如何在 UWP 应用中保留 TextBlock 的空白 [英] How to preserve white-spaces of TextBlock in UWP apps

问题描述

如果您只是将 TextBlock 中的 Text 属性的值设置为示例 "(请注意，此字符串的 end 处有 3 个空格)，TextBlock 会显示什么在 UI 中只是示例".

If you simply set the value of Text property in a TextBlock as "Example   " (Note that there 3 whitespaces at the end of this string),what TextBlock shows in UI is just "Example".

并且在网上搜索了解决方案后，发现有办法解决这个问题:

And after searching for solutions on the Internet, I found that there is a way to solve this issue:

<Border BorderThickness="1" 
        BorderBrush="#FFFF0202" 
        HorizontalAlignment="Center" 
        VerticalAlignment="Center">
    <TextBlock x:Name="t1">
        <Run Text="Example&#160;&#160;&#160;"/>
    </TextBlock>
</Border>

以上代码展示了TextBlock的Inline属性的使用， 在Run的Text中正确显示了空白.

The above code shows the use of Inline Property of TextBlock and   in Run's Text displays the whitespace correctly.

但是，在我的情况下，我需要在 Code-behind(或通过 DataBinding) 中设置 TextBlock 的 Text 属性，上面的技巧不起作用，它显示 UI 中的示例   .

However, im my case I need to set the Text property of TextBlock in Code-behind(or via DataBinding), the trick above doesn't work and it shows Example    in UI.

我尝试通过数据绑定设置Run的Text属性的值，我认为可以正确显示转义字符，但是Run的Text属性不是依赖属性，所以我没有更好的方法来解决这个问题.

I tried to set the value of Run's Text property by data binding, which I think can displays the escape character correctly, but Run's Text property is NOT a dependency property so I have no better way to solve this.

(但是我认为使用 TextBlock 的 padding 属性也是一个技巧，它应该可以工作.但是还有更好的方法吗?)

(However I think use padding property of TextBlock is also a trick to do this, and it should work. But there is any better way to do ?)

推荐答案

首先，Run.Text 确实支持数据绑定.

First, Run.Text does support data binding.

  在数据绑定中无法正确打印的原因是它使用了 XML 转义字符.

The reason that   doesn't print correctly inside data binding is because it's using XML escape characters.

尝试使用 (char)160 -

public string TestString { get; set; } = "Example" + (char)160 + (char)160 + (char)160;

<TextBlock>
    <Run Text="{x:Bind TestString}" />
</TextBlock>
