刪除右鍵單擊事件的ListBoxItem背景

Question

我已經設法防止在懸停和選擇時顯示ListBox項目背景，但是，當我右鍵單擊某個項目時，即使在ListBox再次對焦時顯示懸停時的背景（對於先前右鍵單擊的元素）。

我不能在ListBoxPreviewMouseDown中使用e.Handled = true，因爲這會打破我的右鍵單擊上下文菜單。通過中斷，我的意思是它可以防止菜單項對點擊作出反應。上下文菜單顯示正常，但無法調用項目點擊。

我錯過了什麼，還包括ListBoxItem背景不顯示右鍵單擊？

謝謝。

就總是ListBox的ItemContainerStyle屬性設置爲自定義樣式，即不設置它在Style內觸發：

<ListBox Name="ListBoxOne"> 
    <ListBox.Style> 
     <Style TargetType="ListBox"> 
      <Setter Property="ItemContainerStyle" Value="{StaticResource MyListBoxItemStyle}"/> 
     </Style> 
    </ListBox.Style> 
</ListBox>
