未在用戶控件中初始化？

Question

有關爲什麼AR在用戶控件內部使用時未被正確初始化的任何想法？我的初始化正在正確執行AFAIK，因爲我的父表單能夠成功查詢。但是，當我嘗試在用戶控件中查詢時，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。這阻止了我將用戶控件拖放到表單上。如果有幫助，我在Program.Main（）中初始化AR。

這裏是堆棧跟蹤：

at Castle.ActiveRecord.ActiveRecordBase.EnsureInitialized(Type type) 
at Castle.ActiveRecord.ActiveRecordBase.FindAll(Type targetType, DetachedCriteria detachedCriteria, Order[] orders) 
at Castle.ActiveRecord.ActiveRecordBase.FindAll(Type targetType) 
at Castle.ActiveRecord.ActiveRecordBase`1.FindAll() 
at TxLocates.BinderTabReferenceControl.BinderTabReferenceControl_Load(Object sender, EventArgs e) in C:\dev\TxLocates\src\TxLocates\BinderTabReferenceControl.cs:line 56

Visual Studio設計執行的OnLoad您的用戶控制，但不運行Program.Main（）。因此，ActiveRecord在設計器的上下文中不會被初始化。

解決方法：使用DesignMode property檢測設計模式以避免執行與ActiveRecord相關的代碼，或嘗試從其他事件調用ActiveRecord。
