WP8:RichTextBox 没有 Document 属性 [英] WP8: RichTextBox has no Document property

问题描述

所以我在我的 WP8 项目的 xaml 页面上有一个 RichTextBox，设置如下:

So I have a RichTextBox on my xaml page in my WP8 project, set up like this:

<RichTextBox x:Name="ContentDisplay" IsReadOnly="True">

</RichTextBox>

我试图让它显示一些文本.我在网上找到的每一段代码都引用了 Document 属性.但是，当我尝试用它做任何事情时，它就是不存在.没有

I'm trying to get it to display some text. Every single piece of code I find on the net references Document property. However, when I try to do anything with it, it just isn't there. There's no

var test = ContentDisplay.Document;

设置为.

当我尝试使用上述行编译项目时，出现以下错误:

When I try to compile the project with aforementioned line, I get a following error:

'System.Windows.Controls.RichTextBox' does not contain a definition for 'Document'
and no extension method 'Document' accepting a first argument of type 'System.Windows.Controls.RichTextBox' could be found 
(are you missing a using directive or an assembly reference?)   

试图用谷歌搜索它，我发现引用了一个类似但不一样的问题，这一次人们试图使用文本"属性(与文档属性不同，它甚至不存在)那么，请告诉我如何使用该控件?

Trying to google it, i find references to a similar but-not-the-same problem, this time with people trying to use 'Text' property (which, unlike Document property, doesn't even exist) So, please tell, how can I use that control?

推荐答案

您可以使用 Blocks 和 Paragraphs 向该控件添加内容.下面将向 RichTextBlox 添加另一行.

You add content to this control using Blocks and Paragraphs. The following will add another line to the RichTextBlox.

var paragraph = new Paragraph();
paragraph.Inlines.Add("Hello");
richText.Blocks.Add(paragraph);

<RichTextBox x:Name="richText">
  <Paragraph>
    <Run Text="Line one" />
  </Paragraph>
</RichTextBox>

文档属性在控件的 Silverlight 版本上可用.不幸的是，并非所有功能都移植到 Windows 手机.

The Document property is available on the Silverlight version of the control. Unfortunately, not all features were ported to windows phone.
