The named ranges are not updated after rows or columns are inserted.

PDF/A-1a is with conformance level A (for "accessibility"), and must adhere to all of the requirements of the PDF Reference as modified by the ISO 19005 specification. 

It requires structural and semantic properties to be preserved. Level 1a uses “Tagged PDF” and Unicode character maps to preserve the document's logical structure and content text stream in natural reading order. 

The following features are used:
- Language specification
- Hierarchical document structure
- Tagged text spans and descriptive text for images and symbols
- Character mappings to Unicode

The purpose is to improve accessibility and make the content accessible for screen readers.

When exporting a specific document with a CIDFontType0 font (Korean TAWBUL+HGGGothicssiP80g or BPRSCV+HGGGothicssiP60g) the document is wrongly exported which leads to missing content.

Workaround:
After import you can change the font:

pdfDocument = provider.Import(memory);

FontBase malgunGothicFont;
FontsRepository.TryCreateFont(new FontFamily("Malgun Gothic"), out malgunGothicFont);

foreach (RadFixedPage page in pdfDocument.Pages)
{
	foreach (ContentElementBase element in page.Content)
	{
		TextFragment textFragment = element as TextFragment;
		if (textFragment != null && (textFragment.Font.Name == "TAWBUL+HGGGothicssiP80g" || textFragment.Font.Name == "BPRSCV+HGGGothicssiP60g"))
		{
			textFragment.Font = malgunGothicFont;
		}
	}
}

Importing html image with no source and then exporting it to pdf causes an exception, instead of omitting the faulty image.

Such images can be stripped using the following workaround:

List<ImageInline> images = this.document.EnumerateChildrenOfType<ImageInline>().ToList();

foreach (var image in images)
{
      if (image.Image.ImageSource == null)
      {
               image.Paragraph.Inlines.Remove(image);
      }
}

Implement nested mail merge and master-detail scenario.

The table is cut off when its width is larger than the default page width.

Workaround: 

var htmlProvider = new HtmlFormatProvider();
var document = htmlProvider.Import(File.ReadAllText(@"..\..\HTMLPage1.html"));

var tables = document.EnumerateChildrenOfType<Table>();
double maxWidth = document.Sections.FirstOrDefault().PageSize.Width;

foreach (var item in tables)
{
    if (item.PreferredWidth.Type == Telerik.Windows.Documents.Flow.Model.Styles.TableWidthUnitType.Fixed)
    {
        maxWidth = Math.Max(maxWidth, (item.PreferredWidth.Value + 100));
    }
}

foreach (var item in document.Sections)
{
    item.PageSize = new System.Windows.Size(maxWidth, item.PageSize.Height);
}

var pdfProvider = new PdfFormatProvider();
File.WriteAllBytes(@"..\..\result.pdf", pdfProvider.Export(document));

They are exported with the /EmbeddedFiles switch. This would allow adding external files to the PDF document.

Currently, a known limitation is:

• RadPdfProcessing currently supports only signing of a single signature field. Signing more than one signature field will result in invalidation of all signatures except the last one.

Please support signing multiple signature fields. We are heading into 2022 and it's more essential than ever to be able to sign multiple signature fields.

Currently, NotSupportedException is thrown when trying to import a document that uses Type 3 fonts.
Update: With Release R1 2021 the import of Type 3 fonts is already developed but the export is still not supported.

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 ;)
