MVC questions

Posted by Community Admin on 15-Aug-2012 00:00

1) How do you generate a back link where the controller method isn't in the Url. So if this is your page ~/items, then you click an item it goes to ~/items/Details/item-1. So in that detail view I put this

@Html.ActionLink("<< Back to Items", "Index")

However then the Url changes to ~/items/Index.
So that creates multiple Urls for the same content....?

2) In the above example how do we control the route such that "Details" is "details" or ideally not even visible (is that possible? ~/items/item-1)

Hi Steve,

My findings about this issue:
1) Create custom MVC route to exclude action name from route:

public static void RegisterRoutes(RouteCollection routes)

Bootstrapper.MVC.MapRoute("AgentsRoute", "Agents/urlName", new controller = "Agents", action = "Detail", urlName = UrlParameter.Optional );

in above example I remove "Detail" part of URL
2. Use custom route to generate appropriate URLs

@Html.MyRouteLink("read more", "AgentsRoute", new

controller = "Agents",

action = "Detail",

urlName = item.UrlName

)

I created Extension funtionality like it is described here: net.tutsplus.com/.../
3) Now, in order to route Sitefinity to your controller and action, you will have to create and register Sitefinity custom route:

public override System.Web.Routing.RouteData GetRouteData(HttpContextBase httpContext)

if (!VerifyRequest(httpContext))

return null;

//get the path from the httpContext variable and parse it

var virtualPathInternal = GetVirtualPathInternal(httpContext);

if (virtualPathInternal != null)

var siteMapProvider = GetSiteMapProvider();

if (siteMapProvider == null || ControlExtensions.IsBackend())

return null;

if (virtualPathInternal.EndsWith("Telerik.Web.UI.SpellCheckHandler.axd") ||

virtualPathInternal.EndsWith("Telerik.Web.UI.DialogHandler.aspx") ||

virtualPathInternal.EndsWith("ChartImage.axd"))

return null;

if (!virtualPathInternal.ToLower().StartsWith("agents/"))

return base.GetRouteData(httpContext);

bool isAdditional;

string[] pars;

var node = siteMapProvider.FindSiteMapNode(virtualPathInternal, false, out isAdditional, out pars);

if (node == null || pars == null || pars.Length == 0 || pars.Length > 2)

return base.GetRouteData(httpContext);

// Detail view

if (pars.Length == 1)

return GetRouteDataInternal(new[] "Detail", pars[0] , httpContext.Request.QueryString, node);

return null;

Above example transforms: agents/ivan-smith to agents/detail/ivan-smith

Hope it helps,
Denis.

Hello Steve,

There is not an easy way to hide the controller action name from your URL because our ActionInvoker class won't execute the action because of the path. It will search for the action in our internal dictionary and it will try to compare it with the "item-1" string instead of the real action name. Denis has proposed a nice implementation. He overrides the GetRouteData method and returns the RouteData after some custom code that analyzes the path.
