Lightning in Salesforce – Part 3

Lightning in Salesforce – Part 3

In the previous post we learn how to use client side controller in lightning. In this post we will continue this with how to take input from user and process them between controller and save user inputs.

In lightning we have some native tags to get user inputs (Same as Visualforce tag or general HTML tag)

<ui:inputText aura:id="expname" label=" Account  Name"

value="{!v. account.Name}" required="true"/>

<ui:inputNumber aura:id="amount" label="Amount"

value="{!v. account.Amount__c}" required="true"/>

<ui:inputDate aura:id="expdate" label="Meeting  Date"

value="{!v. account.Date__c}" displayDatePicker="true"/>

<ui:inputCheckbox aura:id="reimbursed" label="Reimbursed?"


<ui:button label=”Create Account” press=”{!c.clickCreateRecord}”/>

Then in the button click we will pass this data into controller for processing

clickCreateExpense: function(component, event, helper)

and now we can use helper to do some processing.

helper.createExpense(component, account); //account is instance of account

But now to save this we need to call apex controller. In apex we will use this format. So to call apex methods in Lightning we will follow this format


public static List<account > getaccount()

Use @Auraenabled to access this method in Lightning. All method must be static so it’s stateless communication and faster then Visualforce Apex communication.


To get data from apex in lightning

// Load expenses from Salesforce

doInit: function(component, event, helper) {

// Create the action

var action = component.get("c.getaccount");

// Add callback behavior for when response is received

action.setCallback(this, function(response) {

var state = response.getState();

if (component.isValid() && state === "SUCCESS") {

component.set("v.account", response.getReturnValue());


else {

console.log("Failed with state: " + state);



// Send action off to be executed



We will follow this approach to pass data in apex controller

createAccount: function(component, account) {

var action = component.get("c.saveAccount");


"account": account


action.setCallback(this, function(response){

var state = response.getState();

if (component.isValid() && state === "SUCCESS") {

var accounts = component.get("v.accounts");


component.set("v.accounts", accounts);





Here we use setparams to pass the parameter in apex and then use them in our code. So now we have good idea of how to pass data between Lightning and apex. So the last point in our journey is Events.

Event is used to pass data between one component and another.

In the Developer Console, select File | New | Lightning Event, and name the event “testEvent”

var createEvent = component.getEvent("testExpanse");

createEvent.setParams({ "account": newAccount });;

We will use fire() to fire the event and

 var newAccout = event.getParam("account"); 

is used to catch the events.

So here we cover all basic and starting points for development in sLightning. In my next post we will cover some advance uses of Lightning.

Do you have anything to say or want to add anything useful. Please share them in comments.

Lightning in Salesforce – Part 2

Lightning in Salesforce – Part 2

In the previous post we have discussed what is Lightning, Lightning app and some other basic details. In this post we will continue with Lightning component.

To create Lightning component first go to developer console select File | New | Lightning Component to create a new Lightning component. In the New Lightning Bundle panel, enter HelloWorld for the component name, and click Submit.Component


Now add this lightning component in the lightning app to view this in browser. A component is a bundle that includes a definition resource, written in markup, and may include additional, optional resources like a controller, stylesheet, and so on. A resource is sort of like a file, but stored in Salesforce rather than on a file system.

We will write our complete code in the lightning components.

Now we will learn to add attribute and expression this is a same process which we use in visual force components.

<c:helloMessage message="You look nice today."/>

Here message is an attribute and we will display it using component.


<aura:attribute name="message" type="String"/>

Hello! {!v.message}


This is a component body (looks similar to Visualforce component isn’t it).

Note: to display data we use v. expression format and this will remain same in all places. V is something called a value provider. Value providers are a way to group, encapsulate, and access related data. An expression is basically a formula, or a calculation, which you place within expression delimiters (“{!” and “}”). So, expressions look like the following:



You can also use labels and other text in expression

{!$Label.c.Greeting + v.message}

There are a number of different attribute types.

  1. Primitives data types, such as Boolean, Date, DateTime, Decimal, Double, Integer, Long, or String. The usual suspects in any programming language.
  2. Standard and custom Salesforce objects, such as Account, MyCustomObject__c.
  3. Collections, such as List, Map, and Set.
  4. Custom Apex classes.
  5. Framework-specific types, such as Aura.Component, or Aura.Component[].


Now we will learn how to use controllers.

Lightning component work on View-Controller-Controller-Model, or perhaps View-Controller-Controller-Database. Here two controller refer, one client side controller (JavaScript) and other is server side controller (Apex).

