How to record actions in a compact environment?

I am working on a Windows Mobile project using a compact structure.

One thing I have to do is register when users perform actions, this can mean any action from clicking a button to using a barcode scanner. The time at which it also occurred should be recorded.

My plan is to override all controls by including the built-in logging functions in them, but this may not be the right way to do this, it seems to be a very tedious thing.

Is there a better way?
