Capturing a Row single click event

I see that the _RowDblClick event nicely captures the Row and Item clicked upon. I really need that for a single click as well. I don't see that event. So I assume one must attempt to detect the coordinates of the mouse over the Row/Item? Would this be correct? Or is there a better way? If one must determine the Row/Item clicked using the _MouseDown event, is there any example code available for doing so?

That suggestion will not work for me as it is perfectly reasonable that a user would not be changing the selection in our app. I need to be able to detect the Row/Item selected so I can perform an action on that click if it occurs on a specific Row/Item.

 

Is my original idea about detecting mouse coordinates the only way of doing this? If so, is there any sample code available?
