GridView鼠标移到某一行时改变该行的背景色方法?

1.方法一
双击GridView的OnRowDataBound事件；
在后台的GridView1_RowDataBound()方法添加代码，最后代码如下所示：
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) 
  {
        int i;
        //执行循环，保证每条数据都可以更新
        for (i = 0; i < GridView1.Rows.Count; i++)
        {
            //首先判断是否是数据行
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                //当鼠标停留时更改背景色
                e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#00A9FF'");
                //当鼠标移开时还原背景色
                e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");
            }
        }    
}
2.方法二
   protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //int i;
        ////执行循环，保证每条数据都可以更新
        //for (i = 0; i < GridView1.Rows.Count; i++)
        //{
        //    //首先判断是否是数据行
        //    if (e.Row.RowType == DataControlRowType.DataRow)
        //    {
        //        //当鼠标停留时更改背景色
        //        e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#00A9FF'");
        //        //当鼠标移开时还原背景色
        //        e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");
        //    }
        //}
        //如果是绑定数据行
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            //鼠标经过时，行背景色变
            e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");
            //鼠标移出时，行背景色变
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");
        }
    }
