Open the Demo application >> RichTextEditor>> First Look example and open and empty document. Keep a random key pressed. You are expected to observe delayed text input:
RichTextEditor: Lists are always exported to HTML with Verdana font.
Changing the normal style or setting the DocumentInheritsDefaultStyleSettings has no effect.
Use the code below.
1. Click the first button to insert a link.
2. Click inside the link to move the cursor.
3. Click the second button to insert the yellow rectangle
4. Click the third button to export the HTML content.
Actual result: StackOverflow exception occurs

If you remove the last span of a paragraph (on a measured document), using the inline collection, a NullReferenceException is thrown.
As a workaround: either make sure the manipulation happens on a non-measured document, or remove the span by using the RichTextEditor's API:
this.radRichTextEditor.Document.Selection.AddDocumentElementToSelection(span);
this.radRichTextEditor.Delete(false);
Add Korean language to your machine:
Then type 'rkskekfk'. The expected symbols are: "가나다라". However, if you try selecting the entered text, the last symbol disappears:
The colspan="0" has special meaning according to the HTML specification http://www.w3.org/TR/html401/struct/tables.html:
-------------------
colspan = number [CN]
This attribute specifies the number of columns spanned by the current cell. The default value of this attribute is one ("1"). The value zero ("0") means that the cell spans all columns from the current column to the last column of the column group (COLGROUP) in which the cell is defined.
-------------------
Workaround: Preprocess the HTML, and delete all occurrences of colspan="0".
When a document is imported from HTML, we set locally to the span elements Times New Roman nevertheless it is not declared anywhere. This breaks the document view if for example we decide to change the RadDocument's default font family or even the NormalWeb style's font. The same applies for the font size as well.
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();
}
Steps to reproduce:
1. Import the following html:
this.radRichTextBox.Document = new HtmlFormatProvider().Import(@"<h1>Hello</h1><h2>World</h2><p>Lorem ipsum<p>");
2. Set the document's default font family to Comic Sans MS:
this.radRichTextBox.Document.Style.SpanProperties.FontFamily = new FontFamily("Comic Sans MS");
Observe: The font in the document is Times New Roman
Expected: The font should be Comic Sans MS
When changing the theme through ThemeResolutionService.ApplicationThemeName all the application gets changed. Except the ForeColor of the RadRichTextEditor does not get change. Hence the box displays black text on a dark background. Quite unreadable.
Assigning the theme directly in the designer makes everything renders ok.
Sample application attached.

The default browser paragraph spacing is not preserved during HTML import-export.
Workaround:
StyleDefinition normalStyle = this.radRichTextEditor1.Document.StyleRepository[RadDocumentDefaultStyles.NormalWebStyleName];
normalStyle.ParagraphProperties.SpacingAfter = 20;
normalStyle.ParagraphProperties.SpacingBefore = 20;
- Tab
- Space
- Nothing (none following character)
In OOXML, this is described using the 'suff' element.
In MS Word, this setting could be changed by selecting the bullet/number of the list item -> Context Menu -> Adjust List Indents -> Follow number with:.
Importing this:
<p>This is a paragraph.</p>
<p>
This is a paragraph.
</p>should import two identical paragraphs, but it actually import it like this:
This is a paragraph. This is a paragraph.
It has a leading space before the second paragraph.
