I have problem with converting HTML to PDF with c# coding. Namely, I go through next steps:

1) creating HtmlFormatProvider

2) registering event LoadStyleSheetFromUri

3) importing Stream with HTML content. Content contains reference to bootstrap.css, Bootstrap v4.3.1 (https://getbootstrap.com/)

4) creating PdfFormatProvider

5) exporting to pdf.

Complete code is following:

       public async static Task<InputSignDocument> CreateDemoDocument(string wwwPath, string fileName, string extension, string recipientName, string recipientEmail, Func<Task<Stream>> getPdfStream)
        {
            var result = new InputSignDocument()
            { 
                FileName = fileName,
                FileExtension = extension,
            };

            Stream inpuContent = await getPdfStream(); // here is reading html into stream
            var htmlProvider = new HtmlFormatProvider();

            HtmlImportSettings importSettings = new HtmlImportSettings();

            importSettings.LoadStyleSheetFromUri += (s, e) =>
            {
                  string styles = File.ReadAllText($"{wwwPath}\\{e.Uri}");

                e.SetStyleSheetContent(styles);
            };
            importSettings.DefaultStyleSheet = "body {white-space: normal;}";
            htmlProvider.ImportSettings = importSettings;

            RadFlowDocument doc;
           using (StreamReader reader = new StreamReader(inpuContent))
            {
                string htmlText = reader.ReadToEnd();
                doc = htmlProvider.Import(htmlText);
            }

            var pdfProvider = new Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider();

            PdfExportSettings exportSettings = new PdfExportSettings()
            {

            };
            pdfProvider.ExportSettings = exportSettings;

            result.FileContent = new MemoryStream();
            pdfProvider.Export(doc, result.FileContent);

            return result;
        }

PDF is created however no bootstrap classes are apllied.

In debug session I look in variable (string styles) in event, css file was read properly.

HTML contains two references:

<link rel="stylesheet" href="/lib/bootstrap/dist/css/bootstrap.css" />
<link rel="stylesheet" href="/css/site.css" />
From event I see that both files are exported.

In HTML, namely, in razor view are used bootstrap classes: container, col-lg-6, col-md-6, col-sm-6, row.

rhey are applied this way:

<div class="container">
    <div class="row">
        <div class="col-lg-6 col-md-6 col-sm-6">
            <div class="row">
                <div class="col-lg-4 col-md-4 col-sm-4">
                    <label>Werknemer</label>
                    <div>
                        /fnm1/
                    </div>
                </div>

                <label></label>
                <div class="col-lg-4 col-md-4 col-sm-4">
                    <label>Handtekening</label>
                    <div>
                        /sn1/
                        <hr />
                    </div>
                </div>

                <div class="col-lg-4 col-md-4 col-sm-4 docusign-basetab">
                    <label>Aangetekend op</label>
                    <div>
                        /ds1/
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>

It seems that this part css is not applied in PDF File.

What I am missing?

When I run the view from controller it shows me this:

And in pdf it looks like this:

I am trying to convert a HTML body to a PDF using HtmlFormatProvider and PdfFormatProvider. 

It works well when I try to create a pdf with "normal" characters, but when I use characters like "åäö" the characters is either missing or replaced with other character. 

I have seen a similiar issue that recommended to load in the fonts, but that did not solve the issue for me. 

I have added the code in a zip as an attchment to this issue. 

Thanks in advance.

public static void ConvertWordtopdf(string input, string output)
        {
            var docxProvider = new Telerik.Windows.Documents.Flow.FormatProviders.Docx.DocxFormatProvider();
            var pdfProvider = new Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider();


            try
            {
                //var docxBytes = File.ReadAllBytes(input);
                var docxBytes = System.IO.File.OpenRead(input);
                RadFlowDocument docx = docxProvider.Import(docxBytes);

                var pdfBytes = pdfProvider.Export(docx);
                File.WriteAllBytes(output, pdfBytes);

                docxBytes.Dispose();
                
            }
            catch (Exception ex)
            {
                ;
            }
        }

Dear Telerik Developers,

Since the Xamarin Platform realize the Rich Text Editor by a webview control, I have to convert my Rtf files into html format before loading.

According to the Html Conversion document, headings ( h1 - h6 )  styles have nothing to do with the Outline Level,  and would be lost when exporting to other formats.

While in my scenario, the outline data of original Rtf document should be kept while converting back from html format to Rtf code.

My suggestion is adding a "EnableOutlineToHeadingsConversion" option to both HtmlImportSettings and  HtmlExportSettings classes, so that we can decide if the Outline level data should be converted into corresponding Headings Style ( for example, Outline Level 1 -> h1 ) and vice versa.

HtmlFormatProvider provider = new HtmlFormatProvider(); 
HtmlExportSettings exportSettings = new HtmlExportSettings(); 
  
exportSettings.BordersMinimalThickness = 1; 
exportSettings.DocumentExportLevel = DocumentExportLevel.Fragment; 
exportSettings.IndentDocument = true; 
exportSettings.EnableOutlineToHeadingsConversion = true;
 
provider.ExportSettings = exportSettings; 

I sincerely hope this could be taken into Telerik's developing consideration.

Regards,

Thank you very much. 

I'm trying to convert a DataTable to a spreadsheet.

According to the documentation:

To use the DataTableFormatProvider you need to reference the Telerik.Windows.Documents.Spreadsheet assembly.

After adding a reference to this assembly, Visual Studio still does not recognize it. Where can I find the DataTableFormatProvider?

Thanks,

Tim

I am using versions 2021.1.322.40 of Core.dll, Fixed.dll and Zip.dll and when exporting a RadFixedDocument to pdf it tells me that the value of RadFixedDocument cannot be converted to RadFlowDocument

What can I do to solve this problem?

I am using this :

Hi

Using Telerik.Windows.Documents.Spreadsheet.Model.Workbook class, it seems there is no VLOOKUP function, although there is a LOOKUP function which works almost the same way. The lack of VLOOKUP specifically impacts my ability to load existing Excel documents. Is there a way to add a VLOOKUP function to the SpreadProcessing engine?

Thanks,

Guy

We are migrating to telerik but our main issue is that XlsFormatProvider keep gaving OutOfMemoryException when importing files  either on stream or bytes, and this where easily imported on same machines using ASPOSE dlls

is there a way to have this sorted out another library i should use or different class?
