how to fire event from a nested tabpanels to viewport

[Maharshi]

Hi,

I have a TabPanel inside a tabPanel added to the south region of the viewport.
The inner tabpanel has a grid panel.My question is ,
I want to fire an event from this gridpanel to the parent container which is viewport.
Please advice me how to do it?
my layout is like this

ViewPort---(event should be handled here)
|____Tab Panel (South region of viewport)
|_____TabPanel
|____Panel (added for some specific reasons)
|____GridPanel (want to fire event from here)

Any help would be highly appreciated.Thanks.

Events are not fired from-to. See http://blog.extjs.eu/know-how/events-explained/ for more details.
