鼠标停留在GridView某行的颜色改变

1、protected void gvdegreetype_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='GhostWhite'");
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='white'");
        }
    }

2、 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
 //当鼠标移到的时候设置该行颜色为""， 并保存原来的背景颜色
 e.Row.Attributes.Add("onmouseover", "currentcolor=this.style.backgroundColor;this.style.backgroundColor='#6699CC'");
 //当鼠标移走时还原该行的背景色
 e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=currentcolor");
}
