推荐答案

一种方法是通过附加属性，尤其是如果您想重用此功能.

One way to do this is via an attached property, especially if you want to reuse this capability.

Expression Blend的Behavior<T>类使此过程变得简单.您将需要Blend SDK，但是您可以直接使用行为.这是显示示例的博客文章.

Expression Blend's Behavior<T> class makes this simple. You'll need the the Blend SDK, but then you can use behaviors directly. Here's a blog post showing an example.

这使您可以在XAML中分配附加行为.许多MVVM框架都有使用这种方法的实现，例如 Cinch中的LifetimeEvents .

This allows you to assign an attached behavior in XAML. Many MVVM frameworks have an implementation that uses this approach, such as the LifetimeEvents in Cinch.
