Passing values from master page to detail

http://www.asprunner.com/forums/topic/22701-custom-dependent-dropdown-boxes/

Lets me explain a little more with an example.
Master and details in the same page edit mode

In the master I have dropdown box with prices list.

In the detail I have items with prices field, instead of changing then manually I want to change it all at once if select a new price from the list from the dropdown.
Thanks
