TiltEffect和LongListSelector

Question

我正在尝试使用TiltEffectSilverlight工具包中的一个LongListSelector.这是在XAML中声明元素的方式:

<controls:PivotItem Header="Pivot Item">

  <controls:PivotItem.Resources>

    <DataTemplate x:Key="LongListSelectorGroupHeaderTemplate">
      <Border Background="{StaticResource PhoneAccentBrush}"
              Margin="10,20,0,0"
              HorizontalAlignment="Left"
              VerticalAlignment="Center"
              Height="{StaticResource PhoneFontSizeExtraExtraLarge}"
              Width="{StaticResource PhoneFontSizeExtraExtraLarge}">
        <TextBlock Text="{Binding Name}"
                   Style="{StaticResource PhoneTextExtraLargeStyle}"
                   Foreground="White"
                   VerticalAlignment="Bottom"
                   HorizontalAlignment="Left" />
      </Border>
    </DataTemplate>

    <DataTemplate x:Key="LongListSelectorGroupItemTemplate">
      <Border Background="{StaticResource PhoneAccentBrush}"
              Margin="10"
              Height="{StaticResource PhoneFontSizeExtraExtraLarge}"
              Width="{StaticResource PhoneFontSizeExtraExtraLarge}">
        <TextBlock Text="{Binding Name}"
                   Style="{StaticResource PhoneTextExtraLargeStyle}"
                   Foreground="White"
                   VerticalAlignment="Bottom"
                   HorizontalAlignment="Left" />
      </Border>
    </DataTemplate>

    <DataTemplate x:Key="LongListSelectorItemTemplate">
      <StackPanel Grid.Column="1"
                  VerticalAlignment="Top"
                  Orientation="Horizontal"
                  toolkit:TiltEffect.IsTiltEnabled="True">

        <toolkit:GestureService.GestureListener>
          <toolkit:GestureListener Tap="OnLongListSelectorTapped" />
        </toolkit:GestureService.GestureListener>

        <Image  Source="{Binding ImageSource}"
                MinHeight="32"
                MinWidth="32"
                MaxHeight="48"
                MaxWidth="48" />

        <TextBlock Text="{Binding Name}"
                   Style="{StaticResource PhoneTextExtraLargeStyle}"
                   Margin="12,10,12,0" />

      </StackPanel>
    </DataTemplate>

  </controls:PivotItem.Resources>

  <toolkit:LongListSelector ItemTemplate="{StaticResource LongListSelectorItemTemplate}"
                            GroupHeaderTemplate="{StaticResource LongListSelectorGroupHeaderTemplate}"
                            GroupItemTemplate="{StaticResource LongListSelectorGroupItemTemplate}">

    <toolkit:LongListSelector.GroupItemsPanel>
      <ItemsPanelTemplate>
        <toolkit:WrapPanel />
      </ItemsPanelTemplate>
    </toolkit:LongListSelector.GroupItemsPanel>

  </toolkit:LongListSelector>

</controls:PivotItem>

不幸的是,这不起作用.点击某个项目时会触发点击手势,但动画不会播放.我已经尝试TiltEffect.IsTiltEnabled在LongListSelector,PivotItem和父页面上设置属性,但它们都不起作用.

我有另一个PivotItem包含一个ListBox与上面ItemTemplate非常类似的简单LongListSelectorItemTemplate.根据需要将TiltEffect.IsTiltEnabled属性设置true为其DataTemplate工作范围.

在这种情况下,我做错了LongListSelector什么？

如果将ItemTemplate包装在ListBoxItem中,它将相应地倾斜:

<DataTemplate x:Key="LongListSelectorItemTemplate">
  <ListBoxItem>
    <StackPanel Grid.Column="1"
                VerticalAlignment="Top"
                Orientation="Horizontal"
                toolkit:TiltEffect.IsTiltEnabled="True">

      <toolkit:GestureService.GestureListener>
        <toolkit:GestureListener Tap="OnLongListSelectorTapped" />
      </toolkit:GestureService.GestureListener>

      <Image  Source="{Binding ImageSource}"
              MinHeight="32"
              MinWidth="32"
              MaxHeight="48"
              MaxWidth="48" />

      <TextBlock Text="{Binding Name}"
                 Style="{StaticResource PhoneTextExtraLargeStyle}"
                 Margin="12,10,12,0" />
    </StackPanel>
  </ListBoxItem>
</DataTemplate>
