This can't be done, you have to manually update it. Document is not a DependencyProperty.
这是无法完成的，您必须手动更新它。文档不是 DependencyProperty。

Here is the solution I came up with. I created a custom RichTextViewer class and inherited from RichTextBox.
这是我想出的解决方案。我创建了一个自定义 RichTextViewer 类并继承自 RichTextBox。
using System.Windows.Documents;
using System.Windows.Markup;
using System.Windows.Media;
namespace System.Windows.Controls
{
public class RichTextViewer : RichTextBox
{
public const string RichTextPropertyName = "RichText";
public static readonly DependencyProperty RichTextProperty =
DependencyProperty.Register(RichTextPropertyName,
typeof (string),
typeof (RichTextBox),
new PropertyMetadata(
new PropertyChangedCallback
(RichTextPropertyChanged)));
public RichTextViewer()
{
IsReadOnly = true;
Background = new SolidColorBrush {Opacity = 0};
BorderThickness = new Thickness(0);
}
public string RichText
{
get { return (string) GetValue(RichTextProperty); }
set { SetValue(RichTextProperty, value); }
}
private static void RichTextPropertyChanged(DependencyObject dependencyObject, DependencyPropertyChangedEventArgs dependencyPropertyChangedEventArgs)
{
((RichTextBox) dependencyObject).Blocks.Add(
XamlReader.Load((string) dependencyPropertyChangedEventArgs.NewValue) as Paragraph);
}
}
}

You can use the InlineUIContainerclass if you want to bind a XAML control inside of an inline typed control
InlineUIContainer如果要在内联类型控件内绑定 XAML 控件，可以使用该类
<RichTextBlock>
<Paragraph>
<InlineUIContainer>
<TextBlock Text="{Binding Name"} />
</InlineUIContainer>
</Paragraph>
</RichTextBlock>
