你想要的項目的背景顏色是透明的？或者項目和列表框背景 – TerrorAustralis 2010-10-19 22:01:37

不，項目不應該是透明的 – Mediator 2010-10-19 22:06:26

在你的控制模板，你有一個聲明說

<Border ... Background="#FFFFFFFF">...

因爲這並不inherrit風格的背景，你是硬編碼爲您的列表框的背景。

嘗試改變，要Background={TemplateBinding Background}

注：

它在列表框的默認樣式...完整的語句是

<Border BorderThickness="{TemplateBinding BorderThickness}" Background="#FFFFFFFF" BorderBrush="{TemplateBinding BorderBrush}" CornerRadius="2"> 
    <ScrollViewer Template="{StaticResource ScrollViewerControlTemplate1}" Margin="1" Focusable="false" Background="Transparent"> 
     <WrapPanel Margin="2" IsItemsHost="True" /> 
    </ScrollViewer> 
</Border>

它只是不默認樣式 – Mediator 2010-10-19 22:13:24

已編輯的答案我認爲問題在於你的默認樣式 – TerrorAustralis 2010-10-19 22:21:50

tip top =）very well =）謝謝 – Mediator 2010-10-19 22:24:19
