title: Change accept button with tabs
body: <p>I have a windows form application written in C# and it has three tabs and I would like the accept button change with the active tab.  Like When I am in tab 1 I want button _1 to be the accept button but when I am in tab 3 I want button_3 to be my accept button.  I cannot figure out how to do this and maybe I'm not using the correct terms in my searches but I cannot find any good resources online showing me how to do this. </p>
