How to load css file

[Jay]

Hi Team,

1.I want to load css file when import css file(bootstrap) and then export to a pdf file, but I find I lost all the css style, my code is below, did I miss something?

                    Telerik.Windows.Documents.Flow.FormatProviders.Html.HtmlFormatProvider htmlProvider
                        = new Telerik.Windows.Documents.Flow.FormatProviders.Html.HtmlFormatProvider();
                    // Create a document instance from the content. 
                    HtmlImportSettings importSettings = new HtmlImportSettings();
                    importSettings.LoadImageFromUri += (s, e) =>
                    {
                        // Load the data representing the resource  
                        SystemNet.WebClient webClient = new SystemNet.WebClient();
                        byte[] data = webClient.DownloadData(e.Uri);

                        // Pass the loaded data to the arguments 
                        string extension = SystemIO.Path.GetExtension(e.Uri).Substring(1); // Get the extension without the dot 
                        e.SetImageInfo(data, extension);
                    };
                    importSettings.LoadStyleSheetFromUri += (s, e) =>
                    {
                        string styles = fs.File.ReadAllText(Server.MapPath("~") + e.Uri);
                        e.SetStyleSheetContent(styles);
                    };
                    htmlProvider.ImportSettings = importSettings;
                    htmlProvider.ImportSettings.DefaultStyleSheet = string.Empty;
                    RadFlowDocument document = htmlProvider.Import(htmlStr);
                    Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider pdfProvider
                        = new Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider();
                    // Export the document. The different overloads enables you to export to a byte[] or to a Stream. 
                    byte[] pdfBytes = pdfProvider.Export(document);

2. Can I use the code like below to set the default style to empty?

                    htmlProvider.ImportSettings.DefaultStyleSheet = string.Empty;

Hi Jay,

As far as I can see, your approach seems correct. Maybe there is some unsupported CSS construct, or there is some other issue that is specific to the document. I noticed that you sent the same inquiry through our support ticketing system. Would it be possible for you to send us the faulty HTML and CSS files and I will test the scenario on my side?

As for the DefaultStylesheet, you should be able to clear the defaults by setting it to empty.
