Question

I am wondering how to check in an Action, from which View I made POST to it.
So after the action is complete I can make a return back to that same View.

Like:

if (enteredfromView1)
{
    return RedirectToAction("View1","Controller");
}
else
    return RedirectToAction ("View2","Controller");

You can use the Request.UrlReferrer to implement this.

public ActionResult TryMeOut()
{
   TempData["ReturnPath"] = Request.UrlReferrer.ToString();
   //return your users to the correct view.
}
