附加属性的各种用途是什么? [英] What are the various uses of Attached Properties?

问题描述

到目前为止，我已经在 WPF 中看到了一些非常不同的 AttachedProperties 用途，我想知道，有哪些不同的用途?

I've seen some really varying uses of AttachedProperties so far in my adventures in WPF, and am wondering, what are some of the various uses?

我见过相当普通的用途，例如在 Grid 和 Canvas 中发现的用途，以及一些非常酷的 hacks，允许在没有 setter 的情况下绑定到集合.您为 AttachedProperties 找到了哪些其他应用程序?(代码示例真的很有帮助！)

I've seen fairly mundane uses, such as those found in Grid and Canvas, as well as some really cool hacks allowing binding to collections without setters. What other applications have you found for AttachedProperties? (Code samples really helpful!)

查看附加的行为.

将行为附加到对象只是意味着让对象做它不会做的事情自己的

Attaching a behavior to an object simply means making the object do something that it would not do on its own

通过附加行为实际上可以做的事情的可能性是无限的，但它通常可以减少扩展控件或向后面的代码添加逻辑的需要.

The possibilities are pretty limitless on what you can actually do through attached behaviours but it can often reduce the need to extend controls or add logic to a code behind.
