How can I pass/send values from the controller to the view.

No Model created yet

<div id="textbox"></div>
<div id="dropdown"></div>

var $textbox = $("#textbox");
var $dropdown = $("#dropdown");

[HttpPost]
public ActionResult Index()
{
    string value = values; 
    // the variable value return information to be displayed in the textbox and dropdown.
    //There might be more then one textboxes and dropdowns.

Regards
