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);

of:

Telerik.Documents.SpreadsheetStreaming.IWorkbookExporter

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 ;)

public string AppendPdfList(string[] append)
{
           PdfFormatProvider provider = new PdfFormatProvider();
            RadFixedDocument targetDocument = new RadFixedDocument();
            provider.ImportSettings.DocumentUnhandledException += (o, args) => { args.Handled = true; };

            // Iterate through the files you would like to merge 
            foreach (string documentName in append)
            {
               RadFixedDocument sourceDocument = provider.Import(File.ReadAllBytes(documentName));
               targetDocument.Merge(sourceDocument);
            }
            TelerikPdfHelper.ClearDuplicatedFonts(targetDocument);

            OutputFilename = Path.GetTempFileName();
           File.WriteAllBytes(OutputFilename, provider.Export(targetDocument));
            return OutputFilename;
}

Results in System.NotImplementedException: 'The method or operation is not implemented.

Having issues when setting form text field that is rotated. The flatten method does not respect the alignment Middle/Right.

Also the field border does not get rotated.

See attached example.

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"
