Windows Phone 7 – TiltEffect和LongListSelector

我试图使用LongListSelector中的Silverlight工具包的TiltEffect.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"
              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,这不行.敲击物品时点击手势会触发,但动画无法播放.我已经尝试在LongListSelector,PivotItem和父页面上设置TiltEffect.IsTiltEnabled属性,但没有一个工作.

我有另一个PivotItem包含一个与ItemTemplate的一个简单的ListBox,它与上面的LongListSelectorItemTemplate非常相似.在其DataTemplate中将TiltEffect.IsTiltEnabled属性设置为true可根据需要进行工作.

在LongListSelector的情况下我做错了什么？

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="12,0" />
    </StackPanel>
  </ListBoxItem>
</DataTemplate>
