custom routes with 2 parameters, id and customerid

Question

for example you have custom route like this:

CustomerOrder/{action}/{id}/customerid={customerid}

the url became like this:

CustomerOrder/Create/customerid=1

how can you get the customerid and use it in the view?

<%= Html.MenuItem("Back to List", "Index", new { customerID = ???????? })%>

Answer 1

The equals sign is going to confuse url parsers since it has special meaning.

If you were to change your route to:

routes.MapRoute("CustomerOrder", "CustomerOrder/{action}/{id}",
    new { controller = "Order", id = "" });

Then the following view code

<%= Html.MenuItem("Back to List", "Index", new { customerID = 5 })%>

Would create a link to:

CustomerOrder/Index/?customerid=5

which would work just fine.

Note

Given your current routing configuration, you would get the exact same results by deleting your CustomerOrder route since it is broken and you get the desired results from the default route.

Answer 2

I'm new to MVC but I'm thinking the controller gets a customerid parameter and that could be passed to the View (via ViewData), no?
