Populating List with User Roles

I'm Trying to populate a DropDownList With Roles from my AspNetRoles table, in a Register form. When i hit Create i get this error :

There is no ViewData item of type 'IEnumerable' that has the key 'Name'.

AccountController.cs

[AllowAnonymous]
public ActionResult Register()
{
ViewBag.Name = new SelectList(context.Roles, "Name", "Name");
return View();
}
//
// POST: /Account/Register
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task Register(RegisterViewModel model)
{
if (ModelState.IsValid)
{
var user = new ApplicationUser { UserName = model.Email, Email = model.Email };
var result = await UserManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
//Assign Role to user Here
result= await this.UserManager.AddToRoleAsync(user.Id, model.UserRoles);
//Ends Here
await SignInManager.SignInAsync(user, isPersistent:false, rememberBrowser:false);
// For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771
// Send an email with this link
// string code = await UserManager.GenerateEmailConfirmationTokenAsync(user.Id);
// var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
// await UserManager.SendEmailAsync(user.Id, "Confirm your account", "Please confirm your account by clicking here");
return RedirectToAction("Index", "Home");
}
AddErrors(result);
}
// If we got this far, something failed, redisplay form
return View(model);
}

@using System.Web.Mvc.Html
@model YCS.Models.RegisterViewModel
@{
ViewBag.Title = "Register";
}
@ViewBag.Title.
@using (Html.BeginForm("Register", "Account", FormMethod.Post, new { @class = "form-horizontal", role = "form" }))
{
@Html.AntiForgeryToken()
Create a new account.
@Html.ValidationSummary("", new { @class = "text-danger" })
class="form-group">
@Html.LabelFor(m => m.Email, new { @class = "col-md-2 control-label" })
class="col-md-10">
@Html.TextBoxFor(m => m.Email, new { @class = "form-control" })

class="form-group">

@Html.LabelFor(m => m.Password, new { @class = "col-md-2 control-label" })

class="col-md-10">

@Html.PasswordFor(m => m.Password, new { @class = "form-control" })

Hi Shriya,

Is it worked?

Hi Shriya,

Kindly check your context.Roles has Name Property. The Error is occuring due to Name property is not exist in your context.Roles result. Please check whether the Name property is exist or not.

ViewBag.Name = new SelectList(context.Roles, "Name", "Name");

Hello Ramesh

The line of code is being Underlined: 'SelectListItem' does not contain a constructor that takes 3 arguments.

Hi Shiriya,

Please modify the below code and try again,

ViewBag.Name = new SelectListItem(context.Roles, "Name", "Name");

Hi Shiriya,

Please modify the below line in your html source,

@Html.DropDownList("Name", (IEnumerable)ViewBag.Name, "Select ...")
