I have 2 roles Admin and Donor

Upon registration any user must be added to the Donor role. How do I achieve this with identity and mvc5.

C#

[HttpPost]
        [AllowAnonymous]
        [ValidateAntiForgeryToken]
        public async Task<ActionResult> Register(RegisterViewModel model)
        {
            if (ModelState.IsValid)
            {
                var user = model.GetUser();
                var result = await UserManager.CreateAsync(user, model.Password);
                UserManager.AddToRole(user.UserName, "User");
                if (result.Succeeded)
                {
                    return RedirectToAction("Index", "Account");
                }

            }

            // If we got this far, something failed, redisplay form
            return View(model);
        }

I getthe following error System.InvalidOperationException: UserId not found.

Thank you. It does assign the role to the user. What I need to do now is navigate to a specific view with a layout for that role. Any ideas

Most Welcome !! use multiple layout pages and write logic in _ViewStart file, for more..http://stackoverflow.com/questions/8419826/dynamic-change-viewstart-layout-path-in-mvc-3

Maybe you can help me with my other question??

I have a drop down with certain values

<pre lang="cs">@using (Html.BeginForm())
{

@Html.DropDownList("Animal Type",
new SelectList((System.Collections.IEnumerable) ViewData["Animal"], "animal_type"))

}</pre>

my controller action for that method is

<pre lang="sql">[HttpGet]
public ActionResult create()
{
var animal = from x in db.Animals
select x.animal_type;
ViewData["Animal"] = animal;
return View();
}</pre>

After selecting a value from the drop down it should display the specific partial view on the same view

First check for result, then only add role. That mean change the position of UserManager.AddToRole like:

C#

var user = model.GetUser();
var result = await UserManager.CreateAsync(user, model.Password);
if (result.Succeeded)
    result = UserManager.AddToRole(user.Id, "User");

You can add multiple roles too if you have a list of roles.

C#

foreach(var role in roles)
{
   var isInRole = await UserManager.IsInRoleAsync(userid, role)
   if(!isInRole)
   {
      await UserManager.AddToRoleAsync(userid, role);
   }
}
