在应用程序资源中定义的使用样式

我在使用其他类中的应用程序资源中定义的任何样式时遇到问题。这些是我的App.xaml类的内容。当我尝试应用TextBox类，我得到错误：无法找到指定的资源“validationTextboxStyle”在应用程序资源中定义的使用样式

<Application x:Class="ClientApp.App" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     xmlns:extToolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit/extended" 
     StartupUri="LoginWindow.xaml"> 
<Application.Resources> 
    <Style x:Key="validationTextboxStyle" TargetType="TextBox"> 
     <Setter Property="Validation.ErrorTemplate"> 
      <Setter.Value> 
       <ControlTemplate> 
        <DockPanel LastChildFill="True"> 
         <TextBlock DockPanel.Dock="Right" 
        Foreground="Orange" 
        FontSize="12pt"> 
        !!!! 
         </TextBlock> 
         <Border BorderBrush="Green" BorderThickness="1"> 
          <AdornedElementPlaceholder /> 
         </Border> 
        </DockPanel> 
       </ControlTemplate> 
      </Setter.Value> 
     </Setter> 
    </Style> 


</Application.Resources> 
<Application.MainWindow> 
    <NavigationWindow Source="Main.xaml"></NavigationWindow> 
</Application.MainWindow>

我尝试使用的样式在另一个窗口。

“其他窗口”是如何创建的？你可能想要放置一个断点并检查它是否是“资源”。 – 2012-03-05 18:07:16

当我尝试调试时，我会注意什么？我试过Window.Resources但不存在。 – Aaron 2012-03-05 18:25:36

在C＃中，做一个'var rez = this.Resources; [断点] GC.KeepAlive（REZ）;'。它存在，但它隐藏在'FrameworkElement'显示中。 – 2012-03-05 18:46:04

如果你在你的应用程序类的构造函数，请确保您还添加在App.xaml中定义的InitializeComponent(); 否则它不会加载资源。
