如何更改未选定的数据透视表标题的颜色？

Question

我想做的是更改未选择的数据透视表标题的颜色。我总是在 WP7 Silverlight 应用程序中使用 Blend 进行样式设计，现在当我查看 XAML 时，我不知道发生了什么。 我在遵循 PivotStyle 方面需要很少的帮助：

<Style x:Key="PivotStyle" TargetType="controls:Pivot">
            <Setter Property="Margin" Value="0"/>
            <Setter Property="Padding" Value="0"/>
            <Setter Property="Foreground" Value="{StaticResource PhoneForegroundBrush}"/>
            <Setter Property="Background" Value="Transparent"/>
            <Setter Property="ItemsPanel">
                <Setter.Value>
                    <ItemsPanelTemplate>
                        <Grid/>
                    </ItemsPanelTemplate>
                </Setter.Value>
            </Setter>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="controls:Pivot">
                        <Grid HorizontalAlignment="{TemplateBinding HorizontalAlignment}" VerticalAlignment="{TemplateBinding VerticalAlignment}">
                            <Grid.RowDefinitions>
                                <RowDefinition Height="Auto"/>
                                <RowDefinition Height="Auto"/>
                                <RowDefinition Height="*"/>
                            </Grid.RowDefinitions>
                            <Grid Background="{TemplateBinding Background}" CacheMode="BitmapCache" Grid.RowSpan="3"/>
                            <ContentPresenter ContentTemplate="{TemplateBinding TitleTemplate}" Content="{TemplateBinding Title}" Margin="24,17,0,-7"/>

                            <controlsPrimitives:PivotHeadersControl Grid.Row="1"  x:Name="HeadersListElement" FontSize="{StaticResource PhoneFontSizeExtraExtraLarge}" FontFamily="{StaticResource PhoneFontFamilySemiLight}">
                                <controlsPrimitives:PivotHeadersControl.ItemContainerStyle>
                                    <Style TargetType="controlsPrimitives:PivotHeaderItem">
                                        <Setter Property="Template">
                                            <Setter.Value>
                                                <ControlTemplate TargetType="controlsPrimitives:PivotHeaderItem">
                                                    <Grid>
                                                        <VisualStateManager.VisualStateGroups>
                                                            <VisualStateGroup x:Name="SelectionStates">
                                                                <VisualState x:Name="Unselected"/>
                                                                <VisualState x:Name="Selected">
                                                                    <Storyboard>
                                                                        <DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="contentPresenter"/>
                                                                    </Storyboard>
                                                                </VisualState>
                                                            </VisualStateGroup>
                                                        </VisualStateManager.VisualStateGroups>
                                                        <ContentPresenter                                                             
                                                            x:Name="contentPresenter" 
                                                            Content="{TemplateBinding Content}"                                                                                                 
                                                            Opacity="1"

                            </controlsPrimitives:PivotHeadersControl>

                            <ItemsPresenter x:Name="PivotItemPresenter" Margin="{TemplateBinding Padding}" Grid.Row="2"/>

您需要为“选定”或“未选定”状态设置不同的 VisualState。
