推荐答案
这很简单 - 复杂的是两个UC不应该知道另一个的存在。所以你做的是让UC1创建一个由父控件或表单处理的事件，并收集ID并将其传递给UC2的实例。
是的，听起来很复杂，但在实践中真的很容易！请参阅此处：在两种表格之间传递信息，第3部分：儿童与儿童 [ ^ ] - 它谈论表单，但它完全是相同的过程（毕竟，Form只是一个Control的特例）。
It's pretty simple - the complication is that the two UC's shouldn't know about the existence of the other. So what you do is have UC1 create an event which is handled by the parent control or form, and which collects the ID and passes it to the instance of UC2.
Yes, it sound complex, but it's really easy in practice! See here: Transferring information between two forms, Part 3: Child to Child[^] - it talks about forms, but it's exactly the same process (a Form is just a special case of a Control, after all).
