How to change datagrid row color and bold font

Question

Hi,

I have a datagrid control, In that there was few rows like below

Date	Scanned A	Scanned B	Scanned C
12/12/2013	12	13	14
Subtotal	12	13	14
07/08/2014	12	13	15
07/08/2014	12	13	15
Subtotal	24	26	30
Total	36	39	44

Here I need to highlight the sub total row. Font style = Bold and background color to differentiate from other rows.
Can we achieve this using DataGrid1_ItemDataBound event. If yes please post solution using DataGrid1_ItemDataBound event.

Thanks in Advance
