Question

This is how I think that this works

http://stackoverflow.com/questions/12333706/how-to-bla-bla-question

I think that there should be a controller action and link

@Html.ActionLink("how-to-bla-bla-question", "Questions", "Controller", new{questionId=12333706})
...
public ActionResult Questions(questionId)
{
    ...
}

Normally url should be

http://stackoverflow.com/questions/12333706/

Now is this handled by javascript or there is some other method how to make url with ID and title after it?

Answer 1

I have done exactly that like this.

Global.asax snippet:

routes.MapRoute(
        "GotoPostOrPage",
        "p/{dataItemTypeId}/{dataItemId}/{ignored}", // This allows you to append a random slug if you like
        new { controller = "DataItem", action = "Details", ignored = UrlParameter.Optional }
        );

And then something like this in the controller:

public PartialViewResult Details(int dataItemTypeId, int dataItemId)
{
    IDataItemView dataItem = _dataItemService.SelectDataItem(dataItemTypeId, dataItemId);
    DataItemViewModel vm = MappingFunctions.DataItemToViewModel(dataItem);

    return PartialView("_Details", vm);
}

Note that this allows you to append a random slug which is exactly what stackoverflow does. However, stackoverflow then corrects your slug to the one stored in the database. This would be trivial to implement.

Also note that I have shown you my real code; you’d obviously need to tweak it a little bit (but not much) to fit your scenario. The important point is to append an optional url parameter in the route table. In my case I ignore it completely, which is actually what SO does too on the way in, hence you can navigate to this daft URL and still get here: https://stackoverflow.com/questions/12051094/i-like-to-eat-cake
