I have two tabs in a form . The first form has some buttons which are common to the second tab. But there are some additional buttons in the second tab which need to be worked on . I have included the buttons in the second tab .But I am really confused how to make it functional like how do I step in my second tab and write the functions ? Can you help me out . I have class already made for the first tab . I need to include the other tab in that .
