VS 中的设计器问题：无法在传递给事件绑定服务的对象上设置事件

Question

我有一个小问题：Winform 控件（包含其他 WPF）突然停止在设计器中显示。

消息：

无法在对象上设置事件 传递给事件绑定服务 因为与相关的网站 无法定位对象。

调用堆栈：

在 System.ComponentModel.Design.EventBindingService.EventPropertyDescriptor.SetValue(对象 组件，对象值）位于 System.ComponentModel.Design.Serialization.CodeDomSerializerBase.DeserializeAttachEventStatement（IDesignerSerializationManager 经理，CodeAttachEventStatement 声明）于 System.ComponentModel.Design.Serialization.CodeDomSerializerBase.DeserializeStatement（IDesignerSerializationManager 经理，CodeStatement声明）

问题可能出在哪里？

Answer 1

从InitializeComponent 中取出任何委托或事件处理程序注册。尽管对象已正确创建，并且所有编译和工作都正常，但似乎搞砸了 VS2005 中的表单设计器。

我已经放入了一个 RegisterHandlers 方法，我可以在所有自定义表单上手动调用该方法。这并不理想，但它有效

Answer 2

刚刚在 VS 2017 中遇到了同样的错误。原因是我使用了 VB 关键字 Handles obj.event，其中 obj 是一个 WPF 对象，包含在 WinForms 表单中。
用一对 AddHandler / RemoveHandler 替换 Handles 解决了这个问题。
