Question

We are using global styles definitions for most of the types. We define then in the app.xaml file. When using TextBlock it is a problem to define a foreground color because it changes all the controls using TextBlock (Button s content color for example). How can we define a global style which will act only on specific TextBlock usages?

目前存在的问题使用:

<Style TargetType={x:Type TextBlock}>
  <Setter Property="Foreground" Value="Red"/>
</Style>

Answer 1

由于我不认为有办法区分“your”(>TextBlock和其他控制的一部分,你的选择非常有限。

You could create named Style and add Style="{StaticResource coloredTextBlock}" or Foreground="{StaticResource textBlockColor}" to all TextBlocks. This would be quite tedious and non-DRY.
You could create your own type that inherits from TextBlock and style that. This has some of the disadvantages of the above solution (you have to remember doing that). But it has much less repetition.

这是因为:Content Presenter为显示内容创造了一个文本Block,而且由于文本Block在视觉树中,它将研究应用水平的资源。如果你在申请一级界定了文本Block的风格,则将适用于控制范围内的这些文本Block。

一项工作是界定<代码>DataTemplate>>,用于<代码>System.String,其中我们可以明确使用默认文本Block显示内容。你可以把该数据模板放在同一个词典中,你界定了文本Block风格,以便这一数据模板将适用于你风格的任何内容。

在你的申请资源中加上这一点,它应当为你工作——

<DataTemplate DataType="{x:Type system:String}">
  <TextBlock Text="{Binding}">
    <TextBlock.Resources>
      <Style TargetType="{x:Type TextBlock}"/>
    </TextBlock.Resources>
  </TextBlock>
</DataTemplate>

如果尚未申报,可在您的xaml中申报一个名称空间,

xmlns:system="clr-namespace:System;assembly=mscorlib"

<Style TargetType="{x:Type TextBlock}">
   <Setter Property="Foreground" Value="Red"/>
</Style>

<DataTemplate DataType="{x:Type system:String}">
  <TextBlock Text="{Binding}">
     <TextBlock.Resources>
        <Style TargetType="{x:Type TextBlock}"/>
     </TextBlock.Resources>
  </TextBlock>
</DataTemplate>

<Style TargetType="{x:Type Button}">
  <Setter Property="Foreground" Value="Yellow"/>
</Style>

<Style TargetType="{x:Type Label}">
  <Setter Property="Foreground" Value="Blue"/>
</Style>

Answer 3

仅举一,:如:

<Style x:Key="stRedTextBlock" TargetType={x:Type TextBlock}>
        <Setter Property="Foreground" Value="Red"/>
</Style>

并提及文本Block控制风格中的关键,在这种方式中,你一直要求这种特定文本Block风格,例如:

<TextBlock Name="textBlock1" Style="{StaticResource stRedTextBlock}" />
