Adding values to the controller action manually - asp.net-mvc

Question

I have a model class that is below
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data.Entity;
namespace MyForms.Models
{
public class Master
{
public int ID { get; set; }
public string ModuleName { get; set; }
public int CreatedBy { get; set; }
public DateTime CreatedDate { get; set; }
public int ModifyBy { get; set; }
public DateTime ModifyDate { get; set; }
public Boolean IsActive { get; set; }
public Boolean IsDeleted { get; set; }
// public virtual ICollection<MasterModule> MasterModules { get; set; }
}
Here in this code I am passing the values through views(textboxes). What are my expections
Module Name is entered through text box and when submit button is clicked
CreatedBy contains the ID of the person who create the module(e.g 1. admin 2. manager)
Created date is automatically added as current Date when submit is clicked
ModifyBy contains the ID of the person who modify (edit) the module(e.g 1. admin 2. manager)
ModifyDate is the curent date when the module is edited
when the module is created is activated always sets to be true.
2 to 6 are settled with coding. Now I want to know how can I handle each situation separetaly.
Currently I am adding all the values manually, I mean through the input box and checkboxes
namespace MyForms.Controllers
{
public class MasterController : Controller
{
//
// GET: /Master/
public ActionResult Index()
{
using (MyFormDemoContext context = new MyFormDemoContext())
{
return View(context.MasterForms.ToList());
}
// return View();
}
public ActionResult Create()
{
return View();
}
[HttpPost]
public ActionResult Create(Master master)
{
try
{
using (MyFormDemoContext context = new MyFormDemoContext())
{
context.MasterForms.Add(master);
context.SaveChanges();
}
return RedirectToAction("Index");
}
catch
{
return View();
}
}
}
}
