How to change parent of a control

I am suing Lanwindows/CVI 2012 SP1, and I have 2 questions:

1) I created a tabpage and inserted a table. I created a button outside of the tab, near tabpage contol. How can I move the button control to tabpage? The parent of the button is the main window. I want to move it inside of the tab page. If I move it goes behind the tab page.

2) Is there a source file wich is responsible for the placing the controls on the window during start-up? 

Thanks.
