TabControl.VerticalAlignment = 拉伸不执行任何操作

我正在尝试使 TabControl 根据其外部空间自动调整大小（位于 StackPanel 中）：

<Window x:Class="Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="100">
    <Grid>
        <StackPanel>
            <TabControl 
                BorderBrush="Red" 
                BorderThickness="2" 
                VerticalAlignment="Stretch" 
                VerticalContentAlignment="Stretch">

                <TabItem Header="Tab1"/>
                <TabItem Header="Tab2"/>
            </TabControl>
        </StackPanel>
    </Grid>
</Window>

上面的代码片段会生成以下窗口，而我希望红色边框到达窗口的底部：

I am trying to make a TabControl to auto resize according to the its outer space(it's in a StackPanel):

<Window x:Class="Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="100">
    <Grid>
        <StackPanel>
            <TabControl 
                BorderBrush="Red" 
                BorderThickness="2" 
                VerticalAlignment="Stretch" 
                VerticalContentAlignment="Stretch">

                <TabItem Header="Tab1"/>
                <TabItem Header="Tab2"/>
            </TabControl>
        </StackPanel>
    </Grid>
</Window>

The snippet above produces the following window, whilst I want the red border to reach the bottom of the window:

您可以将高度绑定到父窗口的实际高度。

<TabControl 
    BorderBrush="Red" 
    BorderThickness="2"
    Height="{Binding Path=ActualHeight,
         RelativeSource={RelativeSource Mode=FindAncestor,
            AncestorType={x:Type Window}}}">
    <TabItem Header="Tab1"/>
    <TabItem Header="Tab2"/>
</TabControl>

You can bind the height to parent window's actual height.

<TabControl 
    BorderBrush="Red" 
    BorderThickness="2"
    Height="{Binding Path=ActualHeight,
         RelativeSource={RelativeSource Mode=FindAncestor,
            AncestorType={x:Type Window}}}">
    <TabItem Header="Tab1"/>
    <TabItem Header="Tab2"/>
</TabControl>

问题出在您的 StackPanel 上。 StackPanels 不会拉伸它们的孩子。

相反，使用 DockPanel：最后一个子级将被拉伸以填充剩余空间（请参阅 LastChildFill，默认为 true）。

<Window x:Class="Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="100">
    <Grid>
        <DockPanel>
            <TabControl BorderBrush="Red" BorderThickness="2">
                <TabItem Header="Tab1"/>
                <TabItem Header="Tab2"/>
            </TabControl>
        </DockPanel>
    </Grid>
</Window>

显式设置 VerticalAlignment 是不必要的，因为其默认值已经是Stretch。

The problem is your StackPanel. StackPanels won't stretch their children.

Instead, use a DockPanel: The last child will be stretched to fill the remaining space (see LastChildFill, which defaults to true).

<Window x:Class="Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="100">
    <Grid>
        <DockPanel>
            <TabControl BorderBrush="Red" BorderThickness="2">
                <TabItem Header="Tab1"/>
                <TabItem Header="Tab2"/>
            </TabControl>
        </DockPanel>
    </Grid>
</Window>

Explicitly setting VerticalAlignment is not necessary, since its default value is already Stretch.
