When the control is used in NoXaml scenario and the required resources are merged in the resources of the Window/UserControl containing RadRichTextBox, XamlParseException is thrown at runtime with a message "Cannot find resource named 'thumbStroke'."
or
the App.Current.Resources.MergedDictionaries is cleared.

Workaround: Merge Telerik.Windows.Documents.xaml and Telerik.Windows.Controls.RichTextBoxUI.xaml in App.xaml.
or
Merge the resourced before initializing RadRichTextBox:
 App.Current.Resources.MergedDictionaries.Add(new ResourceDictionary()
            {
                Source = new Uri("/Telerik.Windows.Documents;component/Themes/Styles/ImageAdornerUIResourcesDictionary.xaml", UriKind.RelativeOrAbsolute)
            });


Fix available in R3 2017 Official Release version.

The customers need to customize the dialogs for opening and saving a file. For example, they need to set a default path or extension. With the current implementation, this can be achieved by customizing the commands. Expose an API allowing them to achieve that easily.

The "initial" CSS keyword applies the initial value of a property to an element. At this point, the result shown in RadRichTextBox can be unexpected as this value is not considered but the style evaluation falls back to the default styles defined for the control and doesn't consider the ones defined in the document style.

For example, setting background-color: initial; always results in black background.

There is a large performance hit when manipulating an area of the document with many annotation ranges in it.

When the width of the tab stop is set to a negative value, an ArgumentOutOfRangeException is thrown on import. Other applications handle this case and convert the value to a positive number.

Fix is available in LIB Version 2018.1.326.

Mail merge is not working for the first record in the items source when the items source is IEnumerable with deferred execution.

Workaround: convert the collection to list.

Replacing a word with the same word but with capital letters leads to an infinite loop in the FindReplaceDialog when the search and replace values are surrounded by spaces. For example, search for " and " and replace with " AND ".

Workaround: Create a custom dialog and modify the logic for replacing text.

In Windows 10 1709 Falls creators update there is an upgrade to Microsoft Edge, with which the copy from edge is changed:

1) no longer it is copied in "Rich Text Format"

2) the "HTML Format" data is formatted differently than before - different line separators and the whole html is placed into a single line (unlike before).

An additional line should be inserted between the inner div and the span where the first <br> is inserted.

A specific combination of document elements causes an infinite measure loop.

Implement support for the SET field.

The content of a page can be aligned vertically. In DOCX, this is a property of the section and is defined with the vAlign element.

<w:sectPr>
…
<w:vAlign w:val="center" />
</w:sectPr>

There is not defined behavior of tables without fixed column width in FlowNoWrap. They try to fill the unlimited space, so only tables with fixed width can be used in this mode. The expected behavior might be fitted column width to its content or auto fitted table width to window.

This can cause a hang of the application or unexpected behavior while working with the table (e.g. the thumbs for resizing the column width appear after the column border instead over it).

Workaround: Subscribe to CommandExecuted, get the inserted table and set a fixed width to it.

Currently, the underline is always exported as single. Add support for the other types that can be used in RadRichTextBox.

Currently, paragraphs that have applied a list style but their list level is set to -1 or another invalid value, cannot be imported due to an ArgumentOutOfRangeException. According to the specification, the scenario is invalid, though, in MS Word and WordPad, similar values are not respected.

Pasting HTML content causes RichTextBox to insert a paragraph break, even if the copied content did not include the end of the paragraph.

Steps to reproduce:
1. Copy the first few words in a paragraph from Internet Explorer
2. Paste into the middle of a sentence in the RichTextBox
Expected: The content is pasted inline
Observed: The content is inserted, but a paragraph break is inserted after the content

When an element refers to a style name of a style that is not present in the document, trying to export it with RtfFormatProvider leads to KeyNotFoundException. A similar document could be produced when copying content from MS Word.

The same case is working properly with the other providers as well as in WordsProcessing (check the related 133762).

Workaround: Check all the styles used in the document and remove the NextStyleName or LinkedStyle values that point to non-existing in the document styles.
