Question

我正在使用现有的Pivot标头模板，但它没有给我我需要的效果。我需要当前选择的PivotItem具有蓝色前景和白色背景，而所有其他枢轴项目具有标准禁用前景和背景外观。目前下面我有我认为除了选定的数据透视表面上的蓝色前景之外的一切，但我无法弄清楚如何正确地将前景应用于所选项目？

将<ContentPresenter>更改为<TextBlock>

喜欢这样

<Style x:Key="PivotHeaderItemStyle1" TargetType="Primitives:PivotHeaderItem">
    <Setter Property="Background" Value="Transparent"/>
    <Setter Property="Padding" Value="10,0,10,0"/>
    <Setter Property="Margin" Value="0"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Primitives:PivotHeaderItem">
                <Grid>
                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="SelectionStates">
                            <VisualState x:Name="Unselected">
                                <Storyboard>
                                    <ColorAnimation Duration="0" Storyboard.TargetName="border_highlight" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)" To="Transparent"/>
                                    <ColorAnimation  Duration="0" Storyboard.TargetName="contentPresenter" Storyboard.TargetProperty="(TextBlock.Foreground).(SolidColorBrush.Color)" To="Green"/>
                                </Storyboard>
                            </VisualState>
                            <VisualState x:Name="Selected">
                                <Storyboard>
                                    <ColorAnimation  Duration="0:0:1" Storyboard.TargetName="border_highlight" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)" To="PaleGreen"/>
                                    <DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="contentPresenter"/>
                                    <ColorAnimation  Duration="0" Storyboard.TargetName="contentPresenter" Storyboard.TargetProperty="(TextBlock.Foreground).(SolidColorBrush.Color)" To="Blue"/>
                                </Storyboard>
                            </VisualState>
                        </VisualStateGroup>
                    </VisualStateManager.VisualStateGroups>
                    <Border x:Name="border_highlight" Background="{TemplateBinding Background}" >
                        <!--<ContentPresenter x:Name="contentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" Opacity="{StaticResource PhonePivotUnselectedItemOpacity}"/>-->
                        <TextBlock x:Name="contentPresenter" Foreground="{TemplateBinding Foreground}" Text="{TemplateBinding Content}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" Opacity="{StaticResource PhonePivotUnselectedItemOpacity}"></TextBlock>
                    </Border>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

然后你可以为Foreground设置动画。这是上面代码的屏幕截图。选择颜色=蓝色和未选择颜色=绿色。您需要在背景动画中添加回来。

@Teysz，我认为对于Windows 10 UWP，您最好从PivotItemHeader的默认样式开始，并在XAML文件的..Resources部分中复制它。 Visual Studio 2015无法插入默认样式，因此您必须自己从以下位置获取： %ProgramFiles(x86)%\Windows Kits\10\DesignTime\CommonConfiguration\Neutral\UAP\10.0.10240.0\Generic\generic.xaml 我在http://blog.hompus.nl/2015/09/04/responsive-pivot-headers-in-universal-windows-platform-apps/
