我有以下内容TabItem（通过说“TabItem”，我实际上是指激活选项卡的按钮）：

<TabItem RequestBringIntoView="activateTab_Click" Name="tabImplantation" Width="270" Height="138" BorderBrush="{x:Null}" IsEnabled="False" Foreground="#FF075C81">
    <TabItem.Header>
        <StackPanel Orientation="Horizontal">
            <Image Width="148"  Margin="-5,0,0,0" VerticalAlignment="Stretch" Name="implantation_pic" Source="/project;component/Images/implantation_a.jpg" />
        </StackPanel>
    </TabItem.Header>
    ...
</TabItem>

如您所见，它是一个自定义对象，其中TabItem包含一个Image对象。我已经通过设置删除了边框，BorderBrush="{x:Null}"效果很好。

但是，如果它被禁用（IsEnabled="False"），它会呈现某种内部浮雕阴影或类似的东西（也可能是边框，我不确定）。

如果它被禁用，如何在没有这个边框的情况下渲染它？另请参阅下面的图片。提前致谢！

请注意，我不是 ac# 专家，我只是在做一些重新设计。程序本身的开发是外包的。

要获得您想要的外观，您必须编辑TabItem's ControlTemplate（使用 Blend 很容易做到这一点）。

当控件被禁用时，没有呈现“内部浮雕阴影”，它可能是边框效果。这是在（将其添加到您的或）ControlTemplate时禁用该边框的编辑版本：IsEnabled = falseWindow.ResourcesApplication.Resources

这是应用样式更改后控件的外观（在 Blend + SketchFlow for VS2012 中预览）：
