The value of the TextBoxField is not visible until the field is clicked.
Workaround: Force content update:
foreach (var widget in textBoxField.Widgets)
{
widget.RecalculateContent();
}If the update still doesn't fix the issue, change the font prior to setting the value of the field:
foreach (var widget in textBoxField.Widgets)
{
widget.TextProperties.Font = FontsRepository.Helvetica;
}RESOLVED: The issue is dismissed. The actual reason for the results is that FontsProvider implementation is missing. For accurately displaying the text the fonts used in the document need to be resolved correctly.
RadPdfProcessing currently supports interactive forms whose data is defined directly in the document. Add support for interactive forms based on the Adobe XML Forms Architecture (XFA). The entry is defined inside the interactive forms dictionary and refers to an XML stream containing the information of the form. More information is available on page 722 from Pdf Reference, version 1.7.
Updates:
- November 2024
From PDF 2.0 (ISO 32000-2) the XFA forms are depreciated. For this reason, we are changing our plans and declining this item, but we will provide import-export support to avoid losing existing XFA content. Please, subscribe to the following public item: PdfProcessing: Add support for XFA fields import-export.
For the Telerik Spreadsheet control, XlsxFormatProvider.Export() API is used for saving the .xlsx file manually without the UI command(Save As dialog) invocation. This API is currently returning a byte stream.
The requirement is that the API should also intimate the user whether the export is successful or not by returning a boolean value.
Note: I think we can implement this requirement at the base level which is for the BinaryFormatProviderBase class or atleast at the FormatProviderBase class.
Typically, it is the text to be displayed for the annotation or, if the annotation does not display text, an alternate description of the annotation’s contents in human-readable form.
This item will be closed as its subject is too broad. Please refer to the information below for the individual markup annotations.
As of now, the currently supported markup annotations are:
Text
Line
Highlight
Underline
Squiggly
StrikeOut
Stamp
The unsupported annotations and their respective feedback items are:
FreeText
Square
Circle
Polygon
PolyLine
Caret
Ink
FileAttachment
Sound
When an import of the attached PDF file is executed, the result is a file with vertically rotated images, as well as enlarged and distorted. This is part of the code executed in the final application. Do you have any idea why this is happening? Is there any suggested solution?
As a result of the imported file, other processes are executed, such as creating bookmarks and page numbering, but the result is incorrect when presenting the rotated images.
Please find attached a code snippet and the input and generated output file.
Thank you.

I am using .net 7. I originally hit it with Telerik.UI.for.Wpf.70.Xaml.2023.3.1114. I updated to Telerik.UI.for.Wpf.70.Xaml.2024.1.423 to see if it was fixed but it still appears to happen.
I have attached a sample program which shows the behavior. Original.xlsm was created in Excel and has an image embedded in cell A1. Call ImportWorkbook with the path to the original file. Then export that workbook (unchanged) to the destination file.
Workbook workbook = ImportWorkbook( originalFileName ); ExportWorkbook( workbook, destinationFileName );
private Workbook ImportWorkbook( string fileName )
{
Telerik.Windows.Documents.Spreadsheet.Model.Workbook workbook;
IWorkbookFormatProvider formatProvider = new Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.Xlsm.XlsmFormatProvider();
using( Stream input = new FileStream( fileName, FileMode.Open ) )
{
workbook = formatProvider.Import( input );
}
return workbook;
}
private void ExportWorkbook( Workbook workbook, string fileName )
{
Telerik.Windows.Documents.Spreadsheet.FormatProviders.IWorkbookFormatProvider formatProvider = new Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.Xlsm.XlsmFormatProvider();
using( Stream output = new FileStream( fileName, FileMode.Create ) )
{
formatProvider.Export( workbook, output );

I'm currently working with the large PDFs. I'm able to process PDFs up to 2.1 GB easily without any error using Telerik Document Processing. However, if I take a larger PDF (e.g. 2.8 GB), PdfFormatProvider.Import throws an IOException with the next message: "The parameter is incorrect. : {path}".
I'm using FileStream to provide a sample for the Import method.
I've checked it with the different samples, all have the same behavior. So, I guess, it will work for any PDF larger than 2.1 GB.
Steps to reproduce:
1.Create a zip archive for a txt file with password protection
2. Try updating the protected file and insert a new text line for example.
As a result, an error occurs: System.ObjectDisposedException: 'Cannot access a closed Stream.'

In WorksheetPageSetup, you can only get the PageSize, but not set it. The only way is through setting a PaperType.
This is because in Telerik.Windows.Documents.Spreadsheet.Model.Printing.SheetPageSetupBase, the only way to set the pageSize property is by setting a PaperType, then it uses PaperTypeConverter.ToSize(PaperType) to convert it to the pageSize. I cannot see any other way to set this to a custom size set by the user.
Please allow custom page sizing by adding a setter for the PageSize if possible. Thank you!
WorksheetPageSetup pageSetup = worksheet.WorksheetPageSetup;
Size pageSize = new Size(50, 80)
pageSetup.PageSize = pageSize; // produces cs0200
pageSetup.PageSize.Width = pageSize.Width; // produces cs1612
pageSetup.PageSize.Height = pageSize.Height; // produces cs1612
Hello, I had many problems with version 2023.1.117, latest stable 2023.2.606 is unusable also due to issue with scanned documents etc, so I tried 2020.2.703-hotfix, but I am getting other set of issues.
Unfortunately I cannot share the documents, since they are confidential.
With some documents I am getting this error:

I'm trying to use the PdfFormatProvider to import a pdf. I've tried to import multiple different pdfs with the code below, but they all throw an exception with "System.InvalidOperationException: 'Import not supported.'" and no other info. Is this a bug or am I not calling the correct method to import a pdf?
var providerPDF = new Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider(); providerPDF.Import(File.ReadAllBytes(@"D:\TestDocs\TestImage.pdf"));
Hello,
I'm using Telerik Documents Processing 2023.1.410
With WordsProcessing, if I add a table in a footer it will automatically add a space after the table
Here an example, my table is the same size as my image in background and I removed all margin of the section:
Here the code:
Footer footer = section.Footers.Add(HeaderFooterType.Default)
section.PageMargins = new Padding(0,96,96,0);
section.FooterBottomMargin = 0;
Table table = footer.Blocks.AddTable();
TableRow row = table.Rows.AddTableRow();
TableCell cell = row.Cells.AddTableCell();
Paragraph paragraph = cell.Blocks.AddParagraph();
paragraph.Inlines.AddRun("Something");
I didn't any properties to manage spaces around a Table like in Paragraph.
It can be reproduced without the image
Work around:
If I add a new paragraph at the end and remove all spaces of this paragraph then it works
Here the code added:
paragraph = footer.Blocks.AddParagraph();
paragraph.Spacing.SpacingAfter = 0;
paragraph.Spacing.SpacingBefore = 0;
paragraph.Spacing.LineSpacing = 0;

Hervouet Thomas
Hi
is there possible Telerik RadSpreadProcessing able to print repeat column on every printed page?
When importing an XLSX that has "Date" number-formatted cells, and those cells have the 5-digit representation of th edate, XslxFormatProvider.Import(bytes) will throw a KeyNotFoundException. The exception message is "The given key '58' was not present in the dictionary" for the particular case we're looking at.
Unfortunately, we cannot provide the file itself, as it has PHI in it. And, when we open it in Excel and resave it, Excel will automatically convert the 5-digit representation to a normal date. This new file will import just fine. However, we're trying to cut out that intermediate step.
Pertinent portion of the stack trace:

Export should take into account JavaScript and produce PDF similar to the original page.
