StackPanel 中

StackPanel 一个接一个地放置它的控件。它就像一个停靠面板，其所有控件的停靠点都设置为相同的值。

<!-- The default StackPanel is oriented vertically, so the controls will be presented in order from top to bottom -->
<StackPanel>
  <Button Content="First"/>
  <Button Content="Second"/>
  <Button Content="Third"/>
  <Button Content="Fourth"/>
</StackPanel>

<!-- Setting the Orientation property to Horizontal will display the control in order from left to right (or right to left, according to the FlowDirection property) -->
<StackPanel Orientation="Horizontal">
  <Button Content="First"/>
  <Button Content="Second"/>
  <Button Content="Third"/>
  <Button Content="Fourth"/>
</StackPanel>

要从下往上堆叠项目，请使用停靠面板。
