[flexcoders] datagrid cell renderers

[blc187]

i am creating a custom datagrid that uses itemrenderers on 
DataGridColumn to make custom cells.

var col1:BasicDataGridColumn = new DataGridColumn() ;
col1.itemRenderer = itemRenderer;
...
this.columns = new Array(col1, col2, col3) ;


using the itemrenderers this way, is there any way to access one 
entire row of cells? 
for example: can i load a background into a row instead of each 
specific cell?
