视觉树中的WP7 Popup不尊重方向

Question

我知道弹出窗口和方向存在问题.我已经读过,如果弹出窗口在可视化树中,它应该尊重方向.我有两种类型的弹出窗口,一种是全局的(不在可视化树中),另一种是在特定页面xaml上定义的.我还没有去处理全球问题,但是我希望得到一个具体的页面工作.

这是我的xaml:

    x:Class="Views.MainPanorama"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
    xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
    xmlns:controls="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls"

    FontSize="{StaticResource PhoneFontSizeNormal}"
    Foreground="{StaticResource PhoneForegroundBrush}"
    SupportedOrientations="PortraitOrLandscape"
    shell:SystemTray.IsVisible="False">

    <toolkit:TransitionService.NavigationInTransition>
        <toolkit:NavigationInTransition>
            <toolkit:NavigationInTransition.Backward>
                <toolkit:TurnstileTransition Mode="BackwardIn"/>
            </toolkit:NavigationInTransition.Backward>
            <toolkit:NavigationInTransition.Forward>
                <toolkit:TurnstileTransition Mode="ForwardIn"/>
            </toolkit:NavigationInTransition.Forward>
        </toolkit:NavigationInTransition>
    </toolkit:TransitionService.NavigationInTransition>
    <toolkit:TransitionService.NavigationOutTransition>
        <toolkit:NavigationOutTransition>
            <toolkit:NavigationOutTransition.Backward>
                <toolkit:TurnstileTransition Mode="BackwardOut"/>
            </toolkit:NavigationOutTransition.Backward>
            <toolkit:NavigationOutTransition.Forward>
                <toolkit:TurnstileTransition Mode="ForwardOut"/>
            </toolkit:NavigationOutTransition.Forward>
        </toolkit:NavigationOutTransition>

<ScrollViewer x:Name="mainScroll">
    <Grid x:Name="LayoutRoot" Style="{StaticResource BackgroundStyle}">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>

        <Image x:Name="icon" Source="/Folder;component/Images/Icons/logo.png" Height="24" Width="175" HorizontalAlignment="Left" Margin="20, 15, 0, 0" />
        <controls:Panorama Name="panMain" HeaderTemplate="{StaticResource PanoramaHeaderTemplate}" Grid.Row="1" Margin="0, -10, 0, 0" Height="680">
            <!--Panorama definition here-->
        </controls:Panorama>
        <gbl:SecureFooter ShowLock="True" x:Name="panoFoot" Grid.Row="2" VerticalAlignment="Bottom" Margin="24, 24, 24, 0" />

        <Popup x:Name="_popup" Grid.Row="3" />
    </Grid>
</ScrollViewer>

页面工作,弹出窗口,但是当我旋转手机或模拟器时,弹出窗口的内容不会改变方向.

我正在使用以下代码设置弹出窗口的内容:

_popup.Child = new OneOfTwoPopupUserControls();

这会导致弹出窗口忽略方向吗？当它在xaml中创建时,是否需要在其中包含完整内容？

如果要将Popup添加到可视树中,请使用以下行,Popup正确旋转:

LayoutRoot.Children.Add(popupInstance);
