当添加组件类VS用户控制？ [英] When to add a Component Class vs User Control?

问题描述

我有一个总体思路，并有一些明显的情况下，但也有给我一些灰色地带 - 什么时候最好使用从一个组件延伸，当它是最好创建一个用户控件？这涉及到一个具体的工作问题，我试图解决，但认为细节并不重要 - 一般这个问题的答案是足以让我。

I have a general idea, and there are some obvious cases, but there are also some gray areas for me - when is it best to use to extend from a component and when is it best to create a user control? This pertains to a specific work problem I am trying to solve, but the specifics of that are not important - a general answer to this question is enough for me.

推荐答案

在WPF和Windows Forms，两者的主要区别是，用户控件，就是要控件的集合 - 一个可重复使用，单个对象来自多个控件的自己组成的

In WPF and Windows Forms, both, the main difference is that a UserControl is meant to be a collection of controls - a reusable, single object "composed" from multiple controls themselves.

您会impelemnt而不是用户控件组件/ CustomControl /控制，如果你正在一个单一的，基本控制与新的行为，而不是打控制那小组成的控制。组件通常是一个非视觉行为，其中一个CustomControl /控制通常为视觉控制

You'd impelemnt a Component/CustomControl/Control instead of a UserControl if you are making a single, primitive control with new behavior, instead of making a "control" that's composed of smaller controls. Component usually is a non-visual behavior, where a CustomControl/Control is usually for a visual control.
