我这样消费它们：
<telerik:RadButton x:Name="rbCancel"
MinWidth="48" MinHeight="48"
Style="{DynamicResource ResourceKey=cancelButtonStyle}"/>
我这样打开对话框：
wpfMaintenanceInspectionType wnd = new wpfMaintenanceInspectionType();
wnd.WindowStartupLocation = System.Windows.WindowStartupLocation.CenterScreen;
wnd.ShowDialog();
wnd = null;
所以，我第一次显示对话框时，一切都很好，但下一次，pathButtonStyle不再工作。当我启用时，鼠标悬停在按钮上，不会发生任何事情
我的代码出了什么问题？
---更新1-
如果我将样式放在ResourceDictionary文件（ButtonStyles.xaml）中，并将其添加到他的ctor中的对话框中，那么每一个都可以很好地工作。
ResourceDictionary dic = new ResourceDictionary();
Uri u = new Uri("pack://application:,,,/BuildingInspector;component/Resources/ButtonStyles.xaml", UriKind.Absolute);
dic.Source = u;
this.Resources.MergedDictionaries.Add(dic);
为什么它不适用于app.xaml中定义的样式？
---更新2---对话框是从基类appClass:CBIBaseRadWindow构建的基类继承自RadWindow public partial class CBIBaseRadWindow : RadWindow
---更新3---我尝试了一件新的事情：我创建了一个新的对话框，只有一个按钮，点击按钮就会创建这个新对话框的新实例。结果：
一开始，第一个实例运行良好，图像出现，触发器（IsPressed、IsMouseOver）运行良好我一点击按钮，就会出现一个带有图像的新对话框，但是：-触发器对此对话框无效-第一个实例上的图像消失-第一个实例上的触发器应用于第二个实例（如果我按下第一个实例的按钮，第二个例子上的颜色变化）
这就好像该样式无法应用于多个实例？？
---更新4---WPF中依赖属性的内部看完这篇文章后，我认为问题出在我的依赖属性上。它们以全局风格定义：
<Style x:Key="cancelButtonStyle"
BasedOn="{StaticResource ResourceKey=defaultButtonStyle}"
TargetType="{x:Type telerik:RadButton}">
<Setter Property="app:DependencyProperties.ImagePath" Value="{DynamicResource ResourceKey=pathCancel}" />
<Setter Property="app:DependencyProperties.Color" Value="Salmon" />
<Setter Property="app:DependencyProperties.MouseOverColor" Value="SandyBrown" />
<Setter Property="app:DependencyProperties.PressedColor" Value="Red" />
</Style>
正因为如此，也许第二个实例一创建，第一个实例就失去了一些东西。
有人能证实吗？
感谢
我认为您不想在取消按钮样式中使用DynamicResource。将DynamicResource更改为StaticResource。
看看这个堆栈溢出问题，了解更多信息：
什么'；WPF中StaticResource和DynamicResource之间的区别是什么？
