Question

Just one easy question about default parameter values in the routing.

If I have a route in global asax with the following data:

Name: "DetailPage"
Pattern:/{companytitle}/{departmenttitle}/{persontitle}
Controller="Person"
Action="Detail"

And I’m using the following helper in my views:

@(Url.RouteUrl("DetailPage",new{companytitle=Model.Companytitle, departmenttitle=Model.DepartmentTitle,persontitle=Model.PersonTitle}))

Lets imaging that property of the model DepartmentTitle is null, how I could set a default value in the Route?

Answer 1

Just define them as part of the route and give them default values like below:

routes.MapRoute("DetailPage",
                "/{companytitle}/{departmenttitle}/{persontitle}",
                new { controller = "Person", action = "Detail", departmenttitle = "Science", persontitle ="Me" }
                );
