asp.net下让Gridview鼠标滑过光棒变色效果

代码如下:
//光棒效果
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes.Add("onmouseover", "currentcolor=this.style.backgroundColor;this.style.backgroundColor='#FFFDD7'");
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=currentcolor");
}
}
