title: Flash Datagrid change cell color depending upon updated data
body: <p>I have a datagrid in my Flash app whose data keeps updating quite frequently.
  On every update, I need to change the cell color of only those cells whose data has changed.
  That too, if the updated value is less than the older value then the cell color should change to RED else, GREEN.</p>
  
  <p>I have tried using labelFunction, cellrenderer, etc. But to no avail.
  By no means, I am able to access the present data in the cells to compare it with the new data.</p>
  
  <p>This has drawn me to my wits end.
  Last few hair left to be pulled out from my head!</p>
  
  <p>Thanks in Advance for any help!</p>
