How to edit a user in ASP.NET Identity

Question

I am new to the ASP.NET Identity framework and I am trying to do some things. What I want to do is to edit the user who has already register and then update the user details

Answer 1

Create a dbcontext object "context" and you also need to create a model class "UserEdit" and include those fields in it which you wants to edit.

private ApplicationDbContext context = new ApplicationDbContext();
// To view the List of User 
 public ActionResult ListUsers ()
        {
            return View(context.Users.ToList());
        }

public ActionResult EditUser(string email)
        {
            ApplicationUser appUser = new ApplicationUser();
            appUser = UserManager.FindByEmail(email);
            UserEdit user = new UserEdit();
            user.Address = appUser.Address;
            user.FirstName = appUser.FirstName;
            user.LastName = appUser.LastName;
            user.EmailConfirmed = appUser.EmailConfirmed;
            user.Mobile = appUser.Mobile;
            user.City = appUser.City;


            return View(user);
        }

    [HttpPost]
    public async Task EditUser(UserEdit model)
    {


        if (!ModelState.IsValid)
        {
            return View(model);
        }
        var store = new UserStore(new ApplicationDbContext());
        var manager = new UserManager(store);
        var currentUser = manager.FindByEmail(model.Email);
        currentUser.FirstName = model.FirstName;
        currentUser.LastName = model.LastName;
        currentUser.Mobile = model.Mobile;
        currentUser.Address = model.Address;
        currentUser.City = model.City;
        currentUser.EmailConfirmed = model.EmailConfirmed;
        await manager.UpdateAsync(currentUser);
        var ctx = store.Context;
        ctx.SaveChanges();
        TempData["msg"] = "Profile Changes Saved !";
        return RedirectToAction("ListUser");
    }

// for deleting a user

public ActionResult DeleteUser(string id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            var user = context.Users.Find(id);
            if (user == null)
            {
                return HttpNotFound();
            }
            return View(context.Users.Find(id));
        }


        public async Task UserDeleteConfirmed(string id)
        {
            var user = await UserManager.FindByIdAsync(id);

            var result = await UserManager.DeleteAsync(user);
            if (result.Succeeded)
            {
                TempData["UserDeleted"] = "User Successfully Deleted";
                return RedirectToAction("ManageEditors");
            }
            else
            {
                TempData["UserDeleted"] = "Error Deleting User";
                return RedirectToAction("ManageEditors");
            }
        }

Below is the View for ListUser:

@model IEnumerable

@{
    ViewBag.Title = "ListUsers";
}


    

        

            
@ViewBag.Message
        
        

            
ManageEditors


            
                @{ int sno = 1;
                   foreach (var item in Model)
                {
                    
                }
}
            

                

                    

                        S.No.
                    
                    

                        Email
                    
                    

                     EmailConfirmed
                    

                    

                       FirstName
                    
                    

                       LastName
                    
                    

                        Mobile
                    
                    

                

                        

                         @(sno++)
                        
                        

                            @Html.DisplayFor(modelItem => item.Email)
                        
                        

                            @Html.DisplayFor(modelItem => item.EmailConfirmed)
                        

                        

                            @Html.DisplayFor(modelItem => item.FirstName)
                        
                        

                            @Html.DisplayFor(modelItem => item.LastName)
                        
                        

                            @Html.DisplayFor(modelItem => item.Mobile)
                        
                        

                            @Html.ActionLink("Edit", "EditUser", new { email=item.Email})
                            @Html.ActionLink("Delete", "DeleteUser", new { id = item.Id })
                        
                    


        
    

// below is my UserEdit Model

 public class UserEdit
    {
        [Display(Name = "Email")]
        public string Email { get; set; }

        [Required]
        [Display(Name = "First Name")]
        public string FirstName { get; set; }

        [Required]
        [Display(Name = "Last Name")]
        public string LastName { get; set; }


        [Display(Name = "Mobile")]
        public string Mobile { get; set; }


        [Display(Name = "Address")]
        public string Address { get; set; }


        [Display(Name = "City")]
        public string City { get; set; }

        public bool EmailConfirmed { get; set; }
    }

Hope this help you :)
