Placing my form controlls onto tab problem

Question

Hi,
 hi, i have a project which has a number of controlls e.g textboxes and drop down menues which when run, is meant to display data about project details from my ms access database based on which project is selected in my drop down menu. However, now i want to place them all in a tab control. So what i did was cut all my controlls out and placed them in my tab. When i run the application and select a project, it does not display any information regarding my projects or anything. It worked before i added the tabcontrol but when i add my form controls to my tab, it does not work. Can somebody tell me why please and how i can rectify it? Do i need to referrence the tab control?
