Introduction

The Kendo UI supports working with its widget using AngularJS.

This article flows as follows,

Creating an ASP.NET WEB API application.
Creating a Controller.
Testing the REST API
Implementing the Kendo Grid using AngularJS with the REST API.

Creating a ASP.NET WEB API application

Create a WEB API application using an installed web template in visual studio as in the following figures:

Creating model classes

In the Solution Explorer, right click the model folder, select Add, then Class and name it Employee.cs

Code in Employee.cs:

public class Employee
{
public Employee(int EmployeeID, string FirstName, string LastName)
{
this.EmployeeID = EmployeeID;
this.FirstName = FirstName;
this.LastName = LastName;
}
public int EmployeeID { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
}

Creating a Controller

Right click on the Controller folder and add a new WEB API 2- Empty controller as in the following figure 3, in my case I named it EmployeeDetailsController.cs:

Code in EmployeeDetailsController.cs:

[RoutePrefix("api/EmployeeList")]
public class EmployeeDetailsController : ApiController
{
[HttpGet]
[Route("List")]
public HttpResponseMessage EmployeeList()
{
try
{
List<Employee> _emp = new List<Employee>();
_emp.Add(new Employee(1, "Bobb", "Ross"));
_emp.Add(new Employee(2, "Pradeep", "Raj"));
_emp.Add(new Employee(3, "Arun", "Kumar"));
return Request.CreateResponse(HttpStatusCode.OK, _emp, Configuration.Formatters.JsonFormatter);
}
catch (Exception ex)
{
return Request.CreateResponse(HttpStatusCode.OK, ex.Message, Configuration.Formatters.JsonFormatter);
}
}
}

The above employee controller action EmployeeList will return a list of Employees.

Testing the REST API

Test the API using the POSTMAN/Fiddler as in the following figure 4:

API End Point: /api/EmployeeList/List

Type : GET

The API is working fine, now it's ready to consume.

Creating a HTML page

Create a new HTML page in the project.
