If you replace a certain text with one containing multiple lines and you have certain formatting on the replaced element, the resulting lines lose the current formatting for all lines except the first one.

When converting an HTML file to DOCX file the HtmlFormatProvider imports inline style as file content and inserts it before the actual file content. Since converting HTML to PDF includes converting to DOCX first, as a middle step, this issue is also present in the converted PDF file.

Release R2 2022 SP1

Building Document Processing source code produces assemblies with the wrong VersionReleaseNumber. This leads to version 2022.1.<version_date> instead of 2022.2.<version_date>.

Workaround: Update VersionReleaseNumber to equal 2 in "...\Telerik_UI_For_WinForms_2022_2_510_DPL_source\DPL\Build\Imports\CommonConfig.targets"

Release R1 2022
The library allows up to 30 (instead of 31) characters of the sheet name.
Last Updated: 13 Dec 2021 11:28 by ADMIN

We found a small gap in Telerik's code, while defining name of Excel Sheet tab name (through Telerik Spreadsheet) --> using:

IWorksheetExporter CreateWorksheetExporter(string name);



When defining name of Excel sheet longer than 31 characters, Telerik code throws ArgumentException "Sheet name should be limited to 31 characters."

This is fine and correct - Excel sheet tab could be set UP TO 31 characters.

When using "shorter" name - like 30 characters, it works.

But when using exactly 31 characters, same Exception is thrown, which shouldn't be the case, as:
- Excel allows UP TO 31 charaters

- also you Exception message is clear that name should be limited TO 31 characters ;)

Dear Team,

when I create a pdf with your components (RadFixedDocument, RadFixedPage, FixedContentEditor) I cannot add a "german umlaut" in that report because then it cannot be viewed in your own pdfviewer- control (the exception is: Error loading document: Position is out of range).

I tried to solve this in "creating/ loading" arial.ttf as external font (even this is weird as idea), but this also did not work.

What is your solution for that?

I bought the Telerik components basically for PDF processing, this simply needs to work...

Many thanks for an urgent update on that!

Best regards
