Question

I can not figure out why ActionLink is not generating the url correctly in this one instance.

I have a controller called Activity and a view called Show. From there I’m trying to create a link to the ServiceCall controller, Show view. From within any view on the ServiceCall this works fine:

<%= Html.ActionLink(Html.Encode(sc.CallNumber), "Show", new { callNumber = "100" })%>

From the Activity view, this is not working:

<%= Html.ActionLink(Html.Encode(sc.CallNumber), "Show", "ServiceCall", new { callNumber = "100" })%>

It is generating a link like http://localhost/Activity/Show/12?Length=11

After some research I decided to try this:

<%= Html.ActionLink(Html.Encode(sc.CallNumber), "Show", new { controller = "ServiceCall" }, new { callNumber = "100" })%>  

That gives me a url of http://localhost/ServiceCall/Show but does not give the callNumber. Any ideas?

This is in my routes:

routes.MapRoute(
            "ShowCall",
            "ServiceCall/Show/{callNumber}",
            new {controller = "ServiceCall", action = "Show", callNumber = ""}
            );

Try this:

<%= Html.ActionLink(Html.Encode(sc.CallNumber), "Show", "ServiceCall", new { callNumber = "100" }, null)%>
