【求助】关于MVVM中如何利用代码实现Command的发送？

Question

利用MVVM架构进行开发时，发现Button等控件中是可以绑定Command的，但是有些控件（如：ListBoxItem等）

无法实现Command的绑定，那么如何利用编程方法实现当某Item被选中时发送Command呢？

Answer 1

用这个 AttachedCommand，可以用一个事件去激发一个Command

或者你可以模仿Blend SDK里面的设计，用

• System.Windows.Interactivity
• Microsoft.Expression.Interactions

提供的链接好像还得用第三方的dll？

直接编程无法实现么？

Answer 3

自己也可以仿造者实现 只是WPF本身没有提供功能 可以让事件触发Command
