Question

我一直在试图在代码和Blend中改变LoopingSelector周围的红色边框。我只是想不出怎么做。这是一张图片，让您了解我在说什么。

enter image description here

    <Grid Grid.Row="1" Margin="12,0,12,0" toolkit:TurnstileFeatherEffect.FeatheringIndex="1">
        <Grid.Resources>
            <DataTemplate x:Key="KiloTemplate">
                <Grid Background="DarkBlue">
                    <TextBlock Text="{Binding}" FontSize="54" FontFamily="{StaticResource PhoneFontFamilySemiBold}" HorizontalAlignment="Center" VerticalAlignment="Center" />
                    <TextBlock Text="kg" FontSize="24" HorizontalAlignment="Right" VerticalAlignment="Bottom" />
                </Grid>
            </DataTemplate>
        </Grid.Resources>

        <toolkitPrimitives:LoopingSelector x:Name="loopingSelectorStarost" Margin="12" Width="128" ItemSize="128,128" ItemTemplate="{StaticResource StarostTemplate}" ManipulationStarted="loopingSelector_ManipulationStarted">
            <toolkitPrimitives:LoopingSelector.DataSource>
                <local:NumberDataSource Privzeti="18" Minimum="13" Maximum="99" />
            </toolkitPrimitives:LoopingSelector.DataSource>
        </toolkitPrimitives:LoopingSelector>
    </Grid>

编辑：这要归功于克里斯。 W.我从Phone Toolkit示例中的Generic.xaml文件中复制了该样式。我更改了<DiscreteObjectKeyFrame KeyTime="0" Value="Transparent" />视觉状态中的Selected。这是代码：

<Style TargetType="toolkitPrimitives:LoopingSelectorItem">
        <Setter Property="Foreground" Value="{StaticResource PhoneSubtleBrush}"/>
        <Setter Property="Padding" Value="6"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate>
                    <Border x:Name="root" CacheMode="BitmapCache" Background="Transparent" Padding="{TemplateBinding Padding}">

                        <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="CommonStates">

                                <VisualStateGroup.Transitions>
                                    <VisualTransition From="Normal" To="Expanded" GeneratedDuration="0:0:0.33" />
                                    <VisualTransition From="Expanded" To="Normal" GeneratedDuration="0:0:0.33" />
                                </VisualStateGroup.Transitions>

                                <VisualState x:Name="Normal" />

                                <VisualState x:Name="Expanded">
                                    <Storyboard>

                                </VisualState>

                                <VisualState x:Name="Selected">

Answer 1

首先找到它的模板，对TargetType="primitives:LoopingSelectorItem"的快速解决方案搜索应该很快公开它，或者你很可能在Blend中找到它。

获得模板后，您只需在模板中找到导致该边框的Border或Rectangle对象。

但是，如果属性已经绑定到模板，则甚至可能不需要。你能直接设置BorderBrush之类的东西吗？我不得不加载一些东西，所以我只是在猜这一点。

希望这有帮助。
