c# - Unable to call Post ActionResult from View -

i trying make post request view calling actionresult in controller. there list of events in view , user can view details of event clicking event. part works. however, once view details have ability sign event. part not working.

a sample action i'm trying view:

@html.actionlink("signup", "signup", new {id = "2"}, null) 

this should access action result:

[httppost] [validateantiforgerytoken] public actionresult signup(int id) {     if (modelstate.isvalid)     {         var registratie = new registratie(user.identity.getuserid(), id);         _db.registraties.add(registratie);         _db.savechanges();         return redirecttoaction("index");     }      return view("index"); } 

however, getting 404 error. think can't find actionresult?

the details action result on same page , works:

// get: /eventplanner/details/5 public actionresult details(int id) {     var evenement = _db.evenementen.single(e => e.id == id);      return view(evenement); } 

i don't understand why signup gives 404. ideas?

you cant use actionlink making post request. have following alternatives.

1. use submit button post form
2. use ajax.actionlink()
3. use jquery.ajax.

i recommend submit button because feel simpler rest.

as example first approach. try this

razor:

@using (@html.beginform("actionname", "controllername")) {     <input type="hidden" name="id" value="2" />     <input type="submit" value="post" /> } 

controller:

public class controllernamecontroller : controller {        [httppost]         public actionresult actionname(string id)         {             //your stuff              return view();         } }
