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.

 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);
}

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.

 

This is the code for inserting the image: 

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

Missing/corrupted font characters during multithreaded PDF export.

The customers should have the ability to change the symbol used as a delimiter and the symbol used as a quote for a CSV document.

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.

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.

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

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

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.

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

RTF import loses the font applied once at paragraph/body level and falls back to a default font instead, when the  \fonttbl  uses flat, non-grouped font entries rather than individually braced  {\fN ...}  fonts.

Workaround: Re-save the document in MS Word.

 

PDF export places fixed-position images on the wrong page.

Missing table row content due to incorrect measurements after PDF export of a specific document.

PdfFormatProvider: Paragraph-style tab stops are not fully ignored during export, causing unexpected tab positions.

PDF export fails after HTML blocks containing empty or named anchors are imported and inserted into a RadFlowDocument through ReplaceText.

HTML importer creates hyperlink field markers for <a name="...">. During block replacement, cloned FieldCharacter instances lose FieldInfo, leaving orphan field markers. PDF exporter later dereferences FieldInfo and throws a NullReferenceException.

Internally, the WebClient class is used to load external resources. This class is not supported in Blazor and WordsProcessing should provide a mechanism for loading the resource.
