If any control clicked on a panel

Hi everyone, So now I have a panel and there are about 20 buttons in the panel, what I'm trying to do is instead of writing the same code for 20 different buttons, I want to write one code for all the buttons. DONT GET ME WRONG! the buttons are not doing the exact same thing. The function of these buttons is to open a link, but of course each buttons will open a different link.

So any idea on how to make this possible?

Thanks!
