Hi all,

I want to display the JSON response values in VF page. I tried the below code. But it simply displaying the columns not the values. Please anyone suggest me some idea how to display the response in VF page.

Here is my controller
global class CanvasController{

public Integer ItemId{get;set;}
public String name{get;set;}
public List<Items> dr{get;set;}

public CanvasController(){


public void requestM(){

    String url = 'http://api.walmartlabs.com/v1/feeds/specialbuy?apikey=5amzkrmy235zddjwmu785hf8&categoryId=3944';

    HttpRequest req = new HttpRequest();

    Http http = new Http();
    HttpResponse res = http.send(req);
    String responseBody = res.getBody();
    ResCls resItem = (ResCls)JSON.deserialize(responseBody, ResCls.class);
    List<Items> rl = resItem.items;
    List<Items> dr = new List<Items>();
    for(Items it:rl){
        system.debug('Item Name: ' + it);
        ItemId = it.ItemId;
        name = it.Name;
        system.debug('ItemId: ' + it.ItemId);
        system.debug('Name: ' + it.Name);
   system.debug('List: ' + dr);

public class ResCls{
    List<Items> items;
public class Items{

public Integer ItemId{get;set;}
public Integer ParentItemId{get;set;}
public String Name{get;set;}
public Double SalePrice{get;set;}

        <apex:column headerValue="Item id"><apex:outputText value="{!dd.ItemId}"/></apex:column>
        <apex:column headerValue="Name"><apex:outputText value="{!dd.name}"/></apex:column>
        <apex:column headerValue="upc"><apex:outputText value="{!dd.Upc}"/></apex:column>
