Wpf RichTextBox 包装问题 [英] Wpf RichTextBox wrapping problems

问题描述

我在 WPF 的 RichTextBox 中遇到文本换行问题，当我得到如下文本时:

I am having a problems with text wrapping in WPF's RichTextBox, when I get the text like:

  TextRange tr = new TextRange(rtb.Document.ContentStart,
                               rtb.Document.ContentEnd);

tr.Text 没有任何\r\n"，但在视觉控制中它看起来应该是(当输入到达 RichTextBox 边界时它会换行(插入行尾)).

tr.Text doesnt have any "\r\n", but in visual control it looks like it should be (it wraps when input reaches RichTextBox border (inserts end of the line)).

我像这样创建 RichTextBox:

I create RichTextBox like this:

 <RichTextBox Name="Rtb"  AcceptsReturn="True" AcceptsTab="True"   VerticalAlignment="Stretch" HorizontalAlignment="Stretch"  
    HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" Height="100" Margin="15,125,5,45"  Width="272">
            <FlowDocument  LineHeight="1" IsColumnWidthFlexible="true" >
                <Paragraph LineStackingStrategy="MaxHeight">
                    <Run Text="RichTextBox"/>
                </Paragraph>
            </FlowDocument>
 </RichTextBox>

推荐答案

您必须将 RichTextBox 放置在 ScrollViewer 中.

You have to place the RichTextBox in a ScrollViewer.

<ScrollViewer>
   <RichTextBox>
        ...
   </RichTextBox>
</ScrollViewer>
