Asp Net Mvc: Can JSON data be returned from Partial View?

I want to do something like this; - I'll send a Post request to an action(partial view or something else, i don't know) method with javascript. - Before this action will show me a partial view. - Partial View will also have a form and the user will enter data. - Finally, I will send this data back as the JSON data of my javascript post request.

[HttpPost]
    public ActionResult GetInformation()
    {
        // The ShowForm method returns Partial View, I know.
        // But how do I get and return the data entered in PartialView?
        var data = ShowForm();

        return Json(data);
    }

    public PartialViewResult ShowForm()
    {
        .....
        return new PartialViewResult(); 
    }

As above I want a method of returning JSON data. However, I need to add the PartialView image to the Html page with C #. Then I have to take the data from the form and return it as json.

Can something like this be done? I know my samples can be ridiculous. Because I had no idea.
