I'm adding PieCharts to my excel and I couldn't find a way to add Data labels. Is there way to add Data labels to the Pie? And also can we add point explosion to the Pie?

Hi,

I need help to setup page orientation to landscape due to size of the contents in cells. 

Here is my code.

public RadFlowDocument CreateDocument(ref RadFlowDocument document, List<LetterGenerateData> initltr, string pathlogo)
{
    RadFlowDocumentEditor editor = new RadFlowDocumentEditor(document);
    Stream stream = File.Open(pathlogo, FileMode.Open);

    using (stream)
    {
        Telerik.Windows.Documents.Media.ImageSource image = new Telerik.Windows.Documents.Media.ImageSource(stream, "png");
        editor.InsertImageInline(stream, "png", new System.Windows.Size(168, 48));
    }

    var codeFont = new ThemableFontFamily(new System.Windows.Media.FontFamily("Arial"));
    editor.CharacterFormatting.FontFamily.LocalValue = codeFont;
    editor.CharacterFormatting.FontWeight.LocalValue = FontWeights.Bold;
    editor.CharacterFormatting.FontSize.LocalValue = 12.0;
    editor.InsertText("Statement");
    document.StyleRepository.AddBuiltInStyle(BuiltInStyleNames.TableGridStyleId);
    editor.TableFormatting.StyleId = BuiltInStyleNames.TableGridStyleId;

    var table = editor.InsertTable();
    var headerrow = table.Rows.AddTableRow();
    headerrow.RepeatOnEveryPage = true;
    var hcell1 = headerrow.Cells.AddTableCell();

    hcell1.Blocks.AddParagraph().Inlines.AddRun("Name").FontWeight = FontWeights.Bold;
    var hcell2 = headerrow.Cells.AddTableCell();
    hcell2.Blocks.AddParagraph().Inlines.AddRun("Profession").FontWeight = FontWeights.Bold;
    var hcell3 = headerrow.Cells.AddTableCell();
    hcell3.Blocks.AddParagraph().Inlines.AddRun("Age").FontWeight = FontWeights.Bold;
   
    foreach (var item in initltr)
    {
        var row = table.Rows.AddTableRow();
        var cell1 = row.Cells.AddTableCell();
        var cell2 = row.Cells.AddTableCell();
        var cell3 = row.Cells.AddTableCell();
        cell1.Blocks.AddParagraph().Inlines.AddRun(item.Name).FontSize = 9;
        cell2.Blocks.AddParagraph().Inlines.AddRun(item.Profession).FontSize = 9;
        cell3.Blocks.AddParagraph().Inlines.AddRun(item.Age).FontSize = 9;
    }

    return document;
}

Much appreciated.

 

Hi

I am generating a PDF from a html file using HtmlFormatProvider, RadFlowDocument and PdfFormatProvider.

The generated PDF contains some large tables that is not rendered correctly.

This can be solved if I can set the html page witdth somehow.  Is it possible?

 

I have a Template pdf (With company logo as letter head). I want to use this pdf as the first page when I'm creating my pdf. 

Here's my sample code. It creates the letter head in the first page and the rest of the content in a new page.

 

PdfFormatProvider provider = new PdfFormatProvider();
RadFixedDocument document = provider.Import(File.ReadAllBytes(InputFileName));

            using (RadFixedDocumentEditor editor = new RadFixedDocumentEditor(document))
            {

                editor.ParagraphProperties.SpacingBefore = 10;
                editor.ParagraphProperties.HorizontalAlignment = Telerik.Windows.Documents.Fixed.Model.Editing.Flow.HorizontalAlignment.Center;
                editor.InsertParagraph();
                editor.CharacterProperties.FontSize = 40;
                editor.CharacterProperties.Font = boldItalicFont;
                editor.InsertRun("Summary of Proxy Votes");

 

I'm having this issue with some digital signed pdfs. 

Here is the code that gets the exception:

var signatureFields = document.AcroForm.FormFields.Where(field => field.FieldType == FormFieldType.Signature).ToList();
            if (signatureFields.IsNotNullOrEmpty())
            {
                foreach (var signatureField in signatureFields)
                {
                    var field = (SignatureField)signatureField;

                    if (field != null && field.Signature != null)
                    {
                        var test = field.Signature.Validate(); - this is the line where I get the exceptions!

