Silverlight PRISM，创造一种行为
我一直在尝试在基于 PRISM 的 silverlight 项目中创建基本行为。类似于 http://csharperimage.jeremylikness.com/2009/ 10/silverlight-behaviors-and-triggers_09.html
我遇到的问题是行为的 OnAttached() 和 OnDetaching() 方法被调用得很好，但是当我设置事件处理程序时，例如 AssociatedObject.KeyDown += _TextBoxFilterBehaviorKeyDown;
关联的方法永远不会被调用。我认为这可能与它不是标准的 silverlight 项目并且基于 PRSIM 有关。
还有其他人有过这个吗？
感谢您抽出时间
I've been trying to create a basic behavior in my PRISM based silverlight project. Something like http://csharperimage.jeremylikness.com/2009/10/silverlight-behaviors-and-triggers_09.html
the problem I am having is that the OnAttached() and OnDetaching() methods of the behavior get called fine but when I set up my event handler for example AssociatedObject.KeyDown += _TextBoxFilterBehaviorKeyDown;
The associated method will never get called. I figured it may have something to do with it not being a standard silverlight project and based on PRSIM.
Has anyone else had this?
Thanks for your time

我认为 PRISM 在这里没什么用处。我建议您将调试点放在
OnAttached、OnDetached和TextBoxFilterBehaviorKeyDown方法中，以便检查是否有效地调用了所有代码在适当的时间。顺便说一句，您提供的链接不起作用，但也许此链接中的信息对您有帮助： http://www.nikhilk.net/Silverlight-Behaviors.aspx
PRISM has nothing to here I think. I would suggest that you put debug points in the
OnAttached,OnDetachedandTextBoxFilterBehaviorKeyDownmethods, in order to check that effectively all the code is being invoked at the appropriate time.By the way the link you have provided is not working, but maybe the information in this one helps you: http://www.nikhilk.net/Silverlight-Behaviors.aspx
