Hello Ranjith,

RadRichTextBox exposes several format providers that allow you to convert a document from one type to another. In your case you can import the HTML with HtmlFormatProvider and export it to PDF with the PdfFormatProvider class. More information is available in the Import/Export help article.

Once you've generated the desired PDF you can use the RadPdfViewer component which is part of the Telerik UI for WPF suite to show it. I suggest you check the documentation of the control as well as its SDK examples: RadPdfViewer Overview, Showing a File, SDK Samples Browser.

I hope this is helpful.

Hi,

Please find the below code,while opening pdf from html file.

​ string html = File.ReadAllText(ViewDetails.html);
string pdfPath = strDestinationPath + strSessionID + _Params.CustomizeID +"Configuration Details.pdf";
HtmlFormatProvider provider = new HtmlFormatProvider();
RadDocument document = provider.Import(html);
PdfFormatProvider pdf = new PdfFormatProvider();
var bytes= pdf.Export(document);
if (File.Exists(pdfPath))
{
File.SetAttributes(pdfPath, FileAttributes.Normal);
}

var fs = new FileStream(pdfPath, FileMode.Create);
fs.Write(bytes, 0, bytes.Length);
fs.Close();
Process.Start(pdfPath);

It is displaying empty PDF file.But "ViewDetails.html" having data.If i open in browser it will display the datails.

How can i display Html data into PDF.

Hello Ranjith,

I am not sure what might be causing this result on your end. Could you confirm this is the behavior with all HTML documents or does the issue depend on the HTML content? Please also try the behavior of the attached application, the source HTML it uses is located in the \ExportPdfDemo\ExportPdfDemo\bin\Debug\SampleData folder.

I'm looking forward to your reply.

Hi,

When i add this code

 string html = File.ReadAllText(@"C:\Users\ranjith.p01\Downloads\ExportPdfDemo\bin\Debug\SampleData\test.html");
            string pdfPath = "SampleData\\Configuration Details.pdf";

            HtmlFormatProvider provider = new HtmlFormatProvider();
            RadDocument document = provider.Import(html);
            PdfFormatProvider pdf = new PdfFormatProvider();

            var bytes = pdf.Export(document);
            if (File.Exists(pdfPath))
            {
                File.SetAttributes(pdfPath, FileAttributes.Normal);
            }

            var fs = new FileStream(pdfPath, FileMode.Create);
            fs.Write(bytes, 0, bytes.Length);
            fs.Close();
            Process.Start(pdfPath);

I am getting Error:The type initializer for 'Telerik.Windows.Documents.Model.RadDocument' threw an exception.

near this line: RadDocument document = provider.Import(html);

Please give me reply ASAP.

Hello Ranjith,

Could you provide us with the source document that you are having troubles exporting? I'm afraid that I am unable to comment on what might be causing this without investigating the HTML first. 

Note that the public forums do not allow attachments. You can open a support ticket and attach the file there.

Looking forward to hearing from you.

Hello,

For anyone else that might encounter this topic, the issue was caused due to specific content in the HTML that prevents the document from being imported in the control. The public item for this can be found at Documents with STYLE tag are not imported properly.

How to remove the space between line to line and How to reduce font size in PDF document.

            RadDocument document = provider.Import(html);

Hello Runjith,

Without the actual HTML, we would be guessing what is causing the empty space in your document. You could try showing the document in RadRichTextBox prior the export and enabling the formatting symbols to see whether they are additional paragraphs in that place. Alternatively, send us your HTML document so that we can look into the cause.

Regarding the font size, you can reduce it by selecting the desired content and calling the ChangeFontSize() method of RadRichTextBox or RadDocumentEditor. This article provides more details on document selection.

As to the scale factor when showing a document, such settings are not supported by the PdfFormatProvider so this is not information that is exported in the PDF file. The scale factor with which a document is loaded depends on the software that shows the PDF.
