Question

我有三个xaml文件。

Button.xaml（按钮样式）
Default.xaml（主题文件）（包括按钮的合并资源文件）
MainWindo.xaml（使用default.xaml资源字典）。

Button.xaml：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

<ControlTemplate x:Key="ButtonControlTemplate" TargetType="Button">
    <Border Name="Back" >
        <Border.Background>
            <ImageBrush ImageSource="..\Images\ButtonBackground.png" />
        </Border.Background>
        <TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" />
    </Border>
    <ControlTemplate.Triggers>
        <Trigger Property="IsMouseOver" Value="True">
            <Setter TargetName="Back" Property="Effect">
                <Setter.Value>
                    <DropShadowEffect ShadowDepth="0" Direction="0"               
                                             BlurRadius="15"Color="#D3F80A" Opacity="1"/>
                </Setter.Value>
            </Setter>
        </Trigger>
    </ControlTemplate.Triggers>
</ControlTemplate>

<Style TargetType="{x:Type Button}">
    <Setter Property="Template" Value="{StaticResource ButtonControlTemplate}" />
</Style>

 </ResourceDictionary>

Default.xaml：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="Controls\Button.xaml"></ResourceDictionary>
    </ResourceDictionary.MergedDictionaries>

</ResourceDictionary>

MainWindow.xaml：

上面的窗口按钮样式在设计时应用，但运行时它会重置为默认状态。

Answer 1

因为我看到你有

rootdirectory \ controls \ button.xaml

rootdirectory \主题\默认\ default.xaml

rootdirectory \ mainwindow.xaml

所以这是事物

在default.xaml中，您必须转到后面的目录才能像这样访问您的按钮控件

<ResourceDictionary Source="..\..\Controls\Button.xaml"></ResourceDictionary>

Wpf样式应用于设计器但不在运行时应用
