Call one event in another event.

Hello All
Can anyone please explain, how we can call event of one control in another event. For ex. I have two buttons, Button A and Button B. 
I perform some action on button click event of Button A. Now on click of second button i.e. Button B, i want to call the button clicj event of Button A. I have heard about the concept of delegates. Is is it possible to perform the same with the delegates ? 
Thanks in advance.
