts display: flex; on elements with class="row", and HtmlRenderer doesn't seem to handle that well.

Here's a minimal reproduction; this code throws "System.InvalidOperationException: Cannot save a PDF document with no pages".

var htmlString = @"<div class=""row"">Hello, world!</div>";

var styleSheet = @".row { display: flex; }";

var pdf = PdfGenerator.GeneratePdf(
    html: htmlString,
    pageSize: PageSize.Letter,
    cssData: PdfGenerator.ParseStyleSheet(styleSheet));

pdf.Save("PdfSharp_FlexLayout.pdf");

I'm afraid I don't have a workaround at this time.

@benj2240 have you found a solution for this bug?

[benj2240]

@cfrancoluna I'm afraid not. I had to take my project in a different direction.
