Question

I have a form in MVC:

<% using (Html.BeginForm("Get", "Person"))
  { %>
      <%= Html.TextBox("person_id")%>
      <input type="submit" value="Get Person" />
  <% } %>

This redirects me to Person/Get. Okay. The question:

How do I make this Form so it redirects me to Person/Get/{person_id}?

Edit:

<% using (Html.BeginForm("Get", "Person", new { id = ??? }))
  { %>
      <%= Html.TextBox("person_id")%>
      <input type="submit" value="Get Person" />
  <% } %>

What do I write in ???

Answer 1

I think the most difficult way would be using a javascript clientside.

The more straightforward way is to retrieve it on the action Person/Get and from there return a RedirectResult pointing to Person/Get/{person_id}

[HttpPost]
public ActionResult Get(string person_id)
{
    return RedirectToAction("Get", "Person", new { id = person_id });
}

[HttpGet]
public ActionResult Get(string id)
{
     //Do your thing
}

The redirect is usually so fast that the user will never notice. He/she will arrive at /Person/Get/{person_id}
