DockPanel 中

DockPanel 根据 dock 属性按照放置在控件中的顺序对齐控件。

注意：DockPanel 是 WPF 框架的一部分，但没有 Silverlight / WinRT / UWP。但是，开源实现很容易找到。

<DockPanel LastChildFill="False">
  <!-- This will strech along the top of the panel -->
  <Button DockPanel.Dock="Top" Content="Top"/>
  <!-- This will strech along the bottom of the panel -->
  <Button DockPanel.Dock="Bottom" Content="Bottom"/>
  <!-- This will strech along the remaining space in the left of the panel -->
  <Button DockPanel.Dock="Left" Content="Left"/>
  <!-- This will strech along the remaining space in the right of the panel -->
  <Button DockPanel.Dock="Right" Content="Right"/>
  <!-- Since LastChildFill is false, this will be placed at the panel's right, to the left of the last button-->
  <Button DockPanel.Dock="Right" Content="Right"/>
</DockPanel>

<!-- When lastChildFill is true, the last control in the panel will fill the remaining space, no matter what Dock was set to it -->
<DockPanel LastChildFill="True">
  <!-- This will strech along the top of the panel -->
  <Button DockPanel.Dock="Top" Content="Top"/>
  <!-- This will strech along the bottom of the panel -->
  <Button DockPanel.Dock="Bottom" Content="Bottom"/>
  <!-- This will strech along the remaining space in the left of the panel -->
  <Button DockPanel.Dock="Left" Content="Left"/>
  <!-- This will strech along the remaining space in the right of the panel -->
  <Button DockPanel.Dock="Right" Content="Right"/>
  <!-- Since LastChildFill is true, this will fill the remaining space-->
  <Button DockPanel.Dock="Right" Content="Fill"/>
</DockPanel>
