Set TextBlock to be entirely bold when DataBound in WPF
提问by robintw
I have a databound TextBlock control (which is being used inside a DataTemplate to display items in a ListBox) and I want to make all the text in the control bold. I can't seem to find a property in the properties explorer to set the whole text to bold, and all I can find online is the use of the <Bold>tag inside the TextBlock, but I can't put that in as the data is coming directly from the data source.
我有一个数据绑定 TextBlock 控件（在 DataTemplate 中使用它来显示 ListBox 中的项目），我想将控件中的所有文本设为粗体。我似乎无法在属性资源管理器中找到将整个文本设置为粗体的属性，而我在网上所能找到的只是<Bold>在 TextBlock 中使用了标记，但是随着数据的到来，我无法将其放入直接来自数据源。
There must be a way to do this - but how? I'm very inexperienced in WPF so I don't really know where to look.
必须有一种方法可以做到这一点 - 但如何呢？我在 WPF 方面非常缺乏经验，所以我真的不知道去哪里找。

Am I missing something, or do you just need to set the FontWeight property to "Bold"?
我是否遗漏了什么，或者您是否只需要将 FontWeight 属性设置为“Bold”？
<TextBlock FontWeight="Bold" Text="{Binding Foo}" />

You say that the data is coming directly from the datasource; is it possible to place a layer of abstraction in front of it? Its quite common to create a View for what you are displaying, and have the View communicate with the data. The most common implementation of this idea is Model View View-Model (MVVM). Have a read about it online.
你说数据直接来自数据源；是否可以在它前面放置一个抽象层？为您正在显示的内容创建一个视图，并让该视图与数据进行通信是很常见的。这个想法最常见的实现是模型视图视图模型（MVVM）。在线阅读有关它的信息。
You might have a 'DisplayText' property that is bound to the textbox, and it is simply a 'getter' that wraps the underlying text. It can detect if the text is already wrapped in and if not, wrap it.
您可能有一个绑定到文本框的“DisplayText”属性，它只是一个包装底层文本的“getter”。它可以检测文本是否已经被换行，如果没有，就换行。
Eg.
例如。
public class TestView {
private Test datasource;
public TestView(Test source)
{
this.datasource = source;
}
public string DisplayText {
get {
if (datasource.Text.Contains("<bold>")==false) {
return "<bold>" + datasource.Text + "</bold>";
}
return datasource.Text;
}
}
}
Then, bind to the View instead of directly to the object.
然后，绑定到视图而不是直接绑定到对象。

Rather than just having a TextBlock, try this:
而不是只有一个 TextBlock，试试这个：
<TextBlock>
<Bold>
<Run />
</Bold>
</TextBlock>
Then databind to the Run.TextProperty instead.
然后将数据绑定到 Run.TextProperty。
