c# - 未触发 UserControl Load 事件

Question

我有 WinForms 应用程序。我的 Form 派生类有 UserControl 派生类。我只是将几个控件放入一个 UserControl 中以简化重用。 UserControl 的 Load 事件未被触发。我必须设置一些属性吗？

尝试覆盖 OnLoad() method在您的用户控件中。来自 MSDN:

The OnLoad method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

protected override void OnLoad(EventArgs e)
{
    //Your code to run on load goes here 

    // Call the base class OnLoad to ensure any delegate event handlers are still callled
   base.OnLoad(e);
}
