Windows 8 Xaml-根据方向更改GridView布局

Question

So im pretty sure this should be a quick easy fix, yet I cant seem to figure it out. Im trying to change the layout of my GridView based on device orientation, all within Xaml. For Example:

Horizontal(scrolls horizontally)
Item1 item2 item3
item4 item5 item6

Vertical (scrolls vertically)
item1
item2
item3
item4
item5
item6

    <StackPanel Orientation="Horizontal" RequestedTheme="Light">
        <GridView TabIndex="1"  Grid.Row="2" ItemClick="LooksDetailItemClick" 
                                               IsItemClickEnabled="True" IsSwipeEnabled="False"     
                                               Padding="10,10,10,10" SelectionMode="Single" 
                                               ItemsSource="{Binding subItems}"  Height="auto" Width="auto" HorizontalAlignment="Left"
                                               VerticalAlignment="Top" Background="WhiteSmoke" HorizontalContentAlignment="Left" >
            <GridView.ItemTemplate>
                <DataTemplate>

                    <Grid x:Name="InnerGrid" Grid.Column="1"  Height="auto" Width="364">
                        <Grid.RowDefinitions>
                            <RowDefinition Height="0"/>
                            <RowDefinition Height="280"/>
                        </Grid.RowDefinitions>

                        <Grid x:Name="OtherGrid" Grid.Row="2" Grid.Column="2" Margin="29,0,35,0">
                            <Grid.RowDefinitions>
                                <RowDefinition Height="30"/>
                                <!--TitleBox-->
                                <RowDefinition Height="354*"/>
                            </Grid.RowDefinitions>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="195*"/>
                                <!-- Right Box Text -->
                                <ColumnDefinition Width="130*"/>
                            </Grid.ColumnDefinitions>

                            <TextBlock  Text="{Binding name}" VerticalAlignment="Top" TextWrapping="Wrap" HorizontalAlignment="Left" 
Width="auto" Height="auto" Margin="0,0,-198,0" />
                            <Image Source="{Binding imagePath}"  Grid.Column="0" Grid.Row="1" Stretch="Fill" Height="212" Width="141" 
    VerticalAlignment="Top" HorizontalAlignment="Left"  Margin="10,0,20,0"/>

                            <StackPanel Grid.Column="2" Grid.Row="2" Orientation="Vertical">

                                <TextBlock  Text="Style:" FontSize="24" Margin="0, 10, 0, 0"/>
                                <TextBlock  Text="10000023" FontSize="10.667" Margin="0, 10, 0, 0"/>
                                <TextBlock Text="{Binding price}" FontSize="24" Margin="0, 10, 0, 0"/>
                                <TextBlock Text="Color:" FontSize="24" Margin="0, 10, 0, 0"/>

                                <GridView   Height="130" ItemsSource="{Binding colors}">
                                    <GridView.ItemTemplate>

                                            <Image Source="{Binding Color_Image}"  Width="40" Height="40" HorizontalAlignment="Left"/>
                                        </DataTemplate>
                                    </GridView.ItemTemplate>
                                </GridView>

Unfortunately, you can't do it all within XAML except via something like a LayoutAwarePage, which is no longer supported. As such, you'll need to create your own implementation of that, which would not be an "all within XAML" solution.
