Why is my ActionLink not working correctly?

I can't 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 am trying to create a link to the ServiceCall controller, Show View. From any view on the ServiceCall, this works great:

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

In Activity view, this doesn't work:

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

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

After some research, I decided to try the following:

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

This gives me the URL http: // localhost / ServiceCall / Show , but it doesn't give me the call number. Any ideas?

This is on my routes:

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

Try the following:



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

I think you are not calling the correct override. You need:

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


Pay attention to the additional null

. I recently had a similar problem.

Edit: Also, I'm sure you don't need one Html.Encode

. It's already coded.
