如何在 Windows Phone 8 中更改数据透视表头模板

Question

我希望能够在 Windows Phone 8 中更改 Pivot Headers 和 Application Title 的背景。据我所知，我必须创建一个针对 Pivot 控件的自定义样式。但是，我不确定是否只更改标题的背景？

我想以某种方式调整样式

<Style x:Key="MyPivotStyle" TargetType="phone:Pivot">
<Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="phone:Pivot">
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition Height="Auto"/>
                    <RowDefinition Height="Auto"/>
                    <RowDefinition Height="*"/>
                </Grid.RowDefinitions>
                <Grid CacheMode="BitmapCache" Grid.RowSpan="2">
                    <Grid.Background>
                        <ImageBrush ImageSource="/Assets/bg_header.png"/>
                    </Grid.Background>
                </Grid>
                <Grid Background="{TemplateBinding Background}" CacheMode="BitmapCache" Grid.Row="2" />
                <ContentPresenter ContentTemplate="{TemplateBinding TitleTemplate}" Margin="24,17,0,-7">
                    <StackPanel Orientation="Horizontal">
                        <Image Source="/Assets/company_name.png" Width="213.75" HorizontalAlignment="Left" VerticalAlignment="Top" />
                        <Button HorizontalAlignment="Right" VerticalAlignment="Top" Margin="140,-20,0,35" BorderThickness="0" x:Name="btnHome">
                            <Image Source="/Assets/btnHome.png" Width="48" Height="48" ></Image>
                        </Button>
                    </StackPanel>
                </ContentPresenter>
                <controlsPrimitives:PivotHeadersControl x:Name="HeadersListElement" Foreground="White"  Grid.Row="1"/>
                <ItemsPresenter x:Name="PivotItemPresenter" Margin="{TemplateBinding Padding}" Grid.Row="2"/>
            </Grid>
        </ControlTemplate>
    </Setter.Value>
</Setter>

为 WinRT 编辑（抱歉延迟，感谢提醒更新此答案）： 要编辑完整模板，请在 Document Outline 中右键单击控件并选择 Edit Template - Current (in Visual Studio or Blend)，然后将为您生成模板，您可以根据需要进行编辑，see my answer here for screenshots.

以下是针对 Windows Phone Windows 运行时重做的两个示例（发布于 2013 年）：

<Grid Background="Transparent">
    <Pivot Title="Re-templating example">
        <Pivot.HeaderTemplate>
            <DataTemplate>
                <Grid Background="Blue">
                    <TextBlock Text="{Binding}" />
                </Grid>
            </DataTemplate>
        </Pivot.HeaderTemplate>
        <Pivot.TitleTemplate>
            <DataTemplate>
                <Grid Background="Green">
                    <TextBlock Text="{Binding}" />
                </Grid>
            </DataTemplate>
        </Pivot.TitleTemplate>
        <PivotItem Header="One">
            <TextBlock FontSize="35"
                        Text="This is item one" />
        </PivotItem>
        <PivotItem Header="Two">
            <TextBlock FontSize="35"
                        Text="This is item 2" />
        </PivotItem>
    </Pivot>
</Grid>

第二个例子，请注意我们将 ContentPresenter 包装在一个 Grid 中（您也可以使用边框或任何其他元素）：

<Page.Resources>
    <SolidColorBrush x:Key="PivotBackground" Color="#FFE46C08"/>

