推荐答案

在控件中创建一个事件按钮。

持有两个控件的容器处理事件，通过属性读取数据，并通过其属性将其传递给另一个控件。

这样，既不控件需要知道另一个的存在，容器决定数据发生了什么，好的OOP练习也是如此。

这里有一个例子：在两种形式之间传递信息，第3部分：儿童到儿童 [ ^ ]。它关注WinForms应用程序中的表单，但原则 - 甚至代码 - 完全相同。

Create an event in the control holding the button.
The container holding the two controls handles the event, reads the data via a property, and passes it to the other control via its properties.
That way, neither control needs to know about the existence of the other and the container decides what happend to the data, as is good OOPs practice.
There is an example here: Transferring information between two forms, Part 3: Child to Child[^]. It's concerned with forms in a WinForms application, but the principles - and even the code - is exactly the same.
