MVC3: How to link view form HTML UI with different ID to one controller/Model

Question

At first - sorry for my broken English. May be it is stupid question, but.... So, I have a model

public class AAAModel {
  public int I1 {get; set}
  public string S1 ...
  public Guid G1 ...
}

I have a controller

public ActionResult Create(AAAModel WhatToCreate){
  ...
}

And I have a proper view to enter the data... All was fine, but now I must reorganize view to create several form and give the user ability to dynamically create new objects (model) and send query to the server. The data, that I got from server cames as Ajax query and parsed to the table grid... User may view this data, correct it and may send it back. So, I make several forms wich I duplicate from initial view and change the ID and Name of the controls Originally it was like

@Html.TextBoxFor(model => model.I1)
@Html.TextBoxFor(model => model.S1)
@Html.TextBoxFor(model => model.G1)

And now it bacame like

<input id="I1_1" name="I1_1 ...>
<input id="S1_1" name="S1_1 ...>
<input id="G1_1" name="G1_1 ...>

in form 1;

<input id="I1_2" name="I1_2 ...>
<input id="S1_2" name="S1_2 ...>
<input id="G1_2" name="G1_2 ...>

in form 2, and so on... Stupid question, but how can I modify the controller or what I have to do to got these values?

P.S. These forms will send via ajax... and host-page will not reload.

Have a look here: http://blog.stevensanderson.com/2010/01/28/editing-a-variable-length-list-aspnet-mvc-2-style/ and here: http://haacked.com/archive/2008/10/23/model-binding-to-a-list.aspx

UPDATE

You can always use FormCollection to get the passed model values.

[HttpPost]
public ActionResult MyAction(FormCollection values) 
{
   string I1_2 = values["I1_2"];    
   //do something
}

If you need you can work with dynamic objects specifying @model dynamic but you don't need to as the default for views is to derive from WebViewPage<dynamic>.

Also look here if you need to pass the anonymous object https://stackoverflow.com/a/5670899/1241400

Thanks. I think about these methods. Worst that in my case I has no list. The user must submit only one form at a time, but wich one - we don't know. And we can't make the same "name" attribute inside input elements - the unobtrusive validations will broke otherwise. :( I start thinking that global redesign of the page is needed... – Сергей Никитин Oct 15 '12 at 21:02

I dont know if under stand your question correctly. And sure if your are doing this and its not working but why not just simply create multiple forms on the page . So when the user submits a certain form it will only submit the inputs in that form.

@using (Html.BeginForm("Method","Controller",FormMethod.Post,new {id="form1"}))
{
  @Html.TextBoxFor(model => model.I1)
  @Html.TextBoxFor(model => model.S1)
  @Html.TextBoxFor(model => model.G1)
  <input type="submit" name="submitButton" id=form1Submit />
}
@using (Html.BeginForm("Method","Controller",FormMethod.Post,new {id="form2"}))
{
  @Html.TextBoxFor(model => model.I1)
  @Html.TextBoxFor(model => model.S1)
  @Html.TextBoxFor(model => model.G1)
  <input type="submit" name="submitButton" id=form2Submit />
}
...

of course you are going to create this dynamically. I am sorry if i am just repeating your question

EDIT

If your issue is how to determine what set of data was submitted I would add an id field to the model and change it for every new form you create

In the simplest way the Submit of one of the form will reload all the page... And one more: does the validation will work on these forms? — Сергей Никитин, Oct 17 '12 at 20:45
you can make these Ajax forms ... `@using (Ajax.BeginForm("Index", "Home", new AjaxOptions{...}` as for validation i have never done this my self but i would asume it would work. — keshav, Oct 17 '12 at 21:04
