このように4つのListBoxItemがあるSplitViewペインに単純なListBoxがあります。ListViewItemをボトムに表示
<SplitView.Pane>
<ListBox SelectionChanged="ListBox_SelectionChanged" Name="mListBox" Width="250" HorizontalAlignment="Stretch">
<ListBoxItem Name="Landing_Page">
<StackPanel Orientation="Horizontal" >
<TextBlock Text="" Width="16" Height="16" FontSize="16" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="4,0,0,2" TextAlignment="Center" FontFamily="Segoe MDL2 Assets"/>
<TextBlock Text="Mainpage" Margin="16,0,0,0"/>
</StackPanel>
</ListBoxItem>
<ListBoxItem Name="Page1">
<StackPanel Orientation="Horizontal" >
<TextBlock Text="" Width="16" Height="16" FontSize="16" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="4,0,0,2" TextAlignment="Center" FontFamily="Segoe MDL2 Assets"/>
<TextBlock Text="Page1" Margin="16,0,0,0"/>
</StackPanel>
</ListBoxItem>
<ListBoxItem Name="Page2">
<StackPanel Orientation="Horizontal" >
<TextBlock Text="" Width="16" Height="16" FontSize="16" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="4,0,0,2" TextAlignment="Center" FontFamily="Segoe MDL2 Assets"/>
<TextBlock Text="Page 2" Margin="16,0,0,0"/>
</StackPanel>
</ListBoxItem>
<ListBoxItem Name="About">
<StackPanel Orientation="Horizontal">
<TextBlock Text="" Width="16" Height="16" FontSize="16" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="4,0,0,2" TextAlignment="Center" FontFamily="Segoe MDL2 Assets"/>
<TextBlock Text="About the App" Margin="16,0,0,0"/>
</StackPanel>
</ListBoxItem>
</ListBox>
</SplitView.Pane>
ここで、About ListBoxItemをSplitViewペインの下部に表示したいとします。 どうすればいいですか?
