我只想在左侧显示流畅的文本,在右侧显示帮助框。
帮助框应一直延伸到底部。
如果您取出下面的外部StackPanel
,效果会很好。
但是出于布局的原因(我动态插入 UserControls),我需要包装 StackPanel
。
如何让 GroupBox
向下延伸到 StackPanel
的底部,如您所见,我已经尝试过:
VerticalAlignment="拉伸(stretch)"
VerticalContentAlignment="拉伸(stretch)"
高度=“自动”
XAML:
<Window x:Class="TestDynamic033.Test3"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Test3" Height="300" Width="600">
<StackPanel
VerticalAlignment="Stretch"
Height="Auto">
<DockPanel
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Height="Auto"
Margin="10">
<GroupBox
DockPanel.Dock="Right"
Header="Help"
Width="100"
Background="Beige"
VerticalAlignment="Stretch"
VerticalContentAlignment="Stretch"
Height="Auto">
<TextBlock Text="This is the help that is available on the news screen." TextWrapping="Wrap" />
</GroupBox>
<StackPanel DockPanel.Dock="Left" Margin="10" Width="Auto" HorizontalAlignment="Stretch">
<TextBlock Text="Here is the news that should wrap around." TextWrapping="Wrap"/>
</StackPanel>
</DockPanel>
</StackPanel>
</Window>
谢谢 Mark,使用 DockPanel
而不是 StackPanel
清除了它。一般来说,我发现自己现在越来越多地使用 DockPanel
进行 WPF 布局,这是固定的 XAML:
<Window x:Class="TestDynamic033.Test3"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Test3" Height="300" Width="600" MinWidth="500" MinHeight="200">
<DockPanel
VerticalAlignment="Stretch"
Height="Auto">
<DockPanel
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Height="Auto"
MinWidth="400"
Margin="10">
<GroupBox
DockPanel.Dock="Right"
Header="Help"
Width="100"
VerticalAlignment="Stretch"
VerticalContentAlignment="Stretch"
Height="Auto">
<Border CornerRadius="3" Background="Beige">
<TextBlock Text="This is the help that is available on the news screen." TextWrapping="Wrap"
Padding="5"/>
</Border>
</GroupBox>
<StackPanel DockPanel.Dock="Left" Margin="10" Width="Auto" HorizontalAlignment="Stretch">
<TextBlock Text="Here is the news that should wrap around." TextWrapping="Wrap"/>
</StackPanel>
</DockPanel>
</DockPanel>
</Window>
最佳答案
听起来您想要一个 StackPanel
,其中最后一个元素用尽所有剩余空间。但为什么不使用DockPanel
呢?用 DockPanel.Dock="Top"
装饰 DockPanel
中的其他元素,然后您的帮助控件就可以填充剩余空间。
XAML:
<DockPanel Width="200" Height="200" Background="PowderBlue">
<TextBlock DockPanel.Dock="Top">Something</TextBlock>
<TextBlock DockPanel.Dock="Top">Something else</TextBlock>
<DockPanel
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Height="Auto"
Margin="10">
<GroupBox
DockPanel.Dock="Right"
Header="Help"
Width="100"
Background="Beige"
VerticalAlignment="Stretch"
VerticalContentAlignment="Stretch"
Height="Auto">
<TextBlock Text="This is the help that is available on the news screen."
TextWrapping="Wrap" />
</GroupBox>
<StackPanel DockPanel.Dock="Left" Margin="10"
Width="Auto" HorizontalAlignment="Stretch">
<TextBlock Text="Here is the news that should wrap around."
TextWrapping="Wrap"/>
</StackPanel>
</DockPanel>
</DockPanel>
如果您所在的平台没有可用的 DockPanel
(例如 WindowsStore),您可以使用网格创建相同的效果。这是使用网格完成的上述示例:
<Grid Width="200" Height="200" Background="PowderBlue">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<StackPanel Grid.Row="0">
<TextBlock>Something</TextBlock>
<TextBlock>Something else</TextBlock>
</StackPanel>
<Grid Height="Auto" Grid.Row="1" Margin="10">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="100"/>
</Grid.ColumnDefinitions>
<GroupBox
Width="100"
Height="Auto"
Grid.Column="1"
Background="Beige"
Header="Help">
<TextBlock Text="This is the help that is available on the news screen."
TextWrapping="Wrap"/>
</GroupBox>
<StackPanel Width="Auto" Margin="10" DockPanel.Dock="Left">
<TextBlock Text="Here is the news that should wrap around."
TextWrapping="Wrap"/>
</StackPanel>
</Grid>
</Grid>
