Submitting form and pass data to controller method of type FileStreamResult

Question

I have an mvc form  made from a model  which when submitted  I want to get a parameter I have the code to set the form and get the parameter  using   Html BeginForm  myMethod    Home   FormMethod Get  new   id    item JobId          and inside my home controller I have       HttpPost      public FileStreamResult myMethod string id                 sting str   id           However  I always get the error     The resource you are looking for  or one of its dependencies  could   have been removed  had its name changed  or is temporarily   unavailable   Please review the following URL and make sure that it is   spelled correctly    When I omit the  HttpPost   the code executes file but the variables str and id are null   How can I fix this please   EDIT  Can this be caused because myMethod in the controller is not an ActionResult  I realized that when I have a method of type Actionresult where the method is bound to a view  everything works well  But the type FileStreamresult cannot be bound to a View  How can I pass data to such methods

You seem to be specifying the form to use a HTTP 'GET' request using FormMethod.Get. This will not work unless you tell it to do a post as that is what you seem to want the ActionResult to do. This will probably work by changing FormMethod.Get to FormMethod.Post.

As well as this you may also want to think about how Get and Post requests work and how these interact with the Model.

here the problem is model binding if you specify a class then the model binding can understand it during the post if it an integer or string then you have to specify the  FromBody  to bind it properly   make the following changes in FormMethod  using   Html BeginForm  myMethod    Home   FormMethod Post  new   id    item JobId           and inside your home controller for binding the string you should specify  FromBody   using System Web Http   HttpPost  public FileStreamResult myMethod  FromBody string id            Set a local variable with the incoming data      string str   id       FromBody is available in System Web Http  make sure you have the reference to that class and added it in the cs file

This is because you have specified the form method as GET  Change code in the view to this   using   Html BeginForm  myMethod    Home   FormMethod Post  new   id    item JobId

When in doubt  follow MVC conventions   Create a viewModel if you haven t already that contains a property for JobID  public class Model        public string JobId  get  set        public IEnumerable lt MyCurrentModel gt  myCurrentModel   get  set              any other properties you may need     Strongly type your view   model Fully Qualified Path To Model   Add a hidden field for JobId to the form  using   Html BeginForm  myMethod    Home   FormMethod Post                           Html HiddenFor m   gt  m JobId      And accept the model as the parameter in your controller action      HttpPost  public FileStreamResult myMethod Model model        sting str   model JobId
