我在作为 MMC 管理单元一部分的 Windows 窗体内托管 WPF TabControl。在 Windows 8.1 上一切正常：

但我在 Windows Server 2012 R2 中有一个问题：

从上面，你可以看到它增加了我的 TabControl 的边框。此外，我注意到我的其他一些 WPF 选项卡项中的其他问题（例如列表视图项垂直对齐到顶部而不是中心以及类似的东西）。但现在，让我们解决双厚边框问题。为什么会发生这种情况，我该如何解决？我已经尝试谷歌几个小时来解决这个问题，但我似乎找不到任何好的解决方法或修复。另请注意，在 Inbound 文本下，您也可以在此处看到边框。这不是很奇特吗？

为了在 Windows 窗体中托管 WPF 控件，我将ElementHost对话框的对象部分的子控件设置为 WPF 控件：

WPFControlHost.Child = new WPFConfigurationTabPageControl(configuration, this);

在我的 WPF 控件中，我没有做任何特别或不寻常的事情。我在 XAML 中创建我的选项卡控件：

<TabControl Margin="10 10 10 0">
    <TabItem Name="TabItemIdentity" Header="_Identity"/>
    <TabItem Name="TabItemDirectories" Header="_Directories"/>
    <TabItem Name="TabItemRouting" Header="_Routing"/>
    <TabItem Name="TabItemOutbound" Header="O_utbound"/>
    <TabItem Name="TabItemInbound" Header="I_nbound"/>
</TabControl>

然后我在构造函数中为我的 WPF 控件设置选项卡项：

IdentityControl = new WPFIdentityControl(configuration, this);
TabItemIdentity.Content = IdentityControl;
DirectoriesControl = new WPFDirectoriesControl(configuration, this);
TabItemDirectories.Content = DirectoriesControl;
RoutingControl = new WPFRoutingControl(configuration, this);
TabItemRouting.Content = RoutingControl;
OutboundControl = new WPFOutboundControl(configuration, this);
TabItemOutbound.Content = OutboundControl;
InboundControl = new WPFInboundControl(configuration, this);
TabItemInbound.Content = InboundControl;

编辑：当我在 TabControl ( <TabControl Margin="10 10 10 0" BorderThickness="0">) 上设置 0 厚度时，它看起来如下：

因此，可以肯定的是，放大的边框是作为 Windows Server 2012 R2 中控件的一部分以这种方式呈现的TabControl，但这是为什么呢？为什么它们会放大，我该如何解决？

将 BorderThickness 设置为 1 显式解决了放大边框的问题，但不能修复标题模板本身有一个底部边框或标题的底部底部边框是两倍大小的问题，所以我认为我需要启动 Blend 和编辑这些模板手动删除底部边框，这完全是疯狂的。为什么在 Server 2012 上会发生这种情况？

为了修复它，我在 Blend 中编辑了模板。如果您以前从未使用过 Blend for Visual Studio，那么现在有机会开始使用 ( "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Blend\Blend.exe")。我用它来更改 TabItems 的模板。您只需右键单击、编辑模板、编辑副本，它就会包含您需要修改的大部分标记。BorderThickness="0,1,1,1"我更改了很多to的引用BorderThickness="1,1,1,0"。这是标记...

对于我的 TabControl：

<TabControl Margin="10 10 10 0" BorderThickness="1">
    <TabItem Name="TabItemIdentity" Header="_Identity" Style="{DynamicResource TabItemStyle1}"/>
    <TabItem Name="TabItemDirectories" Header="_Directories" Style="{DynamicResource TabItemStyle1}"/>
    <TabItem Name="TabItemRouting" Header="_Routing" Style="{DynamicResource TabItemStyle1}"/>
    <TabItem Name="TabItemOutbound" Header="O_utbound" Style="{DynamicResource TabItemStyle1}"/>
    <TabItem Name="TabItemInbound" Header="I_nbound" Style="{DynamicResource TabItemStyle1}"/>
</TabControl>

噩梦般的。

编辑：在 Windows Server 2008 R2（另一场灾难）上，您需要为控件显式设置背景，因为它不支持透明度，并且在Background="Transparent"为任何控件的样式属性设置时默认为控件的默认表单背景颜色，因此您如果控件未正确呈现（例如，<TabControl Margin="10 10 10 0" BorderThickness="1" Background="White">），则应在控件上将控件背景显式设置为白色。另外，我强烈建议您在 Blend 中为 TabControl 编辑模板并在本地应用它（<TabControl Margin="10 10 10 0" BorderThickness="1" Background="White" Style="{DynamicResource TabControlStyle1}")，所以在这里应用默认模板并将其作为应用程序 DLL 的一部分在本地打包，你应该没问题。出于某种原因，它不会在 Windows Server 2008 R2 中正确呈现模板，除非它是属于同一 DLL 的动态资源。这可能是因为我设置了 COMPLUS_Version 环境变量以使 MMC 与 .NET Framework 4.5 一起工作，而它可能一直在尝试使用来自以前版本的 .NET Framework 的旧模板。
