我何时真正需要InamingContainer接口? [英] When do I really need InamingContainer Interface?

问题描述

我在MSDN中阅读过InamingContainer是用于创建唯一名称的标记界面.何时真正必要?

I read in MSDN InamingContainer is a marker interface for creating unique name. When is it really necessary ?

推荐答案

坦白说，当控件中有一个带有ID的孩子时，这是必需的.尽管可以在单个页面上使用控件的多个实例，但必须使用 INamingContainer 界面标记控件.这是 CompositeControls 的最佳选择，因此默认情况下已派生 INamingContainer .

Frankly, it's required when your control has a child with an id. Whereas you can use multiple instances of your control on a single page, you have to mark your control with INamingContainer interface. This is the most senario for CompositeControls, thus it has derived INamingContainer by default.
