求教下高手这个要怎么解决，要怎么弄才能进行后台操作

谢谢3楼的，虽然不是用的你这个方法解决的，但是还是谢谢了

c#(asp.net)几个不同从前台页面操作后台

第一种
<%=RetInfo("DB","数据库") %>
<%=RetInfo("YX_UpFile","上传文件") %>
<%=RetfileInfo("Include/", "广告")%>
//从前台调用后台方法
//从前台调用后台的方法..并向其方法传入不同的参数!
第二种
<ItemTemplate >
<%#Ret_stat(Convert.ToInt16(Eval("YX_Stat1")), "热点")%>
<%#Ret_stat(Convert.ToInt16(Eval("YX_Stat2")), "置顶")%>                                <%#Ret_stat(Convert.ToInt16(Eval("YX_Stat3")), "推荐")%>   
<%#Ret_stat(Convert.ToInt16(Eval("YX_NewsSH")), "审核")%>
</ItemTemplate>这样的一种显示向后台传值更改信息//和第一种相似
第三种
<asp:TemplateColumn HeaderText="操　　作">
<ItemTemplate >
<a href="?YX_FS=Edit&YX_MID=<%#Eval("YX_ID")%>">修改</a>
<a href="?YX_FS=Del&YX_MID=<%#Eval("YX_ID")%>">删除</a>
</ItemTemplate>
<HeaderStyle CssClass="style3" />
</asp:TemplateColumn>        从前台同一页面连接并传值
第四种
<%# Eval("YX_TitleHelp")%>//邦定
<%# Stat(Convert.ToInt16(Eval("YX_ID")), Convert.ToInt16(Eval("YX_LyHF")))%>//前台页面调用后
台方法并给它传值

第四种:
<%=tel %> 这样调用后台的变量值
后台:
public string tel="";

没看太懂

兄弟前来顶帖。。。。
