The following code sample shows how to create Menu based on Sitemap and Roles.

The combination of ASP.NET role management and ASP.NET URL authorization provide
a way to restrict access to Web files based on security roles.

Security trimming is a very cool feature which allows you to hide the urls based
on the users roles.

First create Web.sitemap in website also add roles for access url.



    <?xml version="1.0" encoding="utf-8" ?>

        <siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
          <siteMapNode url="~/Default.aspx" title="Home"  description="Home">
           <siteMapNode url="~/contactus.aspx" title="Contact US" description="Contact US" />
           <siteMapNode url="~/aboutus.aspx" title="About Us"  description="About Us" roles="*"/>
           <siteMapNode url="~/articles.aspx" title="Articles"  description="Articles"/>
           <siteMapNode url="~/admin.aspx" title="Admin"  description="Articles" roles="Admin"/>
        </siteMapNode>
        </siteMap>

In above site admin.aspx is display only to person who has Admin role.and roles
"*" means display for everyone.

Now,define sitemap providers in web.config file and enable security trimming

(securityTrimmingEnabled is set to true ).


<siteMap defaultProvider="XmlSiteMapProvider" enabled="true">
  <providers> <add name="UserMenuSiteMap" description="Used for Menu"
type="System.Web.XmlSiteMapProvider" siteMapFile="Web.siteMap" securityTrimmingEnabled="true"/>
                       </providers>             
                    </siteMap>
