Having hardcoded text with a binding in a TextBlock
提问by Andreas Grech
In WPF, is there any way to have the Textproperty of a TextBlockto contain both hard coded text and a specific binding?
在 WPF 中，有没有办法让Texta的属性TextBlock同时包含硬编码文本和特定绑定？
What I have in mind is something along the lines of the following (ofcourse, the below doesn't compile):
我想到的是以下内容（当然，以下内容无法编译）：
<TextBlock Text="Number of Fans: {Binding Artist.Fans.Count}"></TextBlock>

There is, if you are on .Net 3.5 SP1
有，如果您使用 .Net 3.5 SP1
<TextBlock Text="{Binding Path=Artist.Fans.Count,
StringFormat='Number of Fans: {0}'}" />

In using the above approach:
在使用上述方法时：
<TextBlock Text="{Binding Path="Artist.Fans.Count,
StringFormat='Number of Fans: {0}'}" />
I found it somewhat restrictive in that I couldn't find a way to bold face inside the StringFormat nor could I use an apostrophe in the StringFormat.
我发现它有些限制，因为我找不到在 StringFormat 中加粗的方法，也无法在 StringFormat 中使用撇号。
Instead I went with this approach, which worked better for me:
相反，我采用了这种方法，这对我来说效果更好：
<TextBlock TextWrapping="Wrap">
<Run>The value</Run>
<Run Text="{Binding Path=MyProperty1, Mode=OneWay}" FontWeight="Bold" />
<Run>was invalid. Please enter it with the format... </Run>
<LineBreak/><LineBreak/>
<Run>Here is another value in the program</Run>
<Run Text="{Binding Path=MyProperty2, Mode=OneWay}" FontWeight="Bold" />
</TextBlock>

Use Binding.StringFormat:
<TextBlock Text="{Binding Artist.Fans.Count, StringFormat='Number of Fans: {0}'}"/>

Here the binding value(clouds.all) is added with "%". You can add any value you want after "\{0\}".
这里绑定值（clouds.all）添加了“%”。您可以在“\{0\}”之后添加您想要的任何值。
<TextBlock Text="{Binding Path=clouds.all, StringFormat=\{0\}%}"/>

With XAML using Template 10 and MVVM:
使用模板 10 和 MVVM 的 XAML：
Just to be clear:
只是要清楚：
- By definition, binding binds values to properties of controls.
- Under the MVVM paradigm as implemented in the 'Template 10' framework, the values are initialized in the ViewModel associated to the relevant XAML page.
- 根据定义，绑定将值绑定到控件的属性。
- 在“模板 10”框架中实现的 MVVM 范式下，值在与相关 XAML 页面关联的 ViewModel 中初始化。
Here is how to have hardcoded text together with a binding in a Text property:
以下是如何将硬编码文本与 Text 属性中的绑定一起使用：
<Page
...
xmlns:vm="using:doubleirish.ViewModels"
xmlns:sys="using:System"
xmlns:controls="using:Template10.Controls"
...
<Page.DataContext>
<vm:StocksViewModel x:Name="ViewModel" />
</Page.DataContext>
...
<controls:PageHeader ... Text="{x:Bind sys:String.Format('Ticker : {0}', ViewModel.Ticker)}">
...
</Page>
