，我使用它們像這樣：
<telerik:RadButton x:Name="rbCancel"
MinWidth="48" MinHeight="48"
Style="{DynamicResource ResourceKey=cancelButtonStyle}"/>
我打開我的對話是這樣的：
wpfMaintenanceInspectionType wnd = new wpfMaintenanceInspectionType();
wnd.WindowStartupLocation = System.Windows.WindowStartupLocation.CenterScreen;
wnd.ShowDialog();
wnd = null;
於是，我第一次顯示對話框，一切正常，但下一次，pathButtonStyle不再工作。當我啓用，鼠標在按鈕上，什麼都沒有發生
我的代碼有什麼問題？
---更新1 ---
如果我把風格在ResourceDictionary中的文件（ButtonStyles.xaml），並在他的構造函數添加到我的對話，每一個工作。
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);
爲什麼它不適用於app.xaml中定義的樣式？
---更新2 --- 的對話是從基類appClass:CBIBaseRadWindow 和基類從RadWindow public partial class CBIBaseRadWindow : RadWindow
--- UPDATE 3 --- 我嘗試新的東西繼承建：我創建了一個新的對話框，只有一個按鈕，點擊按鈕可以創建這個新對話框的新實例。結果：
在啓動，一審做工精良，形象出現，並觸發（IsPressed，IsMouseOver）做工精良 當我點擊按鈕，會出現一個新的對話框，其中包括圖像，但： - 的在第一種情況下的圖像消失 - - 第一個實例觸發器適用於二審（如果我按了一審按鈕，在第二實例的顏色變化）
觸發器不此對話框 上工作
這就像風格不能應用於多個實例？
---更新4 --- Internals of Dependency Property in WPF 在閱讀本文後，我認爲問題是我的依賴屬性。它們在全球的風格定義：
<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>
的，因爲這和，也許，一旦創建了第二個實例，第一丟了東西。
有人可以確認/體弱嗎？
感謝
我有靜態和動態測試，但我已經有兩個情況相同的問題。 – sylvain
