ASP.NET如何动态创建菜单?

Question

如何动态创建一个菜单，要求后台代码实现，针对不同的用户可以显示不同的菜单项，不同的页面不同的需求都用不同的菜单项？

Answer 1

一般采用第三方控件，比如：Infragistics的UltraWebMenu

Answer 2

1、这个你可以借用微软的控件treeview，然后不同用户你输出的不同的XML信息给你这个控件进行绑定；
2、如果有直接的已经写好的div之类的静态代码，你可以直接使用前台绑定，后台输出这些html组合的数据到前台，至于数据怎么生成，根据你用户的不同权限 或者 不同分类的用户 输出不同的代码到前台页面进行绑定就行了3、如果是每个页面都不一样，那么建议你写一个输出菜单类，然后根据不同的权限或者页面来进行输出，也是后台输出数据到前台绑定希望好运。

Answer 3

自带的Treeview也挺好用的

Answer 4

把用户权限存进数据库
读权限的时候根据此来 加载不同的菜单
可以直接输出菜单并拼接html组合
或者借助第三方控件

Answer 5

用自带的TreeView导航，在后台判断用户身份，不同身份拼不同的节点

Answer 6

使用dtree 根据不同的权限绑定不同的页面

我用的标单验证，定义三个权限组，每个权限组对应不同的菜单，就直接用的if else
<% 
                                        if (Roles.IsUserInRole("Role1"))
                                        {
                                    %>
