推荐答案

没有子表单"和父表单".这是拥有的表单"及其所有者.
尝试在所有情况下都使用这种关系.

对于他们的协作，这种关系根本不重要.

There is no "Child form" and "Parent form". This is "Owned form" and its Owner.
Try to use this relationship in all cases.

This relationship does not matter at all when it comes to their collaboration.
Please see my Answer here:

要添加到其他答案中，请勿直接以其他形式访问控件.而是以目标形式公开一个公共属性，或者公开一个呼叫者可以挂接到的公共事件，以监听进行更改.

To add to the other answers, do not directly access a control in a different form. Instead expose a public property in the target form, or alternatively expose a public event that callers can hook on to, to listen for changes.
