dataGrid coloring

Question

Right now, I am trying to make a datagrid that would show the different state of a row. The datagrid is binded to a datatable, if the row state was added, the row would highlighted red, if the row was modified then it would be green. I don't know if this is possible at all. I have tried selecting the row and changing the selection color but it's not working too well. If there is a better control for this please tell me. Thank you.
