我正在尝试创建一个自定义控件库。我起初以为我已经完成了表格并完全正常工作，但我没有。我没有询问如何解决表单问题，而是用我的按钮询问。
我正在制作一个可自定义的自定义按钮，每个状态都可以设置不同的颜色和文本。
我还实现了一种方法，使按钮具有不同的方向，这是目前解决问题的最简单方法，因为我确信一旦解决了这个问题，我就可以解决其余的问题。
我将首先向您展示一些代码然后解释。

我对它看起来多么垃圾严重道歉，我通常没有这样的代码。它通常很整洁。
回到主题。
让我们只关注方向。
我也知道我的代码中有很多不应该存在的问题，但这正是我尝试过的失败。
orientation属性在设计时显示在属性网格中，如果我更改它，它会将窗体上的按钮更新为垂直或水平。默认为水平。
现在，当我将其更改为垂直时，它会像之前所说的那样发生变化，但是一旦我运行代码进行测试，它就会回到默认的水平位置。
我认为问题是我在代码运行时实例化每个类，但我无法找到解决方法。
我真的需要帮助，有人可以帮助我吗？
答案 0 :(得分：1)
您需要告诉设计人员设置嵌套对象的属性：
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public OurButtonDesigner ButtonDesign { get; set; }
