When the span properties are modified (e.g. a highlight color is applied), they should not affect the span properties of the text inserted after that.

This applies for all span properties. Here are a part of them:

- Highlight color

- Foreground color

- Font weight

- Font family

- Font style

Currently, all the properties applied to the current span are inherited when the user starts typing next to it.

Implement an option for controlling how the list-style-type of a list will be exported to the HTML format.

The same issue is observed with heading styles. 
The HtmlExportSettings property PropertiesToIgnore can't be used to control how the paragraph or character properties of a list will be exported.
Steps to reproduce:
Create a document with a list of different levels.
Set fp.ExportSettings.PropertiesToIgnore["li"].Add("margin-left");
Export to HTML.
Observed: The PropertiesToIgnore doesn't work for paragraph properties of a list.

XamlParseException is thrown when importing revision date time of track changes which is exported with different than invariant culture.

Steps to reproduce: 
Set the current thread culture to "new CultureInfo("nb-NO")"
Turn on track changes.
Start the RTB and enter some text.
Export to XAML.
Import the previously exported XAML file.
Observed result:  XamlParseException is thrown when parsing the revision date time object.

The default indentation of the list bullets is different when shown in the RadRichTextBox and when exported to HTML and shown in a web browser.
There is a screenshot attached showing how the result is rendered in a web browser.

When the user enter text using the keyboard the PositionChanged event of the CaretPosition is not fired.
The item's status changed to Declined - the LocationChanged event can be used to track when the location of the position has been changed.

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.

Available in R1 2018 SP2 release version.

MS Word clears the character style property of a span when a new value equal to the default value is applied. This is applicable only when the span or the parent paragraph does not have associated style which has a local property defined for the same style property.

In some cases when an image is copied from an external source and pasted in the rich text box, the image is not displayed. This is caused by the Clipboard.GetImage() method used internally by the control. 

To work this around, you can subscribe for the CommandExecuting event of RadRichTextBox and manually get the image from the clipboard.

private void Rtb_CommandExecuting(object sender, Telerik.Windows.Documents.RichTextBoxCommands.CommandExecutingEventArgs e)

{
	PasteCommand command = e.Command as PasteCommand;
	if (command != null && (Clipboard.GetData("DeviceIndependentBitmap") != null))
	{
		//Get the image stream from the clipboard.
		//You can check the following blog post for an approach which you can use to get the image properly:
		//https://www.thomaslevesque.com/2009/02/05/wpf-paste-an-image-from-the-clipboard/
		this.radRichTextBox.InsertImage(imageStream, "jpeg");
		e.Cancel = true;
	}
}	

The normal hyphen should break the line and the non-breaking hyphen (inserted with: alt+0173) should not break the line

StackOverflowException is sometimes thrown while a document containing annotations is updated in the main thread (e.g. by typing in it), and spell checking is enabled.

The exception is thrown in a background thread, which call stack similar to this one:

The bookmark decoration square bracket is visualized in a previous table cell if the parent table does not have content. 
The visualization of the ending bracket does not affect the location in the document of the bookmark range end.

Steps to reproduce:
Insert an empty table 3x3.
Select the entire table.
Insert bookmark.
Toggle the bookmarks. RadRichTextBox has a ToggleBookmarks method which will visualize or hide the bookmark surrounding square brackets.

You can also check the attached screenshot.

Handwriting keyboard allows you to enter text with a pen or other stylus. This is currently not implemented in RichTextBox and when you are using handwriting keyboard, the text is inserted more than once when the stylus is lifted while writing.

The dialog should match the strings contained in the different document parts (headers, footers, footnotes, endnotes, comments).

All bullet list levels are exported to HTML with list-style-type:disc. Instead, they should be exported with list-style-type:disc, list-style-type: circle;, and list-style-type: square; depending on the level - Level 1,4,7 are with disc, level 2,5,8 are with circle, and level 3,6,9 are with square for the default bullet list type.

Note: There are more problems with the HTML export/import roundtrip in this use case: 

- indents FirstLineIndent, RightIndent, Left are set locally - this prevent the expected changing of indent when changing the list level.

- formatting of the bullet (font for example) is set to the paragraph.

Steps to reproduce:
- Add bullet list with three levels.
- Export to HTML.
Expected: The browser show the list preserving the bullet styles.
Actual: The browser visualizes the list with different bullet styles.

The exception is thrown when performing undo of a section break, immediately followed by a table, and the second section is separated between more than one section layout box.

Workaround: Ensure there is a paragraph between the break and the table.

The header of the first page can have only settings applied without any content. In such scenarios, RtfFormatProvider doesn't import the whole header, which can lead to a different layout of the document.

The settings of the empty paragraphs in the document fallback to the default document settings (Verdana).

The EnumerateChilderOfType() method can be used to traverse all the paragraphs in the document and apply them the same font family as a workaround.

For some font sizes, the end of the last letter or the start of first letter is clipped. The problem is most visible with italic styles and large font sizes, but is present even for small sizes and regular style.

NullReferenceException is thrown when a hyperlink is removed from the document while the user is hovering it with the mouse. Such cases are when hyperlink is removed from the context menu, or when TOC field containing hyperlinks is updated from the context menu.


The exception is with the following call stack: 

ErrorMessage: Object reference not set to an instance of an object.
StackTrace:    at Telerik.Windows.Documents.UI.UIProviders.HyperlinkUIProviderBase.UIElement_MouseEnter(Object sender, MouseEventArgs e)
   at System.Windows.RoutedEventArgs.InvokeHandler(Delegate handler, Object target)

   ...

If the mouse hovers the hyperlink a moment later, exception is not observed. The situation when the mouse is over a hyperlink is not so uncommon:

- When the user operates hyperlink context menu with the keyboard and removes the hyperlink

- when there are multiple items in the ToC, there is great probability for the mouse to be over a hyperlink which is just below the Update Field button in the context menu - and when the context menu disappears, the mouse gets over the hyperlink.

Fix available in LIB Version 2017.2.529.
