Issue: While converting HTML to PDF the Bootstrap CSS classes are not reflected

Hello Support,

We have using Aspose.pdf version as 11.1.1.
And trying to convert HTML to PDF. Our HTML contains some Bootstrap CSS classes.
But after conversion to PDF, it does not reflect in it.

Following code we have written:

//Load HTML string
Document doc = new Document(new
MemoryStream(System.Text.Encoding.UTF8.GetBytes(html)), htmlLoadOptions);

//Save PDF file
doc.Save(@“C:\TestPDf\outputoutput.pdf”);
//** end

html = It’s a Inner HTML of .aspx page and css reference is given as
http://localhost:50333/Website/Secure/JScriptFrameWork/KendoUI/styles/kendo.bootstrap.min.css

Please suggest.
Thank you.

Hi Ajay,


Thanks for your inquiry. Please note when you need convert a HTML that is using some external resources (CSS/Images/Fonts) then you need to pass resources path to HtmlLoadOptions() as parameter.

Please check following documentation links for details, these will help you to accomplish the task. However if the issue persist then please share your sample HTML and resource files, so we will check and guide you accordingly.


We are sorry for the inconvenience caused.

Best Regards,

Hello Support Team,

Thanks for the response.

I have tried the both option.(Convert Html to PDF and Convert Web page to PDF).

But none of them worked for me.

While I trying with the 2nd option i.e. Webpage to PDF in that, even I logged in and specify web request URL as follows,:

WebRequest request = WebRequest.Create(“http://localhost:50333/Website/ABC.aspx”);

the resultant PDF is generated for Login page not for the ABC.aspx page.

Please find the following code sample.

1] ** ABC.aspx

2] On code behind side .cs

srtring html ==  /* Inner HTML of ABC.aspx page .*/
HtmlLoadOptions htmlLoadOptions = new HtmlLoadOptions("http://localhost:50333/Website/Themes");
//Load HTML string 
Document doc = new Document(new MemoryStream(System.Text.Encoding.UTF8.GetBytes(html)), htmlLoadOptions);
doc.Save(@"C:\TestPDf\outputoutput.pdf")

Please suggest. Thank you.