<ui:button label="You look nice today." press="{!c.handleClick}"/>

So when we click this button an event will fire (Same as Visual force) but instead of controller method we will first call client side controller or JavaScript controller.


handleClick: function(component, event, helper) {

var btnClicked = event.getSource();         // the button

var btnMessage = btnClicked.get("v.label"); // the button's label

component.set("v.message", btnMessage);     // update our message



This is the JavaScript controller format. Here event is which start this process. Component contains information related to the component in which this event is fired and helper is as name suggests a helper method which we can call multiple time in component.

handleClick2: function(component, event, helper) {

var newMessage = event.getSource().get("v.label");

component.set("v.message", newMessage);


handleClick3: function(component, event, helper) {

component.set("v.message", event.getSource().get("v.label"));


You can define multiple method but you need to separate them using comma. You can also use JavaScript debugging tools like console.log here to debug the application. In the next post we will learn how to take input from users and pass them in controllers.

Lightning in Salesforce – Part 1

Lightning in Salesforce – Part 1

We all are aware of Lighting and if not then we should. Because with every release Salesforce giving more focus to lightning. Lightning is the future (don’t worry Apex and Visual force will still available).

Those who don’t know what Lightning is for them “Lightning Components is a UI framework for developing web apps for mobile and desktop devices. It’s a modern framework for building single-page applications with dynamic, responsive user interfaces for apps. It uses JavaScript on the client side and Apex on the server side.”



Using lightning you can create Drag and drop component, Stand alone app, Run them in Visualforce page, Run them on other platform using lightning out and appexchange apps too. There are many good posts available on Internet and many resources too. So in this post (of series) I will pick short module and explain them separately. So that user can combine and use them as per their requirement.

So before we start here are some prerequisite:

  1. Create new Developer account.
  2. Enable custom domain and rollout this for user.
  3. Get basic Idea of JavaScript.

Now we will start the modules. In this series of post we will cover following thing.

  1. Lightning App
  2. Lightning component
  3. Attribute and expression
  4. Controller( JavaScript and apex)
  5. Use of helper
  6. Events

First we will start with Lightning App

Open the developer console and Select File | New | Lightning Application to create a new Lightning app. In the New Lightning Bundle panel, enter TestApp for the app name, and click Submit.

App contains the opening and closing tags for a Lightning app, <aura:application>. Between them, we will add all component and Save the app so that we can view the result.



The main items of an app are the following.

  1. When writing markup, you can add a component to an app, but you can’t add an app to another app, or an app to a component.
  2. An app has a standalone URL that you can access while testing, and which you can publish to your users. We often refer to these standalone apps as “”
  3. You can’t add apps to Lightning Experience or Salesforce1—you can only add components.

In the next part we will continue with Lightning components.

Be a Speaker at Dreamforce 16

Hi All, We all know about Dreamforce. Dreamforce is the biggest event of Salesforce in which we get to know lots of things, meet some industry expert and some very great sessions.

Speaking at Dreamforce is a fantastic experience and if you have ever attended, you know that the quality of session speakers is extremely high. If you are thinking for a Dreamforce speaker then here are a few tips and guidelines to give you an idea of what Salesforce looking for.

For 40 minute sessions, Salesforce looking for speakers that:

  1. Have a great story to tell and a passion for sharing your knowledge with others

  2. Provide clear successful use cases, best practices, teachings and how-to’s,

  3. Highlight the ROI and additional benefits your company and team has seen since implementing Salesforce

For our 20 minute theater sessions, Salesforce  looking for speakers that:

  1. Can highlight a tip or trick like “Use this shortcut to save 10 minutes a week”

  2. Tell a great customer success story

  3. Focus and/or highlight a specific feature and how you are using it

  4. A great demo

Here are a few helpful tips for crafting your speaker submission so that you get selected to speak.

  1. Outline your story – what are the key topics or points you want the audience to hear

  2. List and rank your top messages, target personas, target industries.

  3. On the submissions page, be as precise and descriptive as possible.

  4. Also share your past experience and your preference for a 20 or 40 minutes session.

You can do your registration here. All the best :).

Do you have anything to share let us know in comments section.



Connect Salesforce with Part 2

Connect Salesforce with Part 2

Hi All, In my previous post Connect Salesforce with (The Integration series) I have shared how can you create a app and authorize the user from Salesforce.

In this post I am sharing two utility method to create a folder on and upload a file on There are various other methods are available but for starting I have found these two most useful.

