I want to be able to feed a table of data into the html importer, and have it figure out how many pages it needs to generate, but while doing that, have it add a page header to every page that the text from the table must always come under.

Is this possible or am I going to have to determine if the line i want to add for every html row can still fit on the page and if not, create a new page myself?

In a huge pdf, some part of table is placed previous page and the rest is placed next page. I need to keep a table together in one page. 

I only find a way might work (but didn't work) TableRow CanSplit property. To achieve this, I created wrapper table 1 row, 1 cell and set row CanSplit property to false. Then, added actual table to wrapper table cell. But this doesn't work.

Is there any way to keep them together?

Edit 1 : Using RadFlowDocument to create document and PdfFormatProvider to export.

create a fixedReadonly doc by importing readonly pdf
create a fixedFillable doc by importing fillable pdf
fixedReadonly.Merge(fixedFillable) 

pdfformatprovider.export(fixedReadonly) throws the error below.
but vice versa works.
but i need the fixedReadonly pages and then the fixedFillable pages in the exported pdf.

any idea?

Hi,

I'm developing a template creation application so users can create their own templates and such for mail merge purposes and I am wondering if there is any way to replace placeholders (for example "[order:id]") with merge fields using RadFlowDocumentEditor (replace text feature to be exact).

I already realized ReplaceText does not support FieldInfo and I know I can replace the placeholder with values from the database as well but I think there is probably a way to get actual templates from that.

Thanks in advance.

  RadFixedDocument doc = new PdfFormatProvider().Import(System.IO.File.OpenRead(localPdfFile));

I am trying to load a Adobe signed PDF document , but is throwing error as "The input data is not a complete block"

I have a PDF with a number of text fields that have a number format. I am updating them with calculated values: 

     If PDFdocument.AcroForm.FormFields.Contains(row.Item("XMLField").ToString()) Then
         field = PDFdocument.AcroForm.FormFields.Item(row.Item("XMLField").ToString())

         Select Case field.FieldType
               Case FormFieldType.TextBox
                         ModifyTextBox(CType(field, TextBoxField), OutText)
               Case FormFieldType.CheckBox
                         Try
                              ModifyCheckBox(CType(field, CheckBoxField), New String() {row.Item("OutText").ToString()})
                         Catch
                         End Try
         End Select
     End If

When this executes the number format is over written and I see 1222777.00 instead of 1,222,777.00.

Is there a way to either not lose the number format or reset the number format for the PDF Text field.? 

To clarify before the ModifyTextBox command the TextField is formatted as follows:

 After the ModifyTextBox command the format tab is changed to None:

 

When I run my application which converts RTF documents to HTML content, I get an HTML output without the footer and the header part. It seems that HtmlFormatProvider does not support exporting header and footers from RTF documents.

Is there any other way to do this conversion? or is this something that would be considered in the future?

using Telerik.Windows.Documents.Flow.FormatProviders.Html;
...

var htmlProvider = new HtmlFormatProvider();
html = htmlProvider.Export(rtfDocument);

 

 

Good morning,

I have a process which successfully generates a number of PDFs in a folder, and then compresses that folder into an unencrypted zip file.

I have used the code from a previous question:

https://www.telerik.com/forums/zip-content-of-a-folder-into-an-encrypted-zip-file

So my code is as follows:

public static void CreateZipFileFromDirectory(string sourceDirectoryName, string destinationArchiveFileName)

        {

            char[] directorySeparatorChar = new char[] { Path.DirectorySeparatorChar, Path.AltDirectorySeparatorChar };

 

            ZipArchiveMode archiveMode = System.IO.File.Exists(destinationArchiveFileName) ? ZipArchiveMode.Update : ZipArchiveMode.Create;

 

            if (!string.IsNullOrEmpty(sourceDirectoryName))

            {

                using FileStream archiveStream = System.IO.File.Open(destinationArchiveFileName, FileMode.OpenOrCreate);

                using ZipArchive archive = new ZipArchive(archiveStream, archiveMode, leaveOpen: false, entryNameEncoding: null);

                foreach (string fileName in Directory.GetFiles(sourceDirectoryName))

                {

                    using FileStream file = System.IO.File.OpenRead(fileName);

                    int length = fileName.Length - sourceDirectoryName.Length;

                    string entryName = fileName.Substring(sourceDirectoryName.Length, length);

                    entryName = entryName.TrimStart(directorySeparatorChar);

 

                    using ZipArchiveEntry entry = archive.CreateEntry(entryName);

                    using Stream entryStream = entry.Open();

                    file.CopyTo(entryStream);

                }

            }

        }

This creates the zip file and adds the first PDF successfully, but gives an error when trying to add the second PDF

"The process cannot access the file 'filename.zip' because it is being used by another process."

I have tried setting the leaveOpen parameter for the ZipArchive to true and to false but that gives me the same error.

Any ideas what I've missed?

I am doing images extraction from PDF. Having trouble to create image (in any format) from EncodedImageData (https://docs.telerik.com/devtools/document-processing/api/telerik.windows.documents.fixed.model.resources.encodedimagedata) structre.

Can someone post a sample code. I tired with this sample (https://www.telerik.com/forums/manipulate-image-elements) but without success.

My image have FlateDecode filter, "DeviceRGB" ColorSpace and 8 BitsPerComponent (see attached).

Environment is .NET Core.

I need to be able to take a pdf that is already created, and I need to search for sections of the pdf, insert and/or change existing text, and resave the pdf.

I saw the FixedContentEditor, but I only saw how to add, I didn't notice how to search for text or replace it?

Could you point me in the right direction?

Thank you!
