Importing a structured document tag (content control) that contains a data binding in its properties, which has no prefix mappings defined causes an exception during document layout.

Instead of moving the position after the content control, the caret goes on the last position in the control. This behavior affects keyboard input negatively, as users need to manually navigate to the right.

CheckBoxes defined on block level (i.e. wrapping a table cell) cannot be manually clicked at run-time.

Importing structured document tags with auto-close SdtContent tag throws InvalidCastException exception

Provide API for enforcing the use of only FIPS 140-2 compliant hashing algorithms

Implement a MarkdownFormatProvider, which will allow import/export from/to markdown format.

In MS Word, the users can change the background color of the page. 

A 'w:background' property is applied to the whole document in DOCX, and this property is used as a page color in Paged layout mode, and as a background color in Web layout mode. 

When implementing, think of whether RadRichTextBox.Background should be synchronized with this property when RadRichTextBox.DocumentInheritsDefaultStyleSettings is true.

Workaround: Currently, background could be set using RadRichTextBox.Background property in Web layout mode, and using a custom style, as described in When the LayoutMode is Paged the Background forum thread, in Paged layout mode.

 

When a content control check box updates it state at run-time, any local formatting is lost.

Workaround: Formatting defined in style definition is properly kept.

If the main document part of a DOCX document is with name different than "document.xml", for example "document2.xml", the content of the document is not imported. 

Such documents are created by OpenXML SDK, if for example this tutorial is followed:

The table is not properly resized when using the left-most border. The table should be resized like in MS Word (see attached).

This works in MS Word and the comments are exported at the bottom of the document

Currently HtmlFormatProvider does not export/import tables with alignment (left, center, right).

Nested tables inherit alignment from its parent table or table cell when importing a document from HTML, but they shouldn't.
The paragraphs are also aligned incorrectly when their parent table has its align attribute set.

When changing the names of the style and export to RTF the style names are duplicated when imported again

Xaml exported in Net Core app cannot be imported with Net Framework app

 The paragraph which has run with vanish attribute is not imported from docx

Copying a Table and then pasting it as plain text results in each table cell added on a new line. Instead, the content of the cells on a single table row should be separated by tabs and newlines should differentiate the table rows.

When pasting a copied image with Keep Text Only paste option an exception is thrown (check the attached record.gif)

Pressing 'a'+Enter simultaneously while in Japanese IME leads to en exception with the following message: Value cannot be null. Parameter name: insertIMETextCommandContext.

Currently, inserting a code block is processed by the RichTextBox's InsertCodeBlock() method which takes the whole code block at once. This leads to UI freezing when the code block is very long.
