从另一个表单更改按钮的visible属性 [英] change the visible property for button from another form

问题描述

您好，

我可以从其他表单更改按钮的可见属性吗？

Hello,
can i change the visible property for button from another form ??

推荐答案

您可能会找到这些提示有用：

在两个之间传输信息表格，第1部分：父母与孩子 [ ^ ]

在两个表格之间传递信息，第2部分：儿童到父母 [ ^ ]

在两种形式之间传递信息，第3部分：C hild to Child [ ^ ]

它们是关于传输数据，但您可以使用相同的方法来更改按钮的可见性。

You'll probably find these Tips useful:
Transferring information between two forms, Part 1: Parent to Child[^]
Transferring information between two forms, Part 2: Child to Parent[^]
Transferring information between two forms, Part 3: Child to Child[^]
They are about transferring data, but you can use the same ways to change the visibility of a button.

这是关于表单协作的流行问题。最强大的解决方案是在表单类中实现适当的接口，并传递接口引用而不是引用Form的整个实例。有关更多详细信息，请参阅我以前的解决方案：如何以两种形式复制列表框之间的所有项目 [ ^ ]。



另请参阅此处的其他解决方案讨论。如果应用程序足够简单，解决方案就像在一个表单中声明一些 internal 属性并将对一个表单的实例的引用传递给另一个表单的实例一样简单形成。对于更复杂的项目，这种违反严格封装的样式和松散耦合可能会增加代码的意外复杂性并引发错误，因此封装良好的解决方案将是优惠。

This is the popular question about form collaboration. The most robust solution is implementation of an appropriate interface in form class and passing the interface reference instead of reference to a "whole instance" of a Form. Please see my past solution for more detail: How to copy all the items between listboxes in two forms[^].

Please also see other solutions in this discussion. If the application is simple enough, the solution could be as simple as declaring of some internal property in one form and passing a reference to the instance of one form to the instance of another form. For more complex projects, such violation of strictly encapsulated style and loose coupling could add up the the accidental complexity of the code and invite mistakes, so the well-encapsulated solution would be preferable.

由于这个问题非常受欢迎，我以前的答案往往不太清楚，可能还不清楚够了，我决定写一篇完整的提示/技巧文章，详细的代码示例和解释：一次回答的许多问题 - Windows窗体或WPF Windows之间的协作。

As the question turned out to be very popular, and my previous answers often were not well understood, probably were not clear enough, I decided to write a Tips/Trick article complete with detailed code samples and explanations: Many Questions Answered at Once — Collaboration between Windows Forms or WPF Windows.
