Displaying datagrid row in Bold font

Hi....
After assigning the datasource to the datagridview
private void dataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
for (int rowIndex = 0; rowIndex < dataGridView1.Rows.Count; rowIndex++)
{
if (dataGridView1.Rows[rowIndex].Cells["Status"].Value != null)
{
if ((bool)dataGridView1.Rows[rowIndex].Cells["Status"].Value)
{
//read mail
}
else
{
//Unread Mail
dataGridView1.Rows[rowIndex].DefaultCellStyle.Font = new Font(Font.FontFamily, Font.Size, FontStyle.Bold);
}
}
}
}
