推荐答案

来自教程 [ ^ ]:

在某些程序中，FlowLayoutPanel可能会变得太小而无法显示所有控件.在这种情况下，可以将 AutoScroll 属性设置为True.当控件溢出封闭区域时，这将使 FlowLayoutPanel显示滚动条.

In some programs, the FlowLayoutPanel may end up being too small to show all the controls. In this case, you can set the AutoScroll property to True. This will make the FlowLayoutPanel display scrollbars when the controls overflow the enclosing area.
