ASP。NET中怎么动态添加栏目？（高分）

Question

比如首页中有4个栏目：A，B，C，D分别下面有各自的新闻
我想在后台控制前台，添加一个E栏目出来，E栏目下也能添加自己的新闻信息等等
当然不能破坏网页格式了，请问该怎么实现？或者有具体的代码更好，油巷：[email protected]
另行追加100分！

Answer 1

我也想啊，做控件什么的都不是难题，难就难在怎么样自动的添加到那个位置上啊？
网页肯定是我用table来定位的啊，2行2列的table,现在table里有4个栏目了，我该怎么让这个新添加的栏目放到3行1列上？再添加一个就自动放到3行2列上？等等还希望高手赐教啊！

Answer 2

一个房型一个tabale 然后房间一个td

Answer 3

楼上说的是已经定制好有多少数据了吧？
我要的是N行2列的table，动态添加栏目，添加多少不限制，就按照N行2列的样子一直排下去，我从后台添加，然后插到数据库，前台再读数据，然后把我添加的栏目显示出来，就是动态添加，不知道该怎么就能添加上去啊~~~请教啊！
看下楼主代码，希望有启发，问题解决再追加100分

Answer 6

你先不要在页面上固定table，你在后台控制table的大小，你从数据库读出来的栏目在循环放在这个table里，然后在显示在页面上
如 ：定义一个public的字符串str=""
str="<table>"
for（int i=0; i<dt.rows.count;i++）//dt是一个datatable你读的数据
{
str+="<tr><td>"+dt.rows[i]["数据字段"].ToString()+"</td><tr>"
}
str+="</table>"
//具体样式你自己控制
在前台页面上就用<%=str%>把table放在想方的位置
//这是一个笨办法，希望能给你一些帮助
