WPF 选项卡控件样式

Question

我的 UI 具有相当标准的外观和感觉。它在左侧有一列图标，单击时在右侧打开不同的用户控件。目前我正在为选择图标和用户控件容器使用单独的控件。我有奇怪的焦点问题，我厌倦了试图缓解，我想知道我是否可以设置一个 tabcontrol 的样式，让它看起来像我的 UI（假设 tabcontrol 在导航选项卡时不会有焦点问题）。

这是基本 UI 的屏幕截图。样式主要是关于如何让 tabcontrols 页面选择看起来像我的图标列。任何人都想把他们的帽子扔在戒指上，我如何用 tabcontrol 完成这个？在这一点上，我的 xaml 很弱。

如何使用DockPanel 模板化TabControl，并将TabPanel 的DockPanel.Dock 属性绑定到原始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" 
                        IsItemsHost="True"
                        KeyboardNavigation.TabIndex="1"
                        Background="Transparent" />
                    <Border 
                        Name="Border" 
                        Background="Transparent" 
                        BorderBrush="Black" 
                        BorderThickness="1" 
                        CornerRadius="2" >
                        <ContentPresenter 
                            ContentSource="SelectedContent" />
                    </Border>
                </DockPanel>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsEnabled" Value="False">
                        <Setter Property="Foreground" Value="Black" />
                        <Setter TargetName="Border" Property="BorderBrush" Value="DarkGray" />
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

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

然后将图标放在 TabItems 的 Header 属性中，并将 UserControls 放在 Content 属性中。这会让你走到一半。如果您想要完全相同的外观，您需要通过复制当前模板（使用 Blend 或 ShowMeTheTemplate 复制当前模板）并根据需要修改它来重新模板 TabControl 和 TabItem。但只需更改这些属性，您就可以测试 TabControl 是否能解决您的焦点问题。

编辑：这是一个与您的屏幕截图非常接近的示例模板

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

    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type TabItem}">

                <Border x:Name="PART_Border" Background="{TemplateBinding Background}" BorderThickness="1" BorderBrush="LightGray" Margin="2">
                    <ContentPresenter ContentSource="Header" Margin="2" />
                </Border>

                <ControlTemplate.Triggers>
                    <Trigger Property="IsSelected" Value="True">
                        <Setter TargetName="PART_Border" Property="BorderBrush" Value="Black" />
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

<Style TargetType="{x:Type TabControl}">
    <Setter Property="TabStripPlacement" Value="Left" />
    <Setter Property="Margin" Value="2" />
    <Setter Property="Padding" Value="2"    />
    <Setter Property="Background" Value="White" />


    <Setter Property="Template">

它基本上是普通 TabControl 的副本，添加和删除了一些边框。希望对您有所帮助。
