WPF 选项卡控件样式

Question

我的用户界面具有相当标准的外观和感觉。它的左侧有一列图标，单击时会在右侧打开一个不同的用户控件。目前，我对选择图标和用户控件包含使用单独的控件。我遇到了奇怪的焦点问题，我厌倦了尝试缓解这些问题，并且想知道是否可以将选项卡控件设计为看起来像我的 UI（假设选项卡控件在导航选项卡时不会出现焦点问题）。

这是基本 UI 的屏幕截图。样式主要是关于如何使选项卡控件页面选择看起来像我的图标列。有人想知道我如何使用选项卡控件来实现这一点吗？我的 xaml 此时非常弱。

<TabControl TabStripPlacement="Left">
    ...
</TabControl>

然后将图标放在 TabItems 的 Header 属性中，将 UserControls 放在 Content 属性中。这将使你达到目标的一半。如果您想要完全相同的外观，则需要通过复制当前模板（使用 Blend 或 ShowMeTheTemplate< /a> 复制当前模板）并根据需要进行修改。但只需更改这些属性即可让您测试 TabControl 是否消除了焦点问题。

编辑：这是一个示例模板，应该与您的屏幕截图非常接近

<Style TargetType="{x:Type TabItem}">
    <Setter Property="Background" Value="Transparent" />

    <Setter Property="Template">
        <Setter.Value>

                        <Setter Property="TextElement.Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}" />
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

它基本上是普通 TabControl 的副本，添加和删除了一些边框。希望有帮助。

如何使用 DockPanel 模板化 TabControl，并将 TabPanel 的 DockPanel.Dock 属性绑定到原始内容TabStripPlacement 属性如图所示？

<Style  TargetType="{x:Type TabControl}" >
    <Setter Property="OverridesDefaultStyle" Value="True" />
    <Setter Property="SnapsToDevicePixels" Value="True" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type TabControl}">
                <DockPanel KeyboardNavigation.TabNavigation="Local" LastChildFill="True">
                    <TabPanel DockPanel.Dock="{TemplateBinding TabStripPlacement}"
                        Name="HeaderPanel"
                        Grid.Row="0"
                        Panel.ZIndex="1" 
                        Margin="0,0,4,1"

                        BorderThickness="1" 
                        CornerRadius="2" >

            </ControlTemplate>
        </Setter.Value>
