Silverlight developing creating 5 user controls

Question

Hi Friends,
Can you help to develop this kind of scenario.
I need to develop  a user control ( like address control which  has drop downs and text boxs). From the code behind I may need to create   some times 5 controls  somes times 3 controls.
Well  the user enters  data into 5 user controls , and the user controls fileds like countries  and states , i need to get from the data base. Well user enters data into text boxes and  selects the  country and  states.
So  i have 5 user controls in the page , at this instant , if user clicks save button then  the corrsopinding data should be updated to 2 different tables.
Thanks in advance
