DataGrid控件的特效显示

1、交替显示颜色
private void CarInfo_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
   if(e.Item.ItemType==ListItemType.Item)
   {
    e.Item.Attributes.Add("onmouseover", "this.style.backgroundColor='yellow'");
    e.Item.Attributes.Add("onmouseout", "this.style.backgroundColor='#EEEEEE'");
   }
   if(e.Item.ItemType==ListItemType.AlternatingItem)
   {
    e.Item.Attributes.Add("onmouseover", "this.style.backgroundColor='yellow'");
    e.Item.Attributes.Add("onmouseout", "this.style.backgroundColor='Gainsboro'");
   }
}
