Question

在用户控件中使用时，为什么AR未正确初始化的任何想法？我的初始化正确执行AFAIK，因为我的父表单能够成功查询。但是，当我尝试在用户控件中查询时，我得到Warning 1 An ActiveRecord class (Binder) was used but the framework seems not properly initialized. Did you forget about ActiveRecordStarter.Initialize() ? 0 0。这阻止我将用户控件拖到窗体上。如果有帮助，我会在Program.Main（）中初始化AR。

这是stacktrace：

Visual Studio设计器为您的用户控件执行OnLoad，但不运行Program.Main（）。因此，ActiveRecord未在设计器的上下文中初始化。

解决方法：使用DesignMode property检测设计模式以避免执行与ActiveRecord相关的代码，或尝试从其他事件调用ActiveRecord。

未在用户控件中初始化？
