[flexcoders] DataGrid data accessed from Item renderer

[markgoldin_2000]

This is a combobox change event handler used as an itemRenderer in 
DataGrid:
public function handleDataChanged(event:ListEvent):void 
{       
        // update underlying data
        data.person = selectedItem.data; 
        // Globally store updated row
        mx.core.Application.application.globalDataToSave = data;
}   

I am also trying to create a generic Save routine. For that I am using 
globalDataProviderToSave to "remember" the modified data. But the user 
can change multiple rows in the grids before he clicks on Save. I need 
to store the whole grid data into globalDataProviderToSave to be able 
to save all rows. How can I access it from within item renderer every 
time the user changes data? Differnet ideas?

Thanks
