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

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

 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);
}

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:

Add support for document comparison

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.

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.

Hello

Calling MailMerge on a document with a nested repeating group throws NullReferenceException when a merged value contains a line terminator.

All of the following are required to reproduce the crash:

• The group («BeginGroup:Items» … «EndGroup:Items») is nested inside an outer group
• The field whose value contains the newline sits in a later table cell than the group's begin marker
• The value belongs to a non-last record

I have attached a minimal repro demonstrating the bug.

Empty paragraphs are exported to PDF with a bigger font size.

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.

Center alignment is not respected for list numbering.

Expected:

Actual:

Text is exported to PDF with a larger font size when it has a paragraph style linked to a character style with a fixed size.

Add support for exporting shapes to PDF.

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.

This is happening because the cell with preferred width 100% takes all the available width and all other columns are rendered with no available width which causes the height of the table to grow big.

WORKAROUND: Either clear the cell PreferredWidth property or set it to value which is smaller than 100%.
