    copied!<p>You should not do this. Your question is asking how to create HTML from the controller. Controllers should not create HTML. That's what a view is for. Instead, pass the category and subcategory to the view, and generate the HTML there:</p> <pre><code> public ActionResult Foo() { ViewData["category"] = "Foo"; ViewData["subcategory"] = "Bar"; return View(); } &lt;asp:Content ID="Content1" ContentPlaceHolderID="MainContentPlaceHolder" runat="server"&gt; &lt;h3&gt;Home &amp;gt; &lt;%=Html.ActionLink(ViewData["category"]) %&gt; &amp;gt; &lt;%=Html.ActionLink(ViewData["subcategory"]) %&gt;&lt;/h3&gt; </code></pre> <p>Of course, do feel free to use a strongly typed model instead of the ViewData dictionary, but this should give you a general idea.</p> <p><strong>Note: my original answer follows. The question originally posed (see back revisions) was completely different than the question as it now stands. I'm leaving the original answer, because I think there is some value in it.</strong></p> <p>Before I get the answer, I'd be remiss if I didn't say that this example is wrong in a couple of different ways.</p> <ol> <li>Whether you should use code behind it all in an MVC app is, at the very least, debatable.</li> <li>You certainly should not be setting ViewData in a view. ViewData should be set in the controller and <em>read</em> in a view.</li> </ol> <p>Now, with that said, the way to call Html.ActionLink in a code behind page is to, um, just call it. It works just fine, and return a string, just like it does in the aspx.</p> <p>However, that's not what I'd recommend doing. Instead, make a helper for your header:</p> <ol> <li>Create a new, static class. Call it ViewHelpers or something.</li> <li>Add the namespace for this class to the pages->namespaces section in web.config</li> <li>Add a new method, Header (or whatever name you prefer) to the class. See the example below.</li> <li>Now called the helper from your view. Again, see the example below.</li> </ol> <p>Examples:</p> <pre><code>public static class ViewHelpers { public static string Header(this HtmlHelper helper, string category, string subcategory) { return string.Format("Home &gt; {0} &gt; {1}", helper.ActionLink(category), helper.ActionLink(subcategory); } } &lt;asp:Content ID="Content1" ContentPlaceHolderID="MainContentPlaceHolder" runat="server"&gt; &lt;%= Html.Header("foo", "bar") %&gt; &lt;pages [...]&gt; [...] &lt;namespaces&gt; [...] &lt;add namespace="Your.Namespace.ContainingYourClass"/&gt; &lt;/namespaces&gt; &lt;/pages&gt; </code></pre>
