Import archives without an end-of-central-directory record.

Although it is mandatory according to the specification, it seems like other applications don't require this record. Trying to open such an archive with RadZipLibrary currently throws an InvalidDataException.

When the text is long and AllowScroll is false, the text will be visible, but will be misplaced. The issue is caused by the length of the text because the same field with a shorter text that can fit in the widget's rectangle will be displayed correctly.

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.

When a paragraph has defined tab stops in its style and has the same tab stops locally cleared, the tab stops are still respected when exporting to PDF. Instead, cleared tab stops should not be respected.

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

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.

Removing/adding rows/columns inside a worksheet requires all the data after them to be translated according to the change. This operation is slow and affects editing performance.

Endless loop on PDF export when an empty string is assigned to text fields with no source /V and auto-sized default appearance (/DA with 0 Tf).

Workaround: Instead of an empty string (""), set the value to null. Or don't set it at all and leave it unmodified.

There are many instances of the internal Transition, State and ImageXObject classes.

Center alignment is not respected for list numbering.

Actual:

When two PDFs containing AcroForm fields are merged with PdfStreamWriter, the generated PDF contains page widget annotations whose parent field dictionaries are not correctly registered in the document-level /AcroForm/Fields tree.

The issue is reproducible by merging the same four-page form twice. The resulting PDF contains all widget annotations, but PDF viewers do not resolve the second form’s interactive fields correctly.

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

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

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

InvalidDataException is thrown when importing an XLS document with malformed compressed picture data in the drawing layer.

Error 141 TYPECHECK on Lexmark printer when printing DPL-generated PDF file.

Merging/importing PDFs with duplicate field names can create one logical RadioButtonField containing widgets from multiple source field nodes. The first node initializes its widget options. Reused duplicate nodes can add additional widgets without assigning RadioOption instances.

The widgets then contain valid "/Off" appearance states, but their model Option property is null. During export, FieldPropertiesExporter accesses widget.Option.Value, causing a "NullReferenceException: Object reference not set to an instance of an object."

Exporting to PDF of a table with a first cell having preferred width of 100% and a second cell having preferred width of auto will result in missing the second cell.
