javascript - free-jqgrid: get 'lastSelectedData' after formatters?

Question

I am using free-jqgrid 4.9.0

is there a way to get the data from your grid just like with:

$("#my_grid").jqGrid('getGridParam', 'lastSelectedData');

but after the fields' values have been modified by formatters defined in the colModel?

update: I am talking about custom-formatters, the built-in formatters seem to apply to the data. actually the built-in formatters as well don't apply to the data.

thanks for any hints and help!
