不要尝试在用户控件中执行此操作：相反，让控件生成下一页请求事件，父表单通过关闭处理控制并开启一个新的。这样，控制器不必知道是否有更多的页面，但是父母 - 毕竟是负责的 - 确实。



听起来可能很复杂，但事实并非如此。请参阅此处：在两个表单之间传输信息，第2部分：从孩子到父母 [ ^ ] - 它是关于表单的讨论，但它对用户控件的工作方式完全相同！

Don;t try to do it from within the user control: instead, have the control generate a "next page request" event which the parent form handles by closing the control and opening a new one. That way, teh control doesn't have to know if there are more pages, but teh parent - which is in charge after all - does.

It may sound complicated, but it isn't, not at all. See here: Transferring information between two forms, Part 2: Child to Parent[^] - it's talks about forms, but it works exactly the same way for user controls!

你需要的是一个 TabControl。 [ ^ ]
