修改DataGrid行的背景色(c#,web)

在DataGrid的ItemDataBound事件中设定偶数行的背景色:
private void DataGrid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
   int wItemIndex=e.Item.ItemIndex;
   if(wItemIndex>0 && wItemIndex%2!=0)
      e.Item.BackColor=Color.LightGreen;
}
也可设定某一行某一列的背景色:
e.Item.BackColor->e.Item.Cell[i].BackColor
