After upgrading the Telerik Document Processing libraries to version Q1 2025 the following error messages may occur:

* "The file or assembly cannot be loaded 'Telerik.Licensing.Runtime, Version=1.4.6.0, Culture=neutral, PublicKeyToken=token_here' or one of its dependencies. The system cannot find the specified file."

* "NU1101: Unable to find package Telerik.Licensing. No packages exist with this id in source(s): Telerik nuget. PackageSourceMapping is enabled, the following source(s) were not considered: Microsoft Visual Studio Offline Packages, nuget.org."

Is Telerik's NuGet server currently down or experiencing any issues? I'm unable to install packages from the Telerik feed, and I want to confirm if it's a known outage.

After recent update to 2025.2.520.462 I'm unable to extract file and save on disk. ExtractToFile() method is not longer here.
I've changed my usings from Telerik.WinControls.Zip to Telerik.Windows.Zip but I'm missing Telerik.Windows.Zip.Extensions.dll file.

What should I replace method ExtractToFile() with?

There is a code we use right now:

 

Byte[] bytes = File.ReadAllBytes(filePath);
using (MemoryStream zipStream = new MemoryStream(bytes))
using (ZipArchive archive = ZipArchive.Read(zipStream))
{
    foreach (ZipArchiveEntry entry in archive.Entries)
    {
        string extractedFilePath = Path.Combine(Path.GetTempPath(), entry.FullName);
        entry.ExtractToFile(extractedFilePath, true);
        thumbnail = AddGridFile(extractedFilePath);
        File.Delete(extractedFilePath);
    }
}

Folks,

For a new project I need to generate a dynamic multi page pdf and one of the mandatory requirements is that some kind of template (html, xml, word) is used for easier maintance purposes.

Is it correct that for the Telerik PDF processing Library the only way to define pdfs is directly in the c# code and not some kind of template?

Thank you

PdfProcessing - Developer Focused Examples - Telerik Document Processing

 

Hi,

we need to generate PDF/UA comform pdfs from scratch. Is that possible with Telerik PdfProcessing? I know that PDF/A works but we need PDF/UA specifically.

 

Thank you,

Valentin

We need to print a GridView and are implementing the code found in "GridView | Print and Print Preview" example in the WPF Desktop Examples 2024 Q4  app but are encountering two issues also present in the Telerik-provided example.

1) Changes made in Print Preview are not carried over when the Print button is pressed.  For example, if you change to Landscape/Legal in Print Preview, this will revert back to Portrait/Letter when Print is clicked.

2) Clicking Print on the Print Preview window shoves the Print Preview window to the background and if Cancel is clicked on the Print window, the user has to Alt-Tab through windows to find the Print Preview window to close it.

We need to set a spreadsheet font to Courier New in a WPF app using telerik.ui.for.wpf.60.xaml\2024.2.514.  As a first step, we do:

using System.Windows;
using Telerik.Documents.Common.Model;

namespace WpfApp4;

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        var fontFamily = new ThemableFontFamily("Courier New");
    }
}

Which is fine until we add a required cross-platform project referencing telerik.documents.core\2024.2.426

Then we get:

The type 'ThemableFontFamily' exists in both 'Telerik.Documents.Core, Version=2024.2.426.20, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' and 'Telerik.Windows.Documents.Core, Version=2024.2.426.60, Culture=neutral, PublicKeyToken=5803cfa389c90ce7'

Ambiguous reference.
Candidates are:
Telerik.Documents.Common.Model.ThemableColor
Telerik.Documents.Common.Model.ThemableColor

What is the proper fix for this to reference the version in the WPF app project?

Is it possible to add text to headers based on variables/database fields? I'm trying to loop through a table and use a field within the table as a page title, but all information I could find on this points to it being impossible in Telerik. Guidance would be much appreciated. 

Thanks

I am doing some document processing and want to use Telerik to display and edit. I need access to the paraId and textId elements of the docx "document" XML. I have explored the object model in the debugger and do not see these attributes. Are they available in the imported model?

Thanks.

 

Im using:
var xlsxProvider = new XlsxFormatProvider();
var pdfFormatProvider = new PdfFormatProvider();

byte[] docBytes = File.ReadAllBytes(path);
Workbook workbook = xlsxProvider.Import(docBytes, null);

byte[] resultBytes = pdfFormatProvider.Export(workbook, null);
File.WriteAllBytes(resultPath, resultBytes);

to conver xlsx file to pdf. In source xlsx file a have a Table and a formula '=SUBTOTAL(109, Table2[...]) that work in xlsx, but when i export it to PDF i need to have the calculated value, but instead im getting the string  '=SUBTOTAL(109, Table2[...]) . 

Is there a simple way to force calculation of all formulas in the sheet before exporting it to PDF?
