ASP.NET2.0下为GridView添加鼠标滑过（onmouseover、onmouseout）

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //将满足特定条件的行标为高亮
        if (e.Row.RowType == DataControlRowType.DataRow)//判定当前的行是否属于datarow类型的行
        {
            int money = Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "MONEY"));//取当前行的列值
            if (money == 77)
                e.Row.BackColor = Color.Red;
            //string customer = (string)DataBinder.Eval(e.Row.DataItem, "CUSTOMER");
            string customer = DataBinder.Eval(e.Row.DataItem, "CUSTOMER").ToString();
            if (customer == "sdf")
                e.Row.BackColor = Color.Red;
        }
        //加入鼠标滑过的高亮效果
        if (e.Row.RowType == DataControlRowType.DataRow)//判定当前的行是否属于datarow类型的行
        {
            //当鼠标放上去的时候 先保存当前行的背景颜色 并给附一颜色
            e.Row.Attributes.Add("onmouseover", "currentcolor=this.style.backgroundColor;this.style.backgroundColor='yellow',this.style.fontWeight='';");
            //当鼠标离开的时候 将背景颜色还原的以前的颜色
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=currentcolor,this.style.fontWeight='';"); 
        }
        //单击行改变行背景颜色
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
　          e.Row.Attributes.Add("onclick","this.style.backgroundColor='#99cc00'; this.style.color='buttontext';this.style.cursor='default';");
        } 

//当有编辑列时，避免出错，要加的RowState判断
            if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
            {   
               ((LinkButton)e.Row.Cells[4].Controls[0]).Attributes.Add("onclick", ";confirm('你确认要删除：/"" + e.Row.Cells[2].Text + "/"吗?')");
            }
