Can not populate Kendo grid using a ViewBag instead of a model

I have created a MVC application that uses multiple entities to populate a view using a ViewBag to pass the data.

However I can not seem to get the Kendo UI grid to populate from the ViewBag and I keep getting the following runtime error:

CS0452: The type 'System.Collections.Generic.KeyValuePair<string,string>' must be a reference type in order to use it as parameter 'T' in the generic type or method 'Kendo.Mvc.UI.Fluent.WidgetFactory.Grid<T>(System.Collections.Generic.IEnumerable<T>)'

I believe the issue I am having is from this line of code:

@(Html.Kendo().Grid((Dictionary<string,string>)ViewBag.ApplicationStatuses)

The full Razor code is as follows:

@{
    ViewBag.Title = "TestView";
}

<h2>TestView</h2>


    @(Html.Kendo().Grid((Dictionary<string,string>)ViewBag.ApplicationStatuses).Name("UserDetails").Columns(c =>
    {
        c.Bound(ud => ud.FullName);
        c.Bound(ud => ud.JobTitle);
        c.Bound(ud => ud.Department);
        c.Bound(ud => ud.Email);
        c.Template(
            @<text>
                @Html.ActionLink("User Details", "UserDetails", "User", new { userName = item.UserName }, null)
            </text>
            );
        })
    )

My controller:

 public ActionResult TestView(string userName)
    {
        Dictionary<string, string> statuses = new Dictionary<string, string>();

        foreach (KeyValuePair<Application.Applications, IUser> entry in Application.UserMap)
        {
            IUser user = entry.Value;
            statuses.Add(entry.Key.ToString(), entry.Value.GetUserStatus(userName));
        }

        ViewBag.ApplicationStatuses = statuses;
        ViewBag.UserName = userName;

        return View();
    }

Could anybody explain to me why I am having this issue and what the solution is?

Any help would be very appreciated.

Sorry for the late answer, but I Solved this by changing the logic of my program and using a Model instead. This populated the Grid and gave me easier control over validation. Thank you for your patience.

First of all, done use ViewBag. Create strongly typed viewmodel see this http://www.asp.net/mvc/tutorials/views/dynamic-v-strongly-typed-views

and you can't bind dictionary to kendo like this
