How to handle event when any cell has been modified in data grid using MVVM pattern.

Hello,

I have a data grid. I have to handle event when any cell has been modified. I need to do it in MVVM application (so I don't want to use code-behind). How it can be done? Is it possible to use any kind of command (like for button)? Is it possible to pass additional parameters for command (like CommandParameter for button)?
