將樣式應用到自定義組合框中

我創建了從組合框派生的控件。我的應用程序中每個組合框都有一個共同的樣式。除了我創建的控件外，每個組合框的樣式都可以正常工作。將樣式應用到自定義組合框中

請參考代碼。

-xaml -Code對於自定義組合框

<local:FilteredComboBox Grid.Row="3" Grid.Column="1" Height="20"  x:Name="cbBillingProvider" Padding="4 3" />

自定義組合框--C＃代碼。從combobox.xaml

public class FilteredComboBox : ComboBox 
{ 
}

-Combo框樣式代碼任何一個可以幫助採用同樣的風格，我的自定義組合框？

感謝

試試這個：

public class FilteredComboBox : ComboBox 
{ 
    static FilteredComboBox() 
    { 
     DefaultStyleKeyProperty.OverrideMetadata(typeof(FilteredComboBox), 
      new FrameworkPropertyMetadata(typeof(ComboBox))); 
    } 
}

我得承認我不喜歡這一點，因爲你必須創建一個新的行所創建的每個繼承類型（可能不可能），但您始終可以引用默認樣式。

我想這是一樣硬在C＃每次編碼它