So first create a folder in platform you can use this method.

private void createfolder(String fileName, string parentid)
String url = '';
string authorizationHeader = 'Bearer '+Accesstoken ;

HttpRequest req = new HttpRequest();
req.setBody('{"name":"'+fileName+'", "parent":{"id":"0"}}');

Http h = new Http();
Httpresponse resp = h.send(req);


To upload a file in platform use this utility method.


private void uploadFileCode(String folderId,Attachment file,String token){
String boundary = '----------------------------356sdf986eff';
String header = '--'+boundary+'\nContent-Disposition: form-data; name=&quot;file&quot;; filename=&quot;'+fileName+'&quot;;\nContent-Type: application/octet-stream';

String footer = '--'+boundary+'--';
String headerEncoded = EncodingUtil.base64Encode(Blob.valueOf(header+'\r\n\r\n'));
header+=' ';
headerEncoded = EncodingUtil.base64Encode(Blob.valueOf(header+'\r\n\r\n'));
String bodyEncoded = EncodingUtil.base64Encode(file.body);

Blob bodyBlob = null;
String last4Bytes = bodyEncoded.substring(bodyEncoded.length()-4,bodyEncoded.length());
if(last4Bytes.endsWith('==')) {

last4Bytes = last4Bytes.substring(0,2) + '0K';
bodyEncoded = bodyEncoded.substring(0,bodyEncoded.length()-4) + last4Bytes;

String footerEncoded = EncodingUtil.base64Encode(Blob.valueOf(footer));
bodyBlob = EncodingUtil.base64Decode(headerEncoded+bodyEncoded+footerEncoded);
} else if(last4Bytes.endsWith('=')) {
last4Bytes = last4Bytes.substring(0,3) + 'N';
bodyEncoded = bodyEncoded.substring(0,bodyEncoded.length()-4) + last4Bytes;

footer = '\n' + footer;
String footerEncoded = EncodingUtil.base64Encode(Blob.valueOf(footer));
bodyBlob = EncodingUtil.base64Decode(headerEncoded+bodyEncoded+footerEncoded);
} else {
// Prepend the CR LF to the footer
footer = '\r\n' + footer;
String footerEncoded = EncodingUtil.base64Encode(Blob.valueOf(footer));
bodyBlob = EncodingUtil.base64Decode(headerEncoded+bodyEncoded+footerEncoded);

String sUrl = ''+folderId;
HttpRequest req = new HttpRequest();
req.setHeader('Content-Type','multipart/form-data; boundary='+boundary);
req.setHeader('Authorization', 'Bearer '+token);
Http http = new Http();
HTTPResponse res = http.send(req);

These are the two methods which you can use to create a folder and upload file.

Do you have anything to add or like this post or any other thing to share please share them in comments.

Hi All, We all know that’s how costly it is to store data in So we always want to store data in third party so that we can reduce the cost. Thats why today I am sharing the authorization process between Salesforce and in my Integration series.

For this first you need to go to for a Developer account which you can create here.

After successful account creation you need to create an App to get the key and token. You can create an app here.

After creation your app will look like this.




Give your Visualforce page url as redirect URL. Now use the below code to perform the authorization process.


public with sharing class BoxComIntegration {
    //Fetched from URL
    private String code ;
    private string key = 'llpm**************2ks8';
    private string secret = 'LMh**************jCmK2fDHK' ;
    private string redirect_uri = '';
    public BoxComIntegration()
        code = ApexPages.currentPage().getParameters().get('code') ;  
        //Get the access token once we have code
        if(code != '' && code != null)
            AccessToken() ;
    public PageReference BoxAuth()
        PageReference pg = new PageReference(BoxAuthUri (key , redirect_uri)) ;
        return pg ;
    public String BoxAuthUri(String Clientkey,String redirect_uri)
        String key = EncodingUtil.urlEncode(Clientkey,'UTF-8');
        String uri = EncodingUtil.urlEncode(redirect_uri,'UTF-8');
        String authuri = '';
        authuri = ''+
        return authuri;
    public void AccessToken()
        //Getting access token from google
        HttpRequest req = new HttpRequest();
        String messageBody = 'code='+code+'&client_id='+key+'&client_secret='+secret+'&redirect_uri='+redirect_uri+'&grant_type=authorization_code';
        req.setHeader('Content-length', String.valueOf(messageBody.length()));

        Http h = new Http();
        String resp;
        HttpResponse res = h.send(req);
        resp = res.getBody();
         Map<String,object> responseMap =(Map<String,object>)JSON.deserializeUntyped(res.getBody()) ;  
          String token =  String.valueOf(responseMap.get('access_token'));

VF Page:

<apex:page controller="BoxComIntegration">
<apex:form >
    <apex:pageblock > 
        <apex:commandbutton action="{!BoxAuth}" value="Authentication">


Also add two Base URLs in remote site setting. And now you are all set when you run this code you will get access token and using that token you can easily upload, download the files.


