Wpf風格適用於設計師，但不適用於運行時

Question

我有三個xaml文件。

1. Button.xaml（按鈕樣式）
2. Default.xaml（主題文件）（包括按鈕梅傑斯資源文件）
3. MainWindo.xaml（使用default.xaml資源字典）。

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" 
        xmlns:primatives="clr-namespace:System.Windows.Controls;assembly=PresentationFramework"> 

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

</ResourceDictionary> 

MainWindow.xaml：

<Window x:Class="RemoteDesktop.GUI.MainWindow" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

          </Setter.Value> 
         </Setter> 


        </Style> 
       </Button.Style>--> 

      </Button> 
     </Grid> 
    </Border> 
</Window> 

在上面的窗口按鈕樣式在設計時應用，但運行時會重置爲默認狀態。

Answer 1

，我看你有沒有

rootdirectory \控件\ button.xaml

rootdirectory \主題\默認\ default.xaml

rootdirectory \ mainwindow.xaml

所以這裏是東西

在default.xaml你必須去後面的目錄訪問你的按鈕控件像這樣

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