The FlowDocumentReader element is used to create a FlowDocumentReader in XAML.
<FlowDocumentReader>
Document
</FlowDocumentReader>
To load a document in a FlowDocumentReader, we simply set its content to a FlowDocument. A FlowDocumentReader can host one FlowDocument only. The following code snippet loads a FlowDocument in a FlowDocumentReader.
<FlowDocumentReader>
<FlowDocument>
<Paragraph FontSize="20" FontFamily="Georgia" FontWeight="Bold" Foreground="DarkBlue">
Tutorial: WPF RichTextBox Control
</Paragraph>
</FlowDocumentReader>
