[flexcoders] datagrid itemrenderer

[rthi99]

Hi all,
I am using itemrenderer on headerclick of a datagrid trying to chane 
colours based on values.
There seems to be a problem in the cells that i am not colouring.They 
are colorless and it is not the same color as the datagrid as such..
The datragrid has alternating colors for rows.How can i preserve the 
properties of the datagrid column 
Hope i am clear
thanks
