You could create a “global”
variable (instance member) to act as the dataProvider for the totals DataGrid.
It would be an array of objects, with properties for each column.
Loop over the dataProvider, do the
calculations, and update the variable in the result handler, or on cellEdit if
the dg is editable.

Subject: Re: [flexcoders] Re:
Datagrid columns resize
I have a data grid with three columns. NAME AGE
and WEIGHT. I want to be able to get the total of the age and weight columns
and place them in the bottom row which you showed me how to do
previously.
Thanks.
