Display pageBlock Buttons in bottom

Biswajeet November 1, 2017 No Comments

We use location attribute in pageBlockButtons to display pageblock button in bottom alone. The possible values of location attribute are “top”, “bottom” and “both”. If not specified, this value defaults to “both”.

Here I’m using location="bottom" to display buttons in bottom only.

<apex:page standardController="Account">
	<apex:form>
		<apex:pageBlock mode="edit">
			<apex:pageBlockButtons location="bottom">
				<apex:commandButton action="{!Save}" value="Save"/>
				<apex:commandButton action="{!Cancel}" value="Cancel" immediate="true" />
			</apex:pageBlockButtons>
			<apex:pageBlockSection columns="2" title="Account Information">
				<apex:inputField value="{!Account.Name}"  required="true"/>
				<apex:inputField value="{!Account.Phone}"/>
			</apex:pageBlockSection>
		</apex:pageBlock>
	</apex:form>
</apex:page>

Note: If a pageBlock header facet is defined, the facet overrides the buttons that would normally appear at the top of the page block. Likewise if a pageBlock footer facet is defined, the facet overrides the buttons that would normally appear at the bottom of the page block.

Use Lightning Component in Visualforce Page

Biswajeet October 28, 2017 No Comments

In Winter’16 the ability to add Lightning Components to Visualforce pages was made generally available. This powerful new feature allows you to reuse existing Lightning Components or design and implement new features as Lightning Components with the flexibility to use of them in new or existing Visualforce pages.

This article is to show you how to add Lightning components to Visualforce pages.

Let’s create a lightning component named “HelloWorld.cmp” either through developer console or through your IDE. Use the below mentioned code in your lightning component.

Lightning Component:

<!--HelloWorld-->
<aura:component implements="force:appHostable">
    <div>
        Hello World    
    </div>
</aura:component>

Now we use this Lightning component in a Lightning app. For this I recommend you to create a new Lightning app, let’s call it “HelloWorldApp.app” and use the above lightning component “HelloWorld.cmp” in this app.

Lightning App:

<!--HelloWorldApp-->
<aura:application extends="ltng:outApp" access="global">
    <aura:dependency resource="c:HelloWorld"/>
</aura:application>

In above Lightning app, I have used aura application access as global, so that it can be used anywhere in Salesforce organization like Visualforce. Extending ltng:outApp indicates that any component defined in this application can be used on Visualforce page.

Now create a VisualForce page which would display this lightning component. VisualForce page would provide the interface where we can view the lightning component that we are going to use in the page. Use the below code in your VF page.

In my Visualforce page, we have a special include apex:includeLightning for Lighting. We also need to create a container div id="LightningContainer" for the Lightning components to appear in.

Visualforce Page:

<apex:page >
    <apex:includeLightning />
    <div style="width:100%;height:100px;" id="LightningContainer" />
    
    <script>
        $Lightning.use("c:HelloWorldApp", function() {
            $Lightning.createComponent("c:HelloWorld", { },
            "LightningContainer",
            function(cmp) {
                console.log('Component created');
            });
        });
    </script>
</apex:page>

Note: If your Org has a namespace, then in Visualforce page we have to mention the namespace for Lightning app as yournamespace:HelloWorldApp instead of c:HelloWorldApp.

Here is the Visualforce page output:

Call Multiple Apex Methods in Lightning Controller

Biswajeet October 27, 2017 1 Comment

Apex Controller:

public with sharing class AccountController {

    @AuraEnabled
    public static Account getAccount(Id accountId) {
        Account acc = new Account();
        acc = [SELECT Id, Name, Description FROM Account WHERE Id=:accountId];
        return acc;
    }
    
    @AuraEnabled
    public static List<Attachment> getAttachments(Id parentId) {                            
        List<Attachment> listAttachment = new List<Attachment>();
        listAttachment = [SELECT Id, Name FROM Attachment WHERE ParentId = :parentId];
        return listAttachment;
    }
}

Lightning Component:

<aura:component controller="AccountController" implements="force:appHostable,flexipage:availableForAllPageTypes,force:hasRecordId" access="global">
    <aura:attribute name="recordId" type="Id" />
    <aura:attribute name="acc" type="Account"/>
    <aura:attribute name="attachments" type="Attachment[]"/>
    <aura:handler name="init" value="{!this}" action="{!c.doInit}" />
    
    <div>
        <div>{!v.acc.Name}</div>
        <div>{!v.acc.Description}</div>
        
        <ul>
            <aura:iteration items="{!v.attachments}" var="a">
                <li>
                    <a target="_blank" href="{! '/servlet/servlet.FileDownload?file=' + a.Id }">{!a.Name}</a>
                </li>
            </aura:iteration>
        </ul>
    </div>

Lightning Controller:

({
    doInit : function (component) {
    var action = component.get('c.getAccount');
    action.setParams({
        "accountId": component.get("v.recordId")
    });
        
	action.setCallback(this, function(response) {
        var state = response.getState();
        if (state == "SUCCESS") {
            var account = response.getReturnValue();
            component.set("v.acc", account);
        }
    });
        
    var action2 = component.get('c.getAttachments');
    action2.setParams({
        "parentId": component.get("v.recordId")
    });
        
	action2.setCallback(this, function(response) {
        var state = response.getState();
        if (state == "SUCCESS") {
            var attachments = response.getReturnValue();
            component.set("v.attachments", attachments);
        }
    });
    $A.enqueueAction(action);
    $A.enqueueAction(action2);
}
})

Enum in Apex

Biswajeet October 20, 2017 No Comments

An enum is an abstract data type with values that each take on exactly one of a finite set of identifiers that you specify. Enums are typically used to define a set of possible values.

Although each value corresponds to a distinct integer value, the enum hides this implementation so that you don’t inadvertently misuse the values, such as using them to perform arithmetic. After you create an enum, variables, method arguments, and return types can be declared of that type. Apex provides built-in enums, such as LoggingLevel, and you can define your own enum.

To define an enum, use the enum keyword in your declaration and use curly braces to demarcate the list of possible values.

For Example:
The following code creates an enum called Season:

public enum Season {WINTER, SPRING, SUMMER, FALL}

By creating the enum Season, you have also created a new data type called Season. You can use this new data type as you might any other data type.

For Example:

Season e = Season.WINTER;

Season CheckSeason(Season e) {
    if (e == Season.SUMMER){
		return e;
	}
}

Enum Methods:
All Apex enums, whether user-defined enums or built-in enums, have the following common method that takes no arguments.

values : This method returns the values of the Enum as a list of the same Enum type. Each Enum value has the following methods that take no arguments.
name : Returns the name of the Enum item as a String.
ordinal : Returns the position of the item, as an Integer, in the list of Enum values starting with zero.
Note: Enum values cannot have user-defined methods added to them.
For Example:

Integer i = StatusCode.DELETE_FAILED.ordinal();
String s = StatusCode.DELETE_FAILED.name();
List<StatusCode> values = StatusCode.values();
