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."

RadFlowDocument document = provider.Import(htmlContent, new TimeSpan(0, 0, 0, 30));

I have a PDF that's supposed to use bootstrap styles, and I'm having trouble applying them.  I have three divs that need to be in-line but they keep end up on their own line instead.  They are an image, then a title, then another image.  All need to be on one line.  But bootstrap, flex, whatever I throw at it, they keep going on their own lines instead, like block elements.

I want:  image/title/image

I get:

image
title
image

Here's the cshtml:

This isn't the whole document, just the relevant part I'm struggling with.  Linking bootstrap directly didn't work (and seemed like a bad idea anyways due to its size) so I just started copying in the relevant classes into the style tag.  The .row class alone should be sufficient to make the three divs (the two images and the title) all inline in one line, but it seems to have no effect in the PDF.  I also tried making one of the divs a flex container by giving it display:flex and again, no effect.  If I grab the HTML string from the debugger, the moment before it is fed into this: RadFlowDocument document = provider.Import(htmlContent, new TimeSpan(0, 0, 0, 30)); and I take that html and save it as an html document and open it in my browser, the classes work appropriately, the image/title/image display inline as desired.  So I know the mark up and the CSS are functional, but I don't get why it doesn't work with the conversion to PDF.

I'm also aware that putting flex in one of the divs inside a .row div is redundant but I was trying to figure out what wasn't working.

Hello,

I'm trying to rewrite a PDF-generator function that creates a PDF from HTML (which is the result of an XSLT+xml transform) using another HTML to PDF library to a new function that uses the Telerik methods. That works Ok, but there are 2 things I can't figure out how to do (if even possible) :

- The HTML content consists of a table with uneven row heights, depending on the content. Some rows contain images, some don't. So, I can't determine beforehand which row needs to start on a new page. Currently, I use page-break-inside: avoid on the rows, and that works with the other library, but not with the Telerik methods. Some rows are split over two pages. How can I prevent an element from breaking up over two pages?

- With the current library, I'm able to provide a separate PDF file that is used as a background for every rendered page. That PDF is a single-page PDF with the 'corporate stationery' (don't know how that's called ;-), so the resulting PDF contains multiple pages with the HTML output in the company style. Is something like that possible with the Telerik methods?  I know how to draw a small HTML snippet on a single PDF page, but I can't figure out how to convert HTML to PDF with this background on every page.

Any help is appreciated.

Regards,
Kees

I am looking at this example.  Is it possible to format the text using HTML tags?

void ProcessTextBox(TextBoxField textBoxField, string textboxValue)
    {
        textBoxField.Value = textboxValue;
    }

Hello,

I just upgraded telerik, and i have troubles referencing  Workbook / Worksheet / etc...

Is the documentation up to date ?

In the documentation, namespace for Workbook is still Telerik.Windows.Documents.Spreadsheet.Model. But it doesnt exist anymore : 

I am using 11.1.0 :

I've obtained a x509 signing certificate and able to use it with Telerik PDF processing to generate a signed PDF. The problem is that none of the signatures are valid because of the time stamp!

There doesn't appear to be any way to insert a TSA timestamp with the signing flow.

How can I fix this, the Telerik signatures are useless otherwise.

Thanks!

I'm using SpreadProcessing in conjunction with a Blazor TelerikSpreadsheet component and I've found that when I copy a cell from any Excel file and paste that into any cell in the TelerikSpreadsheet and then subsequently call XlsxFormatProvider.Import(), it throws an exception with the following message:

Not supported from value: start

I've attached a sample project to demonstrate the issue.

How can I successfully paste from Excel and then call XlsxFormatProvider.Import()?
