DataGrid中使鼠标到达的行显示不同的颜色

核心代码：

private void grdCustomer_ItemDataBound(object sender,
         System.Web.UI.WebControls.DataGridItemEventArgs e)
{
     if(e.Item.ItemType == ListItemType.AlternatingItem ||
              e.Item.ItemType == ListItemType.Item )
     {
        e.Item.Attributes.Add("onmouseover", "this.oldcolor=this.style.backgroundColor;this.style.backgroundColor='#C8F7FF'");
        e.Item.Attributes.Add("onmouseout", "this.style.backgroundColor=this.oldcolor");
        for (int i = 0; i< grdCustomer.Columns.Count; i++ )
        {
            e.Item.Cells[i].Attributes.Add("onmouseover",
          "this.oldcolor=this.style.backgroundColor;this.style.backgroundColor='#99ccff'");
            e.Item.Cells[i].Attributes.Add(
                       "onmouseout", "this.style.backgroundColor=this.oldcolor");
         }
     }
}
