你好，尼克尔，

Hi Nikhil,

 

当我想修改Datagrid的黑森点击动作时.我扩展了DataGrid(我创建了一个自定义控件)并添加了AddHandlers，以便每次在标头中观察到鼠标单击时都可以.一种可以执行的方法 事件.我的要求略有不同，所以这很有意义，但是您能否在文件背后的代码中根本没有方法?这不会破坏您的MVVB模式-MVVM的用途有所不同.

when I wanted to gwet the hesder click action of a Datagrid. I extended the DataGrid (I created a custom conrtrol) and added AddHandlers so that each time the mouse click was observed in the the header  a method would execute to handle the event. I had slightly different requirements so this made sense but could you simply not have a method in your code behind file? This doesn't break youre MVVB pattern - MVVM's purpose is different. 

这不是MVVM的一种方式，但是在MVVM中，您的Viewmodel应该只响应数据的更改，而不响应实际的UI事件(例如标题单击等).

Its not a very MVVM way but in MVVM your Viewmodel should only be responding to changes in data not responding to actual UI events such as header clicks etc.

我希望有帮助吗?
