如何覆盖全局样式(没有 x:Key)，或者将命名样式应用于所有类型定位控件? [英] How to override a global style (that doesn't have an x:Key), or alternatively apply a named style to all type-targeted controls?

问题描述

我声明了一个我想应用于项目中所有按钮的样式，该样式位于 ResourceDictionary 中:

I declared a style that I want to apply to ALL the buttons in the project, the style resides in the ResourceDictionary:

<Style TargetType="StackPanel">
    <Setter Property="Orientation" Value="Horizontal" />
    <Setter Property="VerticalAlignment" Value="Center"/>
    <Setter Property="HorizontalAlignment" Value="Center"/>
</Style>

现在，在某些窗口中，我想继承此样式但添加一个值:

Now, in some window, I want to inherit from this style but add a value:

<Style TargetType="StackPanel"> 
    <Setter Property="Margin" Value="5"/>
</Style>

问题是它没有从全局样式继承，为了继承我必须为全局样式分配一个键:

The problem is that it doesn't inherit from the global style, in order to inherit I have to assign a key to the global style:

<Style TargetType="StackPanel" x:Key="StackPanelStyle" />

然后在窗口的 XAML 中继承(或/和覆盖 - 可选)它:

And then in the window's XAML inherit (or/and override - optional) it:

<Style TargetType="StackPanel" BasedOn="StackPanelStyle" />

问题是如果你分配一个键，它不是全局的，你必须在每个窗口/范围内调用它.

The problem is that if you assign a key, it's not global and you have to call it on each window/scope.

我的问题的解决方案应该是两者之一(还有什么我遗漏的吗?):

A solution to my question should be one of the two (is there anything else I am missing out?):

1. 具有带键的全局样式，该样式会自动应用于整个应用程序中的所有目标控件.
2. 一种引用 ResourceDictionary 级别未命名样式的方法，无需并覆盖它.

我想过在命名样式(在 ResourceDictionary 中)附近重新声明实际有效的样式:

I thought about redeclaring the styles near the named styles (in the ResourceDictionary) which actually works:

<!--In the ResourceDictionary-->
<Style x:Key="StackPanelStyle" TargetType="StackPanel">
    <Setter Property="Orientation" Value="Horizontal" />
    <Setter Property="VerticalAlignment" Value="Center"/>
    <Setter Property="HorizontalAlignment" Value="Center"/>
</Style>
<!--In the app.xaml-->
<Style TargetType="StackPanel" BasedOn="{StaticResource StackPanelStyle}"/>
<!--In the window/page scope-->
<Style TargetType="StackPanel" BasedOn="{StaticResource StackPanelStyle}"/

但我正在寻找比愚蠢地重新声明所有样式更好的东西.

But I am looking for better stuff than stupidly redeclare all the styles.

推荐答案

试试这个:

<Style TargetType="{x:Type StackPanel}" BasedOn="{StaticResource {x:Type StackPanel}}">
  <!-- ... -->
</Style>

我已经在 App.xaml 的 ResourceDictionary 中声明了我的基本样式，如果我在这样的特定窗口中覆盖它们，它通常可以工作.

I have declared my base styles in a ResourceDictionary in App.xaml, if i override them in a specific window like this, it usually works.
