I am using a ComboBox as an item renderer for a DG's column.
What do I need to do to save changed data back to DG's
dataProvider? Or will be there automatically after the change? For
example DG's column comes down with a state Illinois (code IL), I
am changing it to Indiana (code IN). Will dataProvider have
automatically IN in it and to save data to the server all I need to
do is to post it?
