我正在制作一个简单的应用程序,但在不同的状态(完整、快照等)方面遇到了一些麻烦。
下面是我的应用在横向全屏视图中的外观。如您所见,它有 2 个网格。一个左对齐,一个右对齐:
现在,当用户将我的应用程序向左或向右对齐时,我只希望第二个网格(右侧:Grid TWO)在对齐模式下可见,如下所示:
我们怎样才能做到这一点?
我已经尝试了几件事,但我当前的代码也不起作用。我知道这是错误的,但无论如何都是这样:
<!-- Back button and page title -->
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Button x:Name="backButton" Click="GoBack" IsEnabled="{Binding Frame.CanGoBack, ElementName=pageRoot}" Style="{StaticResource BackButtonStyle}"/>
<TextBlock x:Name="pageTitle" Grid.Column="1" Text="{StaticResource AppName}" Style="{StaticResource PageHeaderTextStyle}"/>
</Grid>
<Grid Grid.Row="1" Margin="120, 30, 0, 0" HorizontalAlignment="Stretch">
<ListBox x:Name="theList" HorizontalAlignment="Left" Width="240" VerticalAlignment="Stretch" BorderBrush="{x:Null}" Background="{x:Null}">
<ListBox.ItemTemplate>
<DataTemplate>
<ListBoxItem Content="{Binding Name, Mode=TwoWay}" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<TextBox x:Name="theNote" Text="{Binding ElementName=theList, Path=SelectedItem.Content, Mode=TwoWay}" AcceptsReturn="True" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="245,0,10,0" BorderBrush="{x:Null}" BorderThickness="0" />
</Grid>
<VisualStateManager.VisualStateGroups>
<!-- Visual states reflect the application's view state -->
<VisualStateGroup x:Name="ApplicationViewStates">
<VisualState x:Name="FullScreenLandscape"/>
<VisualState x:Name="Filled"/>
<!-- The entire page respects the narrower 100-pixel margin convention for portrait -->
