Detect Control Click In Form?

Ok before I get flamed hear me out. I have a form with panels containing tablelayoutpanels containing various amounts of controls that alternate visibility. On the form in its entirety I am looking at roughly 3200 controls most of which are radio buttons.

Now that being said, I am trying to figure out a way to capture what control (mainly radiobutton) is being clicked on through the forms events. So far my attempts have failed with mousedown, mouseclick, etc. Yes I know I can use the "handles radiobutton1.Clicked" event directly. However with that many radiobuttons....I know that there has to be a better way to do this. An API, windows hook, something. So far my efforts to find an alternative method have failed.
