上移时排序

写给自己看，有种感觉是自己怎么越来越烂，越来越困。

前台代码：
 <asp:TemplateField HeaderText="移动">
                                            <ItemTemplate>
                                                <asp:LinkButton ID="lkbtnUp" runat="server" CommandName="up" CommandArgument='<%# Eval("ID")%>'><IMG src="../images/up.jpg" align="absMiddle" border="0" width="13" height="9"></asp:LinkButton>
                                                <asp:LinkButton ID="lkbtnDown" runat="server" CommandName="down" CommandArgument='<%# Eval("ID")%>'><IMG src="../images/down.jpg" align="absMiddle" border="0" width="13" height="9"></asp:LinkButton>
                                            </ItemTemplate>
Get操作： public virtual DataTable Get()
        {
            string sql = "select Max(sort) as max ,Min(sort) as min  from news ";
            return dataOperation.SelectTable(sql);
        }

            nRule.Updatenews(nCurrent, sortid);
            nUp["sort"] = sortcurrent -1;
            string sortid1 = nUp["id"].ToString();
           nRule.Updatenews(nUp, sortid1);
        }
        if (e.CommandName == "Delete")
        {
            if (nRule.Deletenews(e.CommandArgument.ToString()))
            {    Alert("删除成功");     }
            else    {    Alert("删除失败");  }
        }
        DataLoad();
