    <p>I have the following route defined in my Global.asax (MVC 3 web project):</p> <pre><code>routes.MapRoute( "BlogCategory", // Route name "Blog/Category/{*category}", // URL with parameters new { controller = "Blog", action = "Index", category = "" } // Parameter defaults ); </code></pre> <p>And my action accepts a category parameter, looking like this:</p> <pre><code> public ViewResult Index(string category, int page = 1) { PostListViewModel viewModel; if (string.IsNullOrEmpty(category)) { ....show all cats else show only the one passed in </code></pre> <p>This works fine and will pass the category through to the controller, filtering my results appropriately.</p> <p>My problem is when one of the categories I created looks like this for it's category name:</p> <blockquote> <p>Projects / Lab</p> </blockquote> <p>(note the spaces and slash)</p> <p>This creates a URL similar like this:</p> <blockquote> <p>/Blog/Category/Projects%20/%20Lab</p> </blockquote> <p>And when I follow the link, I get this error:</p> <blockquote> <p>Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. </p> <p>Requested URL: /Blog/Category/Projects / Lab</p> </blockquote> <p>It never reaches the index action when debugging.</p> <p>My question is, how can I make this work, or must I do some input validation when creating category names to prevent this from occurring?</p>

    1. COHave you considered passing around a category ID instead?

    2. COYou definitelly need to do a trim to the entered value. And not just check for spaces... some characters don't get displayed in a URL ("Ñ" or other non english chars)... remember there are other languages out there. So, to avoid all this... I suggest you to go for the category ID.

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.
