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.
