ResourceDictionary 中的 Windows 样式不适用 [英] Windows Style from ResourceDictionary don't apply

问题描述

由于我的应用程序中有多个 Window，我正在寻找一种不需要我在每个 Windowbinding 的解决方案代码>.

As I have multiple Windows in my application, I am looking for a solution that does not require me to set a binding on each Window.

我创建了一个 ResourceDictionary，它有一个 style 用于窗口背景:

I created a ResourceDictionary which has a style for the Window Background:

<Style TargetType="{x:Type Window}">
    <Setter Property="Background" Value="AliceBlue"/>
</Style>

在我的 XAML 中，我设置了 ResourceDictionary:

In my XAML, I set the ResourceDictionary:

<Window.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Templates.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Window.Resources>

没有错误，但我的 Window 颜色保持白色.

There is no error, but my Window color stays white.

推荐答案

在资源字典中添加新画笔

Add a new brush in your resource dictionary

<SolidColorBrush x:Key="WindowBackground" Color="AliceBlue" />

并在您的 WPF 窗口中简单地将所需资源设置为窗口背景属性

and in your WPF window simply set the required resource to the window background property

<Window x:Class="GDD.Presentation.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="300" Width="300"
    Background="{StaticResource WindowBackground}">
