xaml - LongListSelector 不滚动

Question

我无法让我的长列表选择器正常工作。当列表比屏幕高时，长列表选择器保持静态，我无法滚动查看所有项目。

有什么想法吗？

<phone:PivotItem Header="{Binding Path=LocalizedResources.ApplicationsHeader, Source={StaticResource LocalizedStrings}}" x:Name="applicationsPivotItem">
    <Grid x:Name="applications" Grid.Row="1">
        <phone:LongListSelector x:Name="MainLongListSelector" ItemsSource="{Binding Items}" SelectionChanged="MainLongListSelector_SelectionChanged">
            <phone:LongListSelector.ItemTemplate>
                <DataTemplate>
                    <StackPanel>
                        <TextBlock Text="{Binding LineOne}" TextWrapping="Wrap" Style="{StaticResource PhoneTextExtraLargeStyle}"/>
                        <TextBlock Text="{Binding LineTwo}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>
                    </StackPanel>
                </DataTemplate>
            </phone:LongListSelector.ItemTemplate>
        </phone:LongListSelector>
    </Grid>
</phone:PivotItem>
