DockPanel为容器控件

主要了解其Dock属性和LastChildFill属性的使用

一、LastChildFill="True"
时

代码：

<DockPanel LastChildFill="True">

            <Button DockPanel.Dock="Top">Top</Button>

            <Button DockPanel.Dock="Bottom">Bottom</Button>

            <Button DockPanel.Dock="Left">Left</Button>

            <Button DockPanel.Dock="Right">Right</Button>

            <Button>Fill</Button>

 </DockPanel>

效果图：

二、LastChildFill="False"时

代码：

        <DockPanel LastChildFill="False">

            <Button DockPanel.Dock="Top">Top</Button>

            <Button DockPanel.Dock="Bottom">Bottom</Button>

            <Button DockPanel.Dock="Left">Left</Button>

            <Button DockPanel.Dock="Right">Right</Button>

            <Button>Fill</Button>

        </DockPanel>
