动态改变Gridview单元格的背景颜色

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow )
{
e.Row.Attributes.Add("onmouseover", "currentcolor=this.style.backgroundColor;this.style.backgroundColor='#C0C0FF';this.style.cursor='hand';");
//当鼠标移走时还原该行的背景色
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=currentcolor");
}
}
