Answer 1

It seems to me like you are trying to get multiple values into the POST controller. In that case, and by your exam, the value from the hidden input is enough. In that case, you can setup your controller as so:

public ActionResult Index()
{
    Hidden hd = new Hidden();
    return View(hd);
}

[HttpPost]
public ActionResult Index(IEnumerable<string> hiddens)
{
    foreach (var item in hiddens)
    {
        //do whatter with item
    }
    return View(new Hidden());
}

and as for your view, simple change it in order to bind to the same name "hiddens" as so:

@using (Html.BeginForm(new { id = "postform" }))
{
    <input type="hidden" value="7" name="hiddens" />
    <input type="hidden" value="2" name="hiddens" />

    <input type="submit" value="Match" />
}

Hope this serves what you are looking forward to.

Answer 2

if your hidden value is static.Than try this

View

@using (Html.BeginForm(new { id = "postform" }))
{


 @Html.HiddenFor(m=>m.hiddevalue)
    <input type="hidden" id="" value="7" name="hidden1" />
    <input type="hidden" id="" value="7"  name="hidden2"/>

    <input type="submit" value="Match"/>
}

Controller

[HttpPost]
public ActionResult MapIcon(Hidden hidden, string hidden1, string hidden2)
{
    var hiddenvalue = hidden.hiddevalue;
    var hiddenvalue1 = hidden1;
    var hiddenvalue2 = hidden2;
    var value=hidden.hiddevalue;//null
    FormCollection col = new FormCollection();
    var value = col["hidden1"];
  //  string value = mycontroler.ControlName;

    return View(hidden);
}

Script

 $(document).ready(function () {

 $('#hiddevalue').val("Jaimin");

});

Try this, In Razor view:

@using (Html.BeginForm(new { id = "postform" }))
{
      @Html.HiddenFor(m=>m.hiddevalue)
     <input type="submit" value="Match"/>
}
