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.

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.

Pressing Delete at the end of a paragraph leads to merging the content of the current paragraph with the next block. However, when the deleted paragraph contains a single space, the layout stops updating after pressing Delete.

Steps to reproduce:

1. Create two tables with paragraph between them

2. Add a space to the paragraph

3. Press Delete (when the caret is just after the space)

Observed: The layout is not updated after this and further modifications


Workaround: 
Delete the space before deleting the paragraph:

private void RadRichTextBox_CommandExecuting(object sender, Telerik.Windows.Documents.RichTextBoxCommands.CommandExecutingEventArgs e)
{
    if (e.Command is DeleteCommand && this.radRichTextBox.Document.Selection.IsEmpty)
    {
        Paragraph currentParagraph = this.radRichTextBox.Document.CaretPosition.GetCurrentParagraphBox().AssociatedParagraph;
        if (currentParagraph.Inlines.Count==1 && string.IsNullOrWhiteSpace((currentParagraph.Inlines.First as Span).Text))
        {
            this.radRichTextBox.Delete(true);
        }
    }
}

When cross-reference is added in the header/footer of a document in does not show the available options from the document.

WMF contains both bitmap and vector elements and currently RTB supports only the bitmap parts. We should consider adding support for the vector elements as well.
