    copied!<p>I'm trying to create an admin section to manage users using .net MVC3 in vs 2010. I've figured out how to create and edit new users and roles separately. But I am struggling to figure out how to add roles when I create or edit a new user. This is as far as I've gotten:</p> <p>In my Model:</p> <pre><code>public class UserModel { [Required] [Display(Name = "User name")] public string UserName { get; set; } [Required] [DataType(DataType.EmailAddress)] [Display(Name = "Email address")] public string Email { get; set; } [Required] [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)] [DataType(DataType.Password)] [Display(Name = "Password")] public string Password { get; set; } [DataType(DataType.Password)] [Display(Name = "Confirm password")] [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")] public string ConfirmPassword { get; set; } } public class IndexViewModel { public IEnumerable&lt;UserModel&gt; Users { get; set; } public IEnumerable&lt;string&gt; Roles { get; set; } } </code></pre> <p>In my Controller</p> <pre><code>public ActionResult Index() { return View( new IndexViewModel { Users = Membership.GetAllUsers().Cast&lt;MembershipUser&gt;().Select(x =&gt; new UserModel { UserName = x.UserName, Email = x.Email, }), Roles = Roles.GetAllRoles() }); } </code></pre> <p>And in the View:</p> <pre><code>@model IEnumerable&lt;BBmvc.Areas.Tools.Models.IndexViewModel&gt; //... @foreach (var item in Model) { foreach (var user in item.Users) { &lt;tr&gt; &lt;td&gt; @Html.DisplayFor(modelItem =&gt; user.UserName) &lt;/td&gt; &lt;td&gt; @Html.DisplayFor(modelItem =&gt; user.Email) &lt;/td&gt; &lt;td&gt; @Html.DisplayFor(modelItem =&gt; user.Password) &lt;/td&gt; &lt;td&gt; @Html.DisplayFor(modelItem =&gt; user.ConfirmPassword) &lt;/td&gt; &lt;td&gt; @Html.ActionLink("Edit", "Edit", new { /* id=user.PrimaryKey */ }) | @Html.ActionLink("Details", "Details", new { /* id=user.PrimaryKey */ }) | @Html.ActionLink("Delete", "Delete", new { /* id=user.PrimaryKey */ }) &lt;/td&gt; &lt;/tr&gt; } } </code></pre> <p>I am seeing this error: </p> <blockquote> <p>The model item passed into the dictionary is of type 'BBmvc.Areas.Tools.Models.IndexViewModel', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable</p> </blockquote> <p>I'm confused. Am I on the right track? Right now I'm simply trying to get the roles to display on the page ... eventually I need them to be filtered for each user so that only the roles a user is in will be listed.</p> <p><strong>EDIT:</strong> The answer below fixed the viewmodel problem I was having. The ultimate solution to displaying roles for each user wasn't that involved. I added a list to the UserModel:</p> <pre><code>public IEnumerable&lt;string&gt; UserRoles { get; set; } </code></pre> <p>Filled it in the Controller:</p> <pre><code> public ActionResult Index2() { var model = Membership.GetAllUsers().Cast&lt;MembershipUser&gt;().Select(x =&gt; new UserModel { UserName = x.UserName, Email = x.Email, UserRoles = Roles.GetRolesForUser(x.UserName) }); return View(model); } </code></pre> <p>And then displayed it in the view:</p> <pre><code>@foreach (var item in Model) { &lt;tr&gt; &lt;td&gt; @Html.DisplayFor(modelItem =&gt; item.UserName) &lt;/td&gt; &lt;td&gt; @Html.DisplayFor(modelItem =&gt; item.Email) &lt;/td&gt; &lt;td&gt; @foreach (var role in item.UserRoles) { @role } &lt;/td&gt; &lt;td&gt; @Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) | @Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) | @Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ }) &lt;/td&gt; &lt;/tr&gt; </code></pre> <p>}</p> <p>Thanks to everyone!</p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
