The ChangeListStyleCommand has an event named ListStyleChangedChanged  which is never raised.

If span formatting command (bold, italic, strikethrough) is applied to selection over multiple paragraphs, and tracked with tracked changes; and later this tracked change is rejected, NullReferenceException is thrown. The exception is handled so the visible result for the end user is that the UI stops updating and any subsequent changes are not visible.

When header/footer (HeaderFooterPresenterBase) is rendered, the model which corresponds to it (HeaderFooterBase's Body property) is not updated. The result is updated only in the presenter. Thus, when exporting the document or when checking the elements in the model, the value of the inline (span's text) is not updated.

Workaround: Update the fields in the headers/footers. RadDocumentEditor.UpdateAllFields() method can be used. Note that it works only for the main document and not its child documents, so different RadDocumentEditors should be created for each header/footer document.

If there is a Span surrounded with annotation ranges in a table cell and the table has conditional table style, the text cannot be selected after import of such document. If the table has normal table style (not a conditional one) everything works as expected. 

- If the annotations are bookmark ranges (start and end), the text cannot be selected with double-click over the text.
- If the text is hyperlink, the text could be selected with double-click, but when the selection is changed through the keyboard arrows, the same issue appears.

The issue appears with Docx documents, in addition to the attached Xaml one, so the issue seems not to be related to the XAML serialization.

Trying to delete table cell formatting symbol, when track changes are on, will result in marking the text in the cell as deleted.
MS Word does not respect such delete action.

When importing a hyperlink containing anchor, the NavigateUri keeps the part after the hyperlink only instead of the whole URI.

If we have a paragraph containing single span which has set red foreground as a local value, applying 'Heading 1' style on that paragraph from the RadRichTextBox' Styles Gallery doesn't change the span's foreground to blue (which comes from the applied style), but preserves the red value.

Workaround: To clear a given property, basing on some logic which determines if it should be cleared. For example:
this.radRichTextBox.CommandExecuting += (s, e) =>
 {
     if (e.Command is ChangeStyleNameCommand)
     {
         var style = this.radRichTextBox.Document.StyleRepository.GetValueOrNull(e.CommandParameter.ToString());
         if (style.Type == Telerik.Windows.Documents.Model.Styles.StyleType.Paragraph)
         {
             Paragraph paragraph = this.radRichTextBox.Document.CaretPosition.GetCurrentParagraphBox().AssociatedParagraph;
             foreach (Span span in paragraph.EnumerateChildrenOfType<Span>())
             {
                 span.ClearValue(Span.ForeColorProperty);
             }
         }
     }
 };

The issue is reproducible when the document contains a custom Paragraph style the ListId of which related to a custom ListStyle in the document.

Empty paragraph containing only a section break shouldn't be translated on the next page if there isn't enough space for it on the current page.

NullReferenceException is thrown when deleting content. The delete action is executed over a selection. The selection starts from the middle of a paragraph and ends in a table. The paragraph should have a line break as a first element.

If the document contains lists with applied customs style, when trying to open the Manage Styles Dialog using the button in the ribbon, ArgumentNullException is thrown and handled internally, and the dialog is not opened. If the user clicks the button multiple times (the number of lists with custom styles), the dialog is opened.

Steps to reproduce:
1. Create a custom list style.

2. Add some test text in the RadRichTextBox.

3. Apply the custom list style in two places in the document.

4. Click on the Change Styles button.

Observed: Dialog is not opened.

Expected: The dialog should open.

Table indent property could not be styled through style as it receives a local value with the insertion of the table

Rtf document cannot be imported when it has an empty table row which have row spanned cells only.

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());
} 

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"

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.

When a document is imported from HTML, we set locally to the span elements Times New Roman as a font family nevertheless it is not declared anywhere. The same applies for the font size as well - it is set to 12.

Workaround: Clear the FontFamily property after import

foreach (Span span in this.radRichTextBox.Document.EnumerateChildrenOfType<Span>())
{
    span.GetStyleProperty(Span.FontFamilyProperty).ClearValue();
    span.GetStyleProperty(Span.FontSizeProperty).ClearValue();
}

The layout of the document goes to infinite cycle and the whole application freezes when specific combination (it's not exactly identified) of sections and section column breaks is present in the document. Sometimes UI may freeze when the document is trying to render for first time.

The style of the table fallbacks to the default one and when the content of a cell is deleted, the current font family and font size are changed. The scenario is working as expected in versions before R3 2016.

The formatting(font size) of a line break is changed to the document default after adding a single paragraph before the line break. However, the current span style will be changed to the default formatting after adding several paragraphs with a text before a line break. This results in adding the next paragraphs with document default formatting instead of the current span style. The problem is reproducable only in flow mode.
Note: the document default style formatting should be different from the formatting of the line breaks.
