WPF StackPanel内容垂直对齐

标签: wpf xaml alignment stackpanel

XAML中是否有办法说我想垂直居中对齐水平导向的StackPanel内的所有组件?

我使用以下XAML

获得了所需的结果
<StackPanel Orientation="Horizontal">
     <TextBlock VerticalAlignment="Center"/>
     <Button VerticalAlignment="Center"/>
     <TextBox VerticalAlignment="Center"/>
     <Button VerticalAlignment="Center"/>
     <TextBlock VerticalAlignment="Center"/>
</StackPanel>

但我需要分别为每个控件重复VerticalAlignment="Center"

有没有办法在StackPanel级别声明如下所示?

<StackPanel Orientation="Horizontal" VERTICALCONTENTALIGNMENT="Center">
     <TextBlock/>
     <Button/>
     <TextBox/>
     <Button/>
     <TextBlock/>
</StackPanel>

您可以使用StackPanel定义Trigger的样式,该样式设置所有孩子的VerticalAlignment

<Style x:Key="HorizontalStackPanel" TargetType="{x:Type StackPanel}">
    <Setter Property="Orientation" Value="Horizontal" />
    <Style.Triggers>
        <Trigger Property="Orientation" Value="Horizontal">
            <Setter Property="FrameworkElement.VerticalAlignment"  Value="Center" />
        </Trigger>
    </Style.Triggers>
</Style>

并应用此风格:

<StackPanel Style="{StaticResource HorizontalStackPanel}">
    <TextBlock />
    <Button />
    <TextBox />
    <Button />
    <TextBlock />
</StackPanel>

它对我有用。 整个代码:

<Window x:Class="WpfApplication11.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <Style x:Key="HorizontalStackPanel" TargetType="{x:Type StackPanel}">
            <Setter Property="Orientation" Value="Horizontal" />
            <Style.Triggers>
                <Trigger Property="Orientation" Value="Horizontal">
                    <Setter Property="FrameworkElement.VerticalAlignment"  Value="Center" />
                </Trigger>
            </Style.Triggers>
        </Style>
    </Window.Resources>
    <Grid>
        <StackPanel Style="{StaticResource HorizontalStackPanel}">
            <TextBlock Text="One"/>
            <Button Content="Two"/>
            <TextBox Text="Three"/>
            <Button Content="Four"/>
            <TextBlock Text="Five"/>
        </StackPanel>
    </Grid>
</Window>

StackPanel放在Grid内,并在VerticalAlignment="Center"上设置StackPanel

定义这样的样式;

<Style x:Key="StackHorizontal" TargetType="StackPanel">
    <Style.Resources>
        <Style TargetType="TextBlock" BasedOn="{StaticResource {x:Type TextBlock}}">
            <Setter Property="VerticalAlignment"  Value="Center" />
        </Style>
        <Style TargetType="Button" BasedOn="{StaticResource {x:Type Button}}">
            <Setter Property="VerticalAlignment"  Value="Center" />
        </Style>
    </Style.Resources>
</Style>
