DataGrid实现自定义分页，鼠标移至变色

 protected void GridView_..._RowDataBound(object sender, GridViewRowEventArgs e)

            ////鼠标划过改变列表状态
            e.Row.Attributes.Add("OnClick",url);
            e.Row.Attributes.Add("onmouseover", "Ovr(this,'#C9E4FE');");
            e.Row.Attributes.Add("onmouseout", "Out(this,'#FFFFFF');");
        }
    }

//初始化页码，页面数，及总记录数