Let me know if you like this post. Do you have anything to add in the post. let me know in comments section.

Summer 16 is Here

Hi everyone, As we all are aware Salesforce gives us 3 releases in a year.  Now we have Summer 16 is here and this is Salesforce’s 50 release. So I am also excited as any one else. So I give a read of release notes and found some important points need to remember.  I am sharing them here and if you found any other important update please share them in comments.


  1. Limits increases for the Enterprise, Professional and Unlimited Editions.Find out what’s changed.

 custom apps

If you use a Professional, Enterprise, or Unlimited Edition org, you can now use as many custom apps as you want.

Custom Profiles
Professional Edition orgs can now use up to two custom profiles per license type.
Custom Tabs
If you use a Professional, Enterprise, or Unlimited Edition org, you can now use as many custom tabs as you want.
Field-Level Security
If you use a Professional Edition org with page layouts and add new fields, pay attention to field-level security for your new fields.
Previously existing fields aren’t affected.
Permission Sets
Professional Edition orgs can now use up to two permission sets.
Professional Edition customers now have access to Process Builder, our premier process-automation tool, and can use up to five
processes to automate repetitive tasks.
Record Types
Professional Edition customers can now use up to three record types per object.
Professional, Enterprise, and Unlimited Edition orgs include more sandboxes to use for development, testing, and training.

2. Debug logs now include time zone information for activity timestamps. Previously, you couldn’t tell from a debug log which time zone the logged activities occurred in.

3. View Visualforce Controller Exceptions in Debug Logs
Debug logs now include exceptions thrown by Visualforce controllers. Visualforce controller exceptions have been visible in the Salesforce user interface, but the exceptions looked like successes in the debug log. This feature is available in both Lightning Experience and Salesforce Classic.

4. Set the Page Title in Lightning Experience with the <apex:page> title Attribute
In prior releases of Lightning Experience setting the page title of a Visualforce page had no effect. With this release, you can set the page’s title using the title attribute of the <apex:page> tag. This sets the text used in browser windows, tabs, and bookmarks, and makes using Lightning Experience in multiple tabs a better experience.
You can also set a Visualforce page title by adding a static <title> HTML tag to your page. Although using the page’s title attribute is usually preferred, the treatment of the page title is the same.
Finally, while it’s not a primary use case, setting the page’s title, using either technique, also affects the page in the Salesforce1 mobile browser app. The page’s title appears in the history stack, and in browser tabs or windows. The page title doesn’t appear in the Salesforce1 downloadable app.

5. Increased Cross-Namespace Limits

Good news! We’ve increased the number of unique, certified namespaces that can be invoked during a single Apex transaction.
Previously, the limit during a single transaction was 10. We’ve removed this limit and added a cumulative cross-namespace limit.
There’s now no limit on the number of certified namespaces that can be invoked in a single transaction. However, the number of operations that can be performed in each namespace must not exceed the per-transaction limits. In place of the former limit, there’s a new limit on the cumulative number of operations that can be made across namespaces in a transaction. This cumulative limit is 11 times the per-namespace limit. For example, if the per-namespace limit for SOQL queries is 100, a single transaction can perform up to 1,100 SOQL queries. In this case, the cumulative limit is 11 times the per-namespace limit of 100.

6. This critical update disables access to Lightning Experience and the Salesforce1 mobile browser app when using Microsoft Internet Explorer version 11.

7. Contacts to Multiple Accounts lets reps associate a single contact with multiple accounts. Every contact needs to be associated with a primary account (the account that appears in Account Name). And now, your reps can associate more accounts with each contact. The primary account represents a direct relationship; the other accounts associated with a contact represent indirect relationships.

8. Secure Confidential Client Information with Salesforce Shield
Salesforce Shield, a trio of security tools to help monitor data access and usage, prevent malicious activity, and encrypt data at rest. Protect your client information with Shield, which includes Event Monitoring, Field Audit Trail, and Platform Encryption.

9.You can now create a sandbox by cloning an existing sandbox rather than using your production org as your source. Save time by populating any type of sandbox with a previously chosen set of data and metadata. (Sandbox templates, which serve a similar
purpose, are available only for Full or Partial Copy sandboxes.) Sandbox-to-sandbox cloning facilitates iterative development, allowing you to freeze development in one sandbox and pick up where you left off in a new one.

Please let me know what you like most in summer 16 and what you still want to see in Salesforce.