 

The method Validate() called without the properties parameter throws exception in 2 cases:

1st - using pdf signed with specialized software

Message: "No signature validation handler was found for the subfilter: ETSI.CAdES.detached

and the StackTrace: at Telerik.Windows.Documents.Fixed.Model.DigitalSignatures.Signature.Validate(SignatureValidationProperties validationProperties)\r\n   at Telerik.Windows.Documents.Fixed.Model.DigitalSignatures.Signature.Validate()\r\n   at... (there goes the path in my project)

2nd - using pdf signed with the same digital signature by Adobe Acrobat Reader

Message "ASN1 bad tag value met.\r\n"

and the StackTrace: at System.Security.Cryptography.Pkcs.SignedCms.OpenToDecode(Byte[] encodedMessage, ContentInfo contentInfo, Boolean detached)\r\n   at System.Security.Cryptography.Pkcs.SignedCms.Decode(Byte[] encodedMessage)\r\n   at Telerik.Windows.Documents.Fixed.Model.DigitalSignatures.Pkcs7Detached.ValidateOverride(SignatureDataProperties dataProperties, SignatureValidationProperties validationProperties)\r\n   at Telerik.Windows.Documents.Fixed.Model.DigitalSignatures.SignatureValidationHandlerBase.Validate(SignatureDataProperties dataProperties, SignatureValidationProperties validationProperties)\r\n   at Telerik.Windows.Documents.Fixed.Model.DigitalSignatures.Signature.Validate(SignatureValidationProperties validationProperties)\r\n   at Telerik.Windows.Documents.Fixed.Model.DigitalSignatures.Signature.Validate()\r\n   at... (there goes the path in my project)

I'll be glad if you can tell me where the problem is and what can I do to fix it. 

I want to be clear, there are just some correctly signed pdfs that cannot pass this validation. Most of them can but I'm afraid that I am missing something, as one of the non-passing digital signatures is new.

 

Hello

I would like to create PDF file, as container for images, (the source of the images is scanner).
I order to make small file size, I'm converting the images from BMP to JPEG and then do the export to PDF file,
but the output file size is huge.
I'm following this example.


1. How can i control the PDF file size?
2. Is the PDF export saves JPEG  image as is or decode and then save it?


My Code:

​

01.void f(List<Bitmap> Images)

02.{

03.  DateTime now = DateTime.Now;

04.  string name = "scan-" + now.ToString("yyyyMMdd") + "-" + now.ToString("HHmmss") + "_3" + ".pdf";

05.             

06.  using (FileStream FileStream = new FileStream(@"c:\Users\avicode\Desktop\tmp\" + name,FileMode.Create))

07.  using (MemoryStream ms = new MemoryStream())

08.             

09.  if (Images.Count >= 1)

10.  {

11.    RadDocument document = new RadDocument();

12.    for (int i = 0; i < Images.Count; i++)

13.    {

14.      System.Drawing.Image oBmpImage = (System.Drawing.Image)Images[Images.Count - 1];

15.      oBmpImage.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);

16.      Telerik.Windows.Documents.Model.Section section = new Telerik.Windows.Documents.Model.Section();

17.      Telerik.Windows.Documents.Model.Paragraph paragraph = new Telerik.Windows.Documents.Model.Paragraph();

18. 

19.      ImageInline image = new ImageInline(ms);

20.      paragraph.Inlines.Add(image);

21.      section.Blocks.Add(paragraph);

22.      document.Sections.Add(section);

23. 

24.    }

25.    PdfFormatProvider oPdf = new PdfFormatProvider();

26.    oPdf.Export(document,FileStream);

27.    }

28.}

I need to know how to email a digitally signed PDF document from a user input webform.

I want to set table line style like this attachment. How Can I set this table line style?

Borders I am creating with RadFlowDocumentEditor are not displayed in Radrichtextbox, to demonstrate here is my test code, I am using Telerik UI for WPF R2 2019.

Attached is the file, also how it is displayed in Word and the how it is displayed in the RadRichTextBox inside my application.
