    win.show();
});

User Login InterFace. Here user input userid and password click to login.

using extjs Create Login page and add,edit,update record from database.
public bool Post(UserLogin obj)
        {
            bool success;

            var result = db.UserLogin.FirstOrDefault(x => x.UserEmail == obj.UserEmail && x.Password == obj.Password);
            if (result != null)
            {
                success = true;
              
            }
            else
            {
                 success =false;
             
            }
            return success;
        }

Login success click ok go to dashboard page.

using extjs Create Login page and add,edit,update record from database.
 

Dashboard.cshtml

This is dashboard page output

using extjs Create Login page and add,edit,update record from database.

This  method get userlist . and we can use paging and shorting.

public class ModelList
    {
        public IEnumerable<UserLogin> Users { get; set; }
        public int TotalCount { get; set; }
    } 
public ModelList Get(int start, int limit, string sort)
        {
            
            ModelList result = new ModelList();
            var data = db.UserLogin.AsQueryable();
            result.Users = data.OrderBy(x => x.UserName).Skip(start).Take(limit).ToList();
            result.TotalCount = data.Count();
            return result;
        } 

This is dashboard user list output.

using extjs Create Login page and add,edit,update record from database.

 This is add new user form  output.

using extjs Create Login page and add,edit,update record from database.

  This is edit user form Output.

using extjs Create Login page and add,edit,update record from database.

This method use for add,update user.

public void Post(UserLogin obj)
        {
            var original = db.UserLogin.Find(obj.UserId);
            if (original != null)
            {
                original.UserName = obj.UserName;
                original.UserEmail = obj.UserEmail;
                original.PhoneNumber = obj.PhoneNumber;
                original.Password = obj.Password;
                original.Address = obj.Address;
            }
            else
            {
                db.UserLogin.Add(obj);
            }

            db.SaveChanges();
        } 
This method use for delete user.d
public void Delete(int id)
        {
            var original = db.UserLogin.Find(id);
            if (original != null)
            {
                db.UserLogin.Remove(original);
            }

            db.SaveChanges();
        }
