如何在 XAML 中调用 ResourceDictionary 文件中的样式?
How to call a Style in a ResourceDictionary file in XAML?
我在创建的 style.xaml
ResourceDictionary
文件中有一个按钮样式。
我用这段代码来调用它:
<Button Style="{DynamicResource exitButton}" />
但它无法识别样式键,或者使用 StaticResource 也不起作用。如何解决这个问题?
我的风格代码:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style x:Key="exitButton" TargetType="Button">
<Setter Property="Width" Value="22"/>
<Setter Property="Height" Value="32"/>
<Setter Property="Background" Value="#FF7070"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border Width="{TemplateBinding Width}"
Height="{TemplateBinding Height}"
HorizontalAlignment="Center"
VerticalAlignment="Center">
<TextBlock Text="X"
FontSize="15"
Foreground="White"
FontWeight="Bold"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
您必须在 xaml 的 Resources
标签中导入 ResourceDictionary
文件。
像这样:
<UserControl blablabla...>
<UserControl.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/*PROJECT_NAME*;component/*FOLDER_PATH*/style.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</USerControl.Resources>
<!-- the content -->
...
<Button Style="{StaticResource exitButton}"/>
</UserControl>
您有两个选择:
- 正如 HasNotifications 所说,将资源嵌入到您希望样式生效的视图中
- 将样式嵌入应用程序 ResourceDictionary。在这种情况下,该样式将可用于应用程序上的任何视图
Add the following code to the App.xaml file:
<Application x:Class="WpfApp1.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApp1"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/*PROJECT_NAME*;component/*FOLDER_PATH*/style.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