    <Style x:Key="PivotStyle" TargetType="Pivot">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Pivot">
                    <Grid x:Name="RootElement" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" VerticalAlignment="{TemplateBinding VerticalAlignment}">
                        <Grid.RowDefinitions>
                            <RowDefinition Height="Auto"/>
                            <RowDefinition Height="*"/>
                        </Grid.RowDefinitions>
                        <!--Notice that ContentControl is wrapped in a Grid and Background set to resource furtehr up-->
                        <Grid VerticalAlignment="Center" Background="{StaticResource PivotBackground}">
                            <ContentControl x:Name="TitleContentControl" ContentTemplate="{TemplateBinding TitleTemplate}" Content="{TemplateBinding Title}" Style="{StaticResource PivotTitleContentControlStyle}"/>
                        </Grid>
                        <ScrollViewer x:Name="ScrollViewer" HorizontalSnapPointsAlignment="Center" HorizontalSnapPointsType="MandatorySingle" HorizontalScrollBarVisibility="Hidden" Margin="{TemplateBinding Padding}" Grid.Row="1" Template="{StaticResource ScrollViewerScrollBarlessTemplate}" VerticalSnapPointsType="None" VerticalScrollBarVisibility="Disabled" VerticalScrollMode="Disabled" VerticalContentAlignment="Stretch" ZoomMode="Disabled">
                            <PivotPanel x:Name="Panel" VerticalAlignment="Stretch">
                                <!--Background set to resource further up-->
                                <PivotHeaderPanel Background="{StaticResource PivotBackground}" x:Name="Header" >
                                    <PivotHeaderPanel.RenderTransform>
                                        <CompositeTransform x:Name="HeaderTranslateTransform" TranslateX="0"/>
                                    </PivotHeaderPanel.RenderTransform>
                                </PivotHeaderPanel>
                                <ItemsPresenter x:Name="PivotItemPresenter">
                                    <ItemsPresenter.RenderTransform>
                                        <TranslateTransform x:Name="ItemsPresenterTranslateTransform" X="0"/>
                                    </ItemsPresenter.RenderTransform>
                                </ItemsPresenter>
                            </PivotPanel>
                        </ScrollViewer>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Page.Resources>

使用上面的样式：

<Grid Background="Transparent">
    <Pivot Style="{StaticResource PivotStyle}"
            Title="Re-templating example">
        <PivotItem Header="One">
            <TextBlock FontSize="35" Text="This is item one" />
        </PivotItem>
        <PivotItem Header="Two">
            <TextBlock FontSize="35" Text="This is item 2"/>
        </PivotItem>
    </Pivot>
</Grid>

顺便说一下，通常最好将样式保存在单独的样式文件中——为了简单起见，我只将它们保存在同一页面上。如果删除 x:key 属性，样式将应用于设置目标类型的所有控件（本例中为 Pivot）。

2013 年对 Windows Phone 7.X 和 Windows Phone 8 的回答（WP Silverlight：

有几种方法可以做到这一点，但这里有一个例子：

<Grid x:Name="LayoutRoot" Background="Transparent">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="*"/>  
    </Grid.RowDefinitions>

    <phone:Pivot Grid.Row="1">
        <phone:Pivot.HeaderTemplate>
            <DataTemplate>
                <Grid Background="Red" Height="200">
                    <TextBlock Text="{Binding}"/>
                </Grid>
            </DataTemplate>
        </phone:Pivot.HeaderTemplate>
        <phone:PivotItem Header="Test">
            <TextBlock Text="ghjgb"/>
        </phone:PivotItem>
        <phone:PivotItem Header="Test">
            <TextBlock Text="ghjgb"/>
        </phone:PivotItem>
    </phone:Pivot>

如果你想这样做：

您可以这样做，删除 x:key 以应用到所有枢轴，或使用该键为刚刚选定的枢轴元素设置样式，如下所示：

<controls:Pivot Title="The Marathon Runner" Style="{StaticResource PivotStyle}">
    <Style x:Key="PivotStyle" TargetType="phone: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="phone:Pivot">
                    <Grid HorizontalAlignment="{TemplateBinding HorizontalAlignment}"
      VerticalAlignment="{TemplateBinding VerticalAlignment}">
                        <Grid.RowDefinitions>
                            <RowDefinition Height="Auto"/>
                            <RowDefinition Height="Auto"/>
                            <RowDefinition Height="*"/>
                        </Grid.RowDefinitions>
                        <Grid Background="#ff9000" CacheMode="BitmapCache" Grid.RowSpan="2" />
                        <Grid Background="{TemplateBinding Background}" CacheMode="BitmapCache"
        Grid.Row="2" />
                        <ContentPresenter ContentTemplate="{TemplateBinding TitleTemplate}"
                    Content="{TemplateBinding Title}" Margin="24,17,0,-7"/>
                        <Primitives:PivotHeadersControl x:Name="HeadersListElement"
                                          Grid.Row="1"/>
                        <ItemsPresenter x:Name="PivotItemPresenter"
                  Margin="{TemplateBinding Padding}" Grid.Row="2"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>

别忘了使用：

xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
xmlns:Primitives="clr-namespace:Microsoft.Phone.Controls.Primitives;assembly=Microsoft.Phone"
