从WPF中的RichTextBox显示LineNumbers

Question

我找到了一个例子,如何RichTextBox在Windows窗体中显示LineNumbers . http://www.codeproject.com/Articles/38858/Line-Numbers-for-RichText-Control-in-C

在WPF中有人为它做一个例子吗？

编辑:

是否有人与AvalonEdit合作,因为他想在他的程序中显示LineNumbers并且可以通过我的问题帮助我.

Answer 1

我想只是添加一个简单的解决方案......

Avalon(下载)已被提及,这里是如何用它做行行:

<avalon:TextEditor ShowLineNumbers="True" Width="500" Height="500"
                    Text="some more test&#10; some more test&#10; some more test&#10; some more test&#10; some more test&#10; some more test&#10; some more test&#10; some more test&#10; some more test&#10; ">
</avalon:TextEditor>  

它是一个非常强大的编辑器 - 我在它和生产(自定义语言编译器等)中做了很多.它是免费的,所以它有它的'怪癖',但它允许你做你需要的任何东西.我不确定你在谈论哪种格式的文本 - 但是你需要的任何东西都可以完成,而且代码行数不多,如果你知道如何注入,你可以添加自己的发生器,变换器,几乎任何视觉效果,代码完整性等等 - 我对它没有任何既得利益:)

用于语法突出显示的小样本:

<avalon:TextEditor 
  ShowLineNumbers="True" 
  SyntaxHighlighting="C#" Width="500" Height="500"
  Text="void Test(int id, string name)&#10;{&#10;&#09;name = name + id.ToString();}" />  

"XmlDoc", "C#", "JavaScript", "HTML", "ASP/XHTML", "Boo", "Coco", "CSS", "C+", "Java", "Patch", "PHP", "TeX", "VBNET", "XML"从代码中我可以看出支持.

如果你想实现自己的自定义syntax highlighting(Avalon编辑器是高度可扩展的 - 有关详细信息,请参阅提到的代码项目文章)...

你需要定义自己的IHighlightingDefinition,然后用HighlightingManager代码注册它- 然后添加一些东西来补充.但这本身就是一个很长的故事.

只需为TextBox使用自定义模板; 以下答案可能对您有所帮助:

TextBlock的可见行数

更改答案以获得OP预期的工作.

<Style x:Key="Local_TextBox" TargetType="{x:Type TextBoxBase}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type TextBoxBase}">
                <Border Name="Border" Background="{TemplateBinding Background}">
                    <ScrollViewer x:Name="PART_ContentHost" />
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

设计师,

<DockPanel>
    <TextBlock Text="{Binding ElementName=uiTextBox, Path=(local:AttachedProperties.BindableLineCount)}"/>
    <TextBox x:Name="uiTextBox" TextWrapping="Wrap" local:AttachedProperties.HasBindableLineCount="True"
            AcceptsReturn="True" Text="{Binding LongText}" Style="{StaticResource Local_TextBox}" />
</DockPanel>
