My Controller Code

C#

// GET: api/Courses
        public IQueryable<object> GetCourses()
        {
            return db.Courses.Select(
               o => new
               {
                   CourseID = o.CourseID,
                   CourseName = o.CourseName,
                  IsActive = o.IsActive
               });
        }

My JSON data being returned

C#

[{"CourseID":1,"CourseName":"Beauty Therapy","IsActive":true},{"CourseID":2,"CourseName":"Software Development","IsActive":true},{"CourseID":3,"CourseName":"Bookkeeping and Accounting","IsActive":true}]

What I have tried:

I followed the example on Telerik's website http://demos.telerik.com/kendo-ui/grid/mvvm

Heyy While updating the code format, I guess I missed some code. Can you please post and update the question with the data.
I apologize for this.

Sorry Passion4Code, but thanks for the interest. I finally got help from another guru and I will post it below

I finally got this fixed. The structure of my solution is such that it has a WebAPI and a Web app. So in the WebApiConfig.cs file I added the line in bold and it worked.

C#

public static void Register(HttpConfiguration config)
        {
            // Web API configuration and services

            config.EnableCors();

            // Web API routes
            config.MapHttpAttributeRoutes();

            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

            
        }
