Table cell content is not displayed after PDF export if cell Preferred Width is too small.

Workaround: Make cell Size(Preferred Width) big enough for the contents to fit.

 

ArgumentException is thrown due to an element with an already existing parent while trying to split a table across pages.

Calculation of array formulas with large area references takes a lot of time.

When importing HTML content to a RadFlowDocument and exporting it to PDF format, the following error message occurs:

System.ArgumentException: 'The document element is associated with another parent. (Parameter 'item')'

In the current implementation, when the table and its cells don't define specific widths, they are automatically calculated according to the available space. This, however, might sometimes result in breaking whole words. The entirety of words should be preserved if that is possible in the concrete case.

Right alignment in a table does not work when converting from html to pdf

Importing the attached PDF throws InvalidCastException while parsing its structure tree. A /Layout attribute sets /BorderThickness to integer scalar 1. ISO 32000-1:2008 allows this value as a number or a four-entry array; a scalar applies to all four edges. The importer handles real values and arrays, but not PdfInt.

Setting PdfImportSettings.IgnoreMarkedContent to true currently skips marked-content containers but still imports the structure tree, so it does not avoid the exception.

Expected: Import integer and real scalar values as thickness for all four edges; preserve four-entry array values. When IgnoreMarkedContent is true, skip structure-tree import while still importing pages.

Calculation chain construction during import takes a lot of time for documents with formulas with large area references.

Missing/corrupted font characters during multithreaded PDF export.

InvalidCastException is thrown when importing a PDF with a CR-terminated comment in its /Info dictionary.

This missing functionality may be workaround by implementing and registering custom IPdfFilter implementation that decodes JPEG2000 images. The custom decoder may be registered with FiltersManager class and its implementation may be similar to RadPdfViewers JpxDecoder SDK example implementation:

- https://github.com/telerik/xaml-sdk/blob/master/PdfViewer/CustomDecoder/JpxDecoder.cs
- Use a custom JPXDecode filter with RadPdfViewer

Support for validating signature fields signed with signatures that are encoded in ETSI.CAdES.detached encoding should be added.

 Table with specified width in inches is not correctly exported when the size is set in inches (this is  done in the imported HTML) 

Workaround: set the table size in the code and remove the style.

foreach (Table table in document2.EnumerateChildrenOfType<Table>())
{
    table.LayoutType = TableLayoutType.FixedWidth;
    table.PreferredWidth = new TableWidthUnit(TableWidthUnitType.Fixed, 950);
}

This is the code for inserting the image: 

Workaround: Instead of setting the ImagePropertiesResolver, set the JpegImageConverter: 

Incorrect CID font resolution corrupts text after import-export.

Incorrect character spacing when importing CID fonts with the same BaseFont and different width tables.

Culture on generating computer: de-DE

• Format string: #.##0,00  -> Output correct: 1,234,567.89 (on US) and 1.234.567,89 (on German)
• Format string: #,##0.00  -> Output incorrect: 1,234,567.89 (on US) and 1.234.567,89 (on German)
• Format string: #.##0,0  -> Output incorrect: 1234567.8901 (on US) and 1234567,8901 (on German)
• Format string: #,##0.0  -> Output incorrect: 1,234,567.8 (on US) and 1.234.567,8 (on German)

The first string is an in-built string and is exported correctly. The other three strings are custom (not part of the in-built collection), are not converted to invariant culture and do not produce correct results when the file is opened in Excel.

Unexpected table content indentation during PDF export when cells lack explicit margins and do not inherit table-level margins.

Manual Workaround Before PDF Export:

Preserve direct cell overrides; materialize table-default padding only for cells with no local padding:

Using the PdfStreamSigner to set signature Properties like Name, Location, Reason, and ContactInfo is not respected after export.

Wrapped table cell text is incorrectly split by hyphens ("-").

This is a regression introduced in version 2026.3.826. Use an older version to avoid this issue.
