When a conditional table style is applied to a table and the document is exported to RTF format, when the exported document is opened in MS Word, the FontWeight and ForeColor properties are not respected.

Examples:
If Grid Table 4 style from the gallery is applied and the document is exported and opened in MS Word, the FontWeight property is not respected and the text is not bolded.
If Grid Table 5 Dark style from the gallery is applied and the document is exported and opened in MS Word, the FontWeight and ForeColor properties are not respected.

The ImagesDeflaterCompressionLevel and ContentsDeflaterCompressionLevel in the PdfFormatProvider's export settings have 0 for default value instead of -1.

Workaround: Change the settings's properties to -1 explicitly.

When there is applied a local font family, the font family of the theme should be set to none. Otherwise, the font family of the elements that have a local value will be changed.

Workaround: Reset the theme font family after import: 

this.radRichTextBox.Document.Style.SpanProperties.ThemeFontFamily = Telerik.Windows.Documents.Model.Themes.ThemeFontsEnum.none;

Each time the Styles Gallery becomes visible it triggers an update of each style which leads to increased CPU usage. Significant performance delay is not experienced as the update is executed in dispatcher and with delayed execution. However, a blink of the styles could be noticed.

This includes everything related to:

- Navigation of the controls only with keyboard (Tab, Shift+Tab, arrows, Alt+<Letter>)

- Correct Screen Reader pronunciation when entering into/navigating in the control, including RadRichTextBox itself. 

If an Rtf document is imported and then exported to a Docx file, every single paragraph has associated list when the document is opened in MS Word.

Workaround: Before the document export, clear the ListId property:
if (this.radRichTextBox.Document.Style.ParagraphProperties.ListId == -1)
{
    var property = this.radRichTextBox.Document.Style.ParagraphProperties.GetStyleProperty(Paragraph.ListIdProperty);
    property.ClearValue();
}

When exporting to HTML, each two consequent spaces in a run are treated as  . However, when a style is applied to one of the spaces, the span is split and the two spaces are not considered as a pair, therefore, the HtmlFormatProvider exports them as normal spaces.

When the two spaces are the whole content of a paragraph, this paragraph is not visible when the HTML is visualized in a browser. 

Currently list styles cannot be removed from the document model.

There is no command or API in the editor for deleting paragraph, but there is such for, for example, deleting table. 

ArgumentOutOfRangeException is thrown when replacing all (Replace All button is clicked from the FindReplace dialog) occurrences of given text if the replace text is with smaller length than the searched text. 

For example if we have the following text written in the RadRichTextBox: "Some Text" and we want to replace all occurrences of "Some Tex" with "AA" (open find and replace dialog and click ReplaceAll button), the exception occurs

Workaround: Change the FindReplaceDialog with a custom one (see how in this SDK demo - https://github.com/telerik/xaml-sdk/tree/master/RichTextBox/CustomFindReplaceDialog ). In the new custom dialog, buttonReplaceAll_Click event handler, change the initialization of the 'startFindPosition' variable to be in the body of the while loop.

Available in LIB Version 20181.205.

When a table is the only content in a document and is copy/pasted, it is inserted in the copied table as nested. The issue is observed only when the table is the only content in the table. It is not observed when an empty paragraph is available before the table or any spacing is inserted after the table.

To workaround the issue, the selected table could be deleted before pasting.

Watermark is drawn for each page in the RadDocument. When the watermark is a larger image, an OutOfMemoryException might occur during export to PDF. The same applies for images in header/footer.

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.

Stretching the text is done by modifying the Scale Property of the Character Spacing properties. In the Office Open XML specification, it is represented by the <w:w w:val="300"/> tag. 

The case "margin: 0px" is imported only as margin-top. This results in spacing-after property of the paragraph to have an incorrect value.

There is a possible workaround if you have control over the construction of the HTML. Change the "margin: 0px" to "margin: 0px 0px 0px 0px"

If content with DocumentLists and ListStyles respectively, is copied from Microsoft Word and then pasted in RadRichTextBox, ArgumentNullException is thrown while the lists from the DocumentFragment are fixed (FixListStyles() method). 

The exception is caught and thus, the content from the clipboard is not inserted during the copy/paste operation. In some cases, when the content is pasted again, the content is pasted.

Workaround: Replace the fragment in the clipboard with one that is already "fixed". See the attached MainWindow.cs.txt

InsertTableRowAbove/Below and DeleteTableRow commands now are disabled when there is selection. This makes them inconvenient for the following scenarios:
- Insert multiple rows
- Delete multiple rows

Also, when multiple rows are selected and InsertTableRowAbove/Below is executed, is should add the same number of rows.

The commands that toggle different span styles (bold, italic, underline, strikethrough) stop working after using them several times on different ranges of cells. If a single cell is selected, the span could be properly changed.

The issue is reproducible with 2013 Q1 version and newer. It is not observed with version 2012 Q1.

The UI indicates that a strikethrough is applied, but it is not visible in the document. 

Workaround: 

Reorder the UI layers of RadRichTextBox so that the one responsible for drawing the strikethrough decoration is added in a higher position: 

protected override void BuildUILayersOverride(IUILayerContainer uiLayerContainer)
{
    uiLayerContainer.UILayers.Remove(DefaultUILayers.StrikethroughDecoration);
    uiLayerContainer.UILayers.AddAfter(DefaultUILayers.UnderlineDecoration, new StrikethroughTextDecorationUILayer());
} 

When the LevelText of the list style is empty, PdfFormatProvider throws an IndexOutOfRangeException while trying to draw the bullet.

Workaround: Ensure that the LevelText of the ListItemStyle is not an empty string:

foreach (ListStyle listStyle in this.radRichTextBox.Document.ListManager.GetAllListStyles())
{
    foreach (ListLevelStyle level in listStyle.Levels)
    {
        if (string.IsNullOrEmpty(level.LevelText))
        {
            level.LevelText = " ";
        }
    }
}
