In_place_edit with submit the forum

Hi Friends,

I have implemented in_place_edit, validations also customized the
in_place_edit the buttons also

But i need to submit the total form when we are the in_place_edit fields

In my application, one select box and in_place_edit control is below to
the select box .
When we update the in_place_edit control, I also want to update the the
select box also

Please find attachment also .

I think i have to submit the total form . Can u give any ideas?
In_place_edit will work for this scenario?
