WPF RichTextBox word wrapping
提问by Stefan
I am trying to display a large amount of data in a WPF RichTextBox control. My data contains space characters. There is a default word wrapping behavior that does not allow a "word", to be split and displayed on more lines.
我正在尝试在 WPF RichTextBox 控件中显示大量数据。我的数据包含空格字符。有一个默认的自动换行行为，不允许将“单词”拆分并显示在更多行上。
This behavior is triggered by having space characters, questions marks, full stops or any other sentence/word delimiter. In the example below, if you replace the space character with a letter ( ex: "X" ), everything will be displayed as expected. As no delimiter characters are found, the big "word" is allowed to be truncated and displayed on multiple lines.
此行为由空格字符、问号、句号或任何其他句子/单词分隔符触发。在下面的示例中，如果您用字母（例如：“X”）替换空格字符，则所有内容都将按预期显示。由于没有找到分隔符，所以允许大“词”被截断并显示在多行上。
Is there a way of disabling this word/sentence wrapping behavior?
有没有办法禁用这个词/句子包装行为？
This is the XAML code:
这是 XAML 代码：
<Window x:Class="StackOverQuestion_TextBoxWrap.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="535">
<Grid>
<RichTextBox Name="RichTextBox" />
</Grid>
</Window>
This is the cs code behind:
这是背后的cs代码：
public MainWindow()
{
InitializeComponent();
Random rnd = new Random();
RichTextBox.FontFamily = new System.Windows.Media.FontFamily( "Lucida Console" );
Paragraph par = new Paragraph();
for ( int i = 0 ; i < 6000 ; i++ )
{
Run run = new Run();
run.Text = rnd.NextDouble().ToString() + " " ;
par.Inlines.Add( run );
}
RichTextBox.Document.Blocks.Add( par );
}

I think you need to disable the word wrapping in the RichTextBox control, that is always enabled, according to the documentation in MSDN:
根据MSDN 中的文档，我认为您需要禁用 RichTextBox 控件中的自动换行，该控件始终处于启用状态：
Text always wraps in a RichTextBox. If you do not want text to wrap then set the PageWidthon the FlowDocumentto be larger than the width of the RichTextBox. However, once the page width is reached the text still wraps.
文本始终包含在 RichTextBox 中。如果您不希望文本换行，则将FlowDocument上的PageWidth设置为大于 RichTextBox 的宽度。但是，一旦达到页面宽度，文本仍然会换行。
There's no explicit property to disable it, and you can do something like this:
没有明确的属性可以禁用它，您可以执行以下操作：
richTextBox1.HorizontalScrollBarVisibility = ScrollBarVisibility.Visible;
richTextBox1.Document.PageWidth = 1000;
as suggested here.
正如这里所建议的。
