Exception when there are merge fields in the header/footer and one performs mail merge: 

Unable to cast object of type 'Telerik.Windows.Documents.Flow.Model.Header' to type 'Telerik.Windows.Documents.Flow.Model.BlockBase

The attached sample project below demonstrates a possible workaround for PAGE and NUMPAGES fields when exporting to PDF. The demo shows how to generate document from scratch containing PAGE and NUMPAGES fields and export it to PDF.

Find and Replace document elements with special characters.

• ^p - Paragraph Mark
• ^t - Tab Character
• ^? - Any Character
• ^# - Any Digit
• ^$ - Any Letter
• ^^ - Caret Character
• ^u - Section Character
• ^v - Paragraph Character
• ^c - Clipboard Contents
• ^n - Column Break
• ^+ - Em Dash
• ^= - En Dash
• ^e - Endnote Mark
• ^d - Field
• ^& - Find What Text
• ^f - Footnote Mark
• ^g - Graphic
• ^l - Manual Line Break
• ^m - Manual Page Break
• ^~ - Nonbreaking Hyphen
• ^s - Nonbreaking Space
• ^- - Optional Hyphen
• ^b - Section Break
• ^w - White Space

When inserting a section between two paragraphs the section parent is not correct.

Example:

Paragraph paragraph1 = editor.InsertParagraph();
Paragraph paragraph2 = editor.InsertParagraph();
editor.InsertSection();
Paragraph paragraph3 = editor.InsertParagraph();

Expected:

paragraph1.Parent == paragraph2.Parent
paragraph2.Parent  != paragraph3.Parent 

Actual:

paragraph1.Parent != paragraph2.Parent
paragraph2.Parent  == paragraph3.Parent 

When a break element is defined in the middle of a Run, DocxFormatProvider imports it at the end of the same run. For example, the following content: 

<w:r>
  <w:t>This is</w:t>
  <w:br/>
  <w:t xml:space="preserve"> a simple sentence.</w:t>
</w:r>

Results in "This is a simple sentence " + break element after it.

Introduce support for min-height. Currently, this property is skipped. 

If a document has runs with font size larger than the one set in the style of the paragraphs and this document is exported to HTML, the resulting paragraphs overlap.

When exporting to PDF a document containing Table merged into a TableCell an extra empty space below the inner table is added:

Wrongly exported table width when the table preferred width is set to fixed:

<w:tblW w:w="11160" w:type="dxa"/>

and it is greater than the available page width: 

<w:pgSz w:w="12240" w:h="15840"/>
<w:pgMar w:top="630" w:right="1440" w:bottom="540" w:left="1440" w:header="720" w:footer="720" w:gutter="0"/>

Available page width = 12240 - (1440 + 1440) = 9360

A possible workaround is to set the page width to Auto:

IEnumerable<Table> tables = document.EnumerateChildrenOfType<Table>();
foreach (Table table in tables)
{
	if (table.PreferredWidth.Type == TableWidthUnitType.Fixed)
	{
		table.PreferredWidth = new TableWidthUnit(TableWidthUnitType.Auto, table.PreferredWidth.Value);
	}
}
