Question

How do you do conditional content rendering in ASP.NET MVC depending on User.IsInRole()? Tried all matches i could find here, at SO but still not satisfied. I need to hide action links depending on user roles so first i thought of a helper like

public static MvcHtmlString ActionLink(this HtmlHelper html, string linkUrl, string linkText, object htmlAttributes, bool alwaysVisible, params string[] roles)

but then I realized that I often needed to hide the outer content too (for example, <li></li> in the menu where my links were placed into). I follow the recommendation from best practices and have UrlHelperExtension so my typical links look like:

<a href="@Url.SomeStuff()">some stuff</a>

and I can’t try the idea to implement the helper over RouteLink() that will grab AuthorizeAttribute from appropriate controller methods can I?. What’s your solution?

I tend to use something along the lines of:

@if (User.IsInRole("Role")) {
<li>
  <a href="@Url.SomeStuff()">Some stuff</a>
<li>
}

This way I can have multiple links per role if needed.
