Tab Controls problem

Hi all,
I have a repeater tabs web user control.When i search for a member, it opens first tab.
I wanna implement keyborad functionality to my application ,ie when user presses tab key the cursor should switch between and inside tabs.Lets say  the current cursor is on first tab, user presses tab key, cursor moves to next tab.When user presses enter on this tab the control should go to sub controls under this tab and again come back to tab to navigate among other tabs.
 
Thanks
