SetFocus for a Tabpanel within a tabcontainer

Question

I need to setfocus to a control within a tabpanel of a tabcontainer based on the input validation. The control with the erroneous input needs to be focused and the activetabindex needs to be set for the tabpanel containing the control which genearated the error

Is it possible to set activetabindex of the tabcontainer using the control's ID and set the focus to the control

Is there any good solution to proceed with..

Thanks, Anandhi
