注解

Anchor使用 属性定义控件在调整其父控件大小时如何自动调整其大小。 将控件定位到其父控件可确保在调整父控件大小时,定位边缘相对于父控件的边缘保持相同的位置。

可以将控件定位到其容器的一个或多个边缘。 例如,如果 具有 FormButton 的 ,其Anchor属性值设置为 TopBottomButton则会拉伸 ,以在 的 增大时Height保持与 的上边缘和下边缘FormForm定位距离。

注意

AnchorDock 属性是互斥的。 一次只能设置一个,最后一个集优先。

继承者说明

重写派生类中的 Anchor 属性时,请使用基类的 Anchor 属性来扩展基实现。 否则,必须提供所有实现。 无需同时替代 get 属性的 Anchorset 访问器;如果需要,只能重写一个。
