WPF对齐容器中的项目 [英] WPF align items in container

问题描述

所以我有一个简单的xaml:

So i have thi simple xaml:

    <TextBox Grid.Row="0" Grid.Column="1" Margin="10,14,10,5" BorderBrush="Magenta" BorderThickness="1" >
        <TextBox.Text >
            <Binding Path="Name" NotifyOnTargetUpdated="True" UpdateSourceTrigger="PropertyChanged" >
                <Binding.ValidationRules>
                    <DataErrorValidationRule ValidatesOnTargetUpdated="False"  />
                </Binding.ValidationRules>
            </Binding>
        </TextBox.Text>
    </TextBox>

    <Border Grid.Row="1" Grid.Column="1" BorderThickness="1" BorderBrush="Lime" Margin="10, 0, 10, 0">
        <DockPanel  Margin="0"  >
            <Button  Margin="0, 0, 5, 0" Width="100" Content="First" />
            <Button  DockPanel.Dock="Right" Width="100" Content="Second" />
        </DockPanel>
    </Border>

看起来是这样的:

我想以这样的方式放置按钮，即第一个按钮左对齐，第二个按钮右对齐.但是如您所见，第二个按钮和边框的右侧之间有一个空格.我怎么能杀死这个空间?预先感谢！

I would like to place buttons such a way that First button was left-aligned and secoond button was right-aligned. but as you can see there is a space between second button and right side of border. How could i kill off this space? Thank in advance!

推荐答案

这是因为(DockPanel的)LastChildFill在默认情况下为true，从而导致该行为. 您可以将其设置为false来解决问题:

It's because LastChildFill (of the DockPanel) is true by default causing that behavior. You can set it to false to solve the problem:

<DockPanel  Margin="0" LastChildFill="False">
        <Button  Margin="0, 0, 5, 0" Width="100" Content="First" />
        <Button  DockPanel.Dock="Right" Width="100" Content="Second" />
</DockPanel>
