不知道这是否是最简单的方法,但我会修改默认的 TabControl 样式:
<SolidColorBrush x:Key="WindowBackgroundBrush" Color="#FFF" />
<SolidColorBrush x:Key="SolidBorderBrush" Color="#888" />
<SolidColorBrush x:Key="DisabledForegroundBrush" Color="#888" />
<SolidColorBrush x:Key="DisabledBorderBrush" Color="#AAA" />
<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}">
<Grid KeyboardNavigation.TabNavigation="Local">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TabPanel
Name="HeaderPanel"
Grid.Row="0"
Panel.ZIndex="1"
Margin="200,0,4,-1"
IsItemsHost="True"
KeyboardNavigation.TabIndex="1"
Background="Transparent" />
<Border
Name="Border"
Grid.Row="1"
Background="{StaticResource WindowBackgroundBrush}"
BorderBrush="{StaticResource SolidBorderBrush}"
BorderThickness="1"
CornerRadius="2"
KeyboardNavigation.TabNavigation="Local"
KeyboardNavigation.DirectionalNavigation="Contained"
KeyboardNavigation.TabIndex="2" >
<ContentPresenter
Name="PART_SelectedContentHost"
Margin="4"
ContentSource="SelectedContent" />
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Foreground" Value="{StaticResource DisabledForegroundBrush}" />
<Setter TargetName="Border" Property="BorderBrush" Value="{StaticResource DisabledBorderBrush}" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
注意?中TabPanel
元素的 Margin 属性。ContolTemplate
该边距决定了标签的开始位置。默认为 0,0,4,-1,我将其修改为 200,0,4,-1 以符合您的要求。
如果你想知道我是如何制作这种风格的,有几种方法。最简单的方法是使用 Expression Blend。它有一个选项可以“破坏”您的控件并公开它的所有默认部分和样式。另一种方法是在 MSDN 中搜索 ControlTemplates,因为它们是公开的。(我用的是第二种方法)
