Where does "Non-Click" Behaviour fit into a MVVM Application?

I can expose ICommands from my ViewModels but where does Non-Click/Command behaviour fit开发者_StackOverflow社区 into a MVVM Application? eg. Drag & Drop, Hover etc

Have a look at this post:

Shows how you can still use the MVVM pattern effectively for "Non-Click / Command" behaviour such as drag / drop.

I would place them in the code-behind because this is UI behaviour, I don't know if it's "right" but I think you shouldn't overcomplicate such easy things.
