View and View Model

Step 2: Create Controller add Action which will return the JSON result, My Controller is as below. Note I have added action which return the JSON result.
  1. using DropdownGrid.Models;  
  2. using System;  
  3. using System.Web.Mvc;  
  4. namespace DropdownGrid.Controllers  
  5. {  
  6.     public class JSONANDAJAXDemoController: Controller  
  7.     {  
  8.         public ActionResult Index()  
  9.         {  
  10.             MyMultipleUpdateViewModel obj = new MyMultipleUpdateViewModel();  
  11.             obj.myTest1ViewModel = new MyTest1ViewModel();  
  12.             obj.myTest1ViewModel.MyTestUpdate = "Test1";  
  13.             obj.myTest2ViewModel = new MyTest2ViewModel();  
  14.             obj.myTest2ViewModel.MyTestUpdate = "Test2";  
  15.             return View(obj);  
  16.         }  
  17.         public JsonResult GetJSONObject()  
  18.         {  
  19.             MyMultipleUpdateViewModel obj = new MyMultipleUpdateViewModel();  
  20.             obj.myTest1ViewModel = new MyTest1ViewModel();  
  21.             obj.myTest1ViewModel.MyTestUpdate = "Test1" + DateTime.Now.ToString();  
  22.             obj.myTest2ViewModel = new MyTest2ViewModel();  
  23.             obj.myTest2ViewModel.MyTestUpdate = "Test2" + DateTime.Now.ToString();  
  24.             return Json(obj, JsonRequestBehavior.AllowGet);  
  25.         }  
  26.     }  
  27. }  
Step 3: Include jQuery and AJAX in your project.

Case 4

JSON action

This is my AJAX call to JSON action.
  1. <script type="text/javascript">  
  2. $(document)  
  3.     .ready(function ()  
  4.     {  
  5.         $('#Submit')  
  6.             .click(function ()  
  7.             {  
  8.                 $.ajax(  
  9.                 {  
  10.                     url: '/JSONANDAJAXDemo/GetJSONObject/',  
  11.                     type: 'get',  
  12.                     dataType: "json",  
  13.                     success: successFunc,  
  14.                     error: errorFunc  
  15.                 });  
  16.   
  17.                 function successFunc(data)  
  18.                 {  
  19.                     $("#Div1")  
  20.                         .html('')  
  21.                     $("#Div1")  
  22.                         .html("Call using JSON Object : " + data.myTest1ViewModel.MyTestUpdate);  
  23.                     $("#Div2")  
  24.                         .html('')  
  25.                     $("#Div2")  
  26.                         .html("Call using JSON Object : " + data.myTest2ViewModel.MyTestUpdate);  
  27.                 }  
  28.   
  29.                 function errorFunc()  
  30.                 {  
  31.                     alert('MVC controller call failed.');  
  32.                 }  
  33.             });  
  34.     });  
  35. </script>  
Note: You may add table or design in any form of HTML.

  1. <div id="Div1"> Initial State : @Model.myTest1ViewModel.MyTestUpdate </div>  
  2. <div id="Div2"> Initial State : @Model.myTest2ViewModel.MyTestUpdate </div>  
  3. <input type="submit" value="Load Json Object Data" id="Submit" />
