设置 WPF UserControl 的样式

Setting the style of a WPF UserControl

提问by TheLethalCoder

I know I can set the style of a UserControllike so in the control by adding an attribute:

我知道我可以UserControl通过添加一个属性在控件中设置类似的样式：

Style="{StaticResource MyStyle}"

And having a style in my ResourceDictionarythat looks something like the following:

并且在我的样式中具有如下所示的样式ResourceDictionary：

<Style x:Key="MyStyle" TargetType="{x:Type UserControl}">
    <Style.Resources>
        <Style TargetType="Label">
            <!-- Label Setters -->
        </Style>
        <Style TargetType="TextBox">
            <!-- TextBox Setters -->
        </Style>
    </Style.Resources>
</Style>

But is there a way I can set the style of the UserControlin the ResourceDictionarydirectly like:

但是有没有一种方法可以直接设置UserControlin 的样式，ResourceDictionary例如：

<Style x:Key="MyStyle" TargetType="{x:Type MyControl}">

Essentially my question is, can I apply the style directly to the control instead of to the controls components?

基本上我的问题是，我可以将样式直接应用于控件而不是控件组件吗？

EDIT:What I am trying to accomplish is something like the following:

编辑：我想要完成的事情如下：

<Style x:Key="MyStyle" TargetType="{x:Type MyControl}">
    <Setter Property="Background" Value="Black"/>
</Style>
<Style x:Key="{x:Type MyControl}" TargetType="{x:Type MyControl}" BasedOn="{StaticResource MyStyle}"/>

Where the second line applies the style to all controls in the application, if you do something similar with a normal control this approach works.

第二行将样式应用于应用程序中的所有控件，如果您对普通控件执行类似操作，则此方法有效。

However this only sets the Backgroundof the UserControl, so how can I apply that same background to its components.

然而，这只是设置Background的UserControl，我怎么能适用相同的背景及其组件。

How can I do it with the UserControl?

我该怎么做UserControl？

You need to remove the x:Keyfrom your defined style so that it can be applied universally to all controls of the same type as what is defined in the TargetType.

您需要x:Key从定义的样式中删除 ，以便它可以普遍应用于与TargetType.

To quote from MSDN for Style.TargetType Property:

从 MSDN 引用Style.TargetType 属性：

Setting the TargetType property to the TextBlock type without setting an x:Key implicitly sets the x:Key to {x:Type TextBlock}. This also means that if you give the [...] Style an x:Key value of anything other than {x:Type TextBlock}, the Style would not be applied to all TextBlock elements automatically. Instead, you need to apply the style to the TextBlock elements explicitly.

将 TargetType 属性设置为 TextBlock 类型而不设置 x:Key 将 x:Key 隐式设置为 {x:Type TextBlock}。这也意味着如果你给 [...] 样式一个 x:Key 值而不是 {x:Type TextBlock}，样式将不会自动应用于所有 TextBlock 元素。相反，您需要将样式显式应用于 TextBlock 元素。

You can directly set the UserControl's Style like this:

您可以像这样直接设置 UserControl 的样式：

<UserControl x:Class="MyNamespace.MyControl" xmlns:local="MyNamespace" ...>
    <UserControl.Style>
        <Style>
            <Setter Property="local:MyControl.MyProperty" Value="..."/>
            ...
        </Style>
    </UserControl.Style>
</UserControl>

or like this:

或者像这样：

<UserControl x:Class="MyNamespace.MyControl" xmlns:local="MyNamespace" ...>
    <UserControl.Style>
        <Style TargetType="local:MyControl">
            <Setter Property="MyProperty" Value="..."/>
            ...
        </Style>
    </UserControl.Style>
</UserControl>

A default Style in the UserControl's Resources should also work:

UserControl 资源中的默认样式也应该有效：

<UserControl x:Class="MyNamespace.MyControl" xmlns:local="MyNamespace" ...>
    <UserControl.Resources>
        <Style TargetType="local:MyControl">
            <Setter Property="MyProperty" Value="..."/>
            ...
        </Style>
    </UserControl.Resources>
</UserControl>

in your user control xaml place the style inside the resources tag:

在您的用户控件 xaml 中，将样式放置在资源标签内：

<UserControl>
    <UserControl.Resources>
       <Style ...</Style>
    </UserControl.Resources>

    //.. my other components
</UserControl>

To style all controls, add your ResourceDictionary to the resources of your App.xaml.

要设置所有控件的样式，请将您的 ResourceDictionary 添加到 App.xaml 的资源中。

<Application.Resources>
 <!-- Your Resources for the whole application here -->
</Application.Resources>

If your open your Mainwindow with the App...

如果您使用应用程序打开主窗口...

<Application ...
MainWindow="MainWindow">

or during the startup event...

或在启动事件期间...

<Application ...
MainWindow="MainWindow">
Startup="Application_Startup">

the resources are available in every control of your MainWindow.

资源在 MainWindow 的每个控件中都可用。
