    <p>I have this route:</p> <pre><code>{controller}/{id}/{action} </code></pre> <p>Because I think it makes more sense from RESTful perspective.</p> <p>The problem is that <code>id</code> can contain slashes (<code>/</code>) and those are treated as route separators even when encoded as "%2F". Even when I have this Web.config section in place:</p> <pre><code>&lt;uri&gt; &lt;schemeSettings&gt; &lt;add name="http" genericUriParserOptions="DontUnescapePathDotsAndSlashes" /&gt; &lt;add name="https" genericUriParserOptions="DontUnescapePathDotsAndSlashes" /&gt; &lt;/schemeSettings&gt; &lt;/uri&gt; </code></pre> <p>Because I have <code>id</code> in the middle I can't employ <code>{*id}</code> approach which captures the rest of the route including the <code>action</code>.</p> <p>It looks like my only option is to encode <code>/</code> into an RFC compliant character like <code>!</code>, however I do not want to do it using ad-hoc custom code inside controller. I want controller to receive <code>id</code> intact, already decoded. And I want my <code>Url.Action</code> to generate properly encoded URL. Is that too much to ask from MVC, or do I need to scatter ActionFilters and custom URL helpers around?</p> <p>The only way I could find is to throw in a custom <code>IRouteConstraint</code> to manipulate the <code>RouteValueDictionary</code> it receives. That sounds like a dirty hack though: a constraint manipulating its input. God knows its side effects. Do you think this is a sane enough idea, or is there a better mechanism in ASP.NET MVC allowing that? </p> <p><strong>EDIT</strong>: This workaround only works when parsing the route, not when generating one.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
