gridview中实现选种行变色

对gridview增加RowDataBound事件 :

  protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='Gray'");
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='white'");

        }   
    }
