Mastering Visualforce

Visualforce is a powerful markup language within the Salesforce ecosystem that empowers developers to create custom user interfaces, enhancing user experiences and driving user engagement. This chapter delves into the intricacies of mastering Visualforce, covering its fundamental concepts, advanced features, and practical application through examples and a real-world case study.

Introduction to Visualforce

Visualforce serves as a bridge between data and design, enabling developers to create dynamic and responsive user interfaces directly within the Salesforce platform. This markup language allows for the construction of custom pages, components, and forms tailored to specific business requirements.

Basic Visualforce Elements

Visualforce employs a tag-based syntax, resembling HTML, to structure and design interfaces. Essential elements include:

  • <apex:page>: Defines a Visualforce page.
  • <apex:outputText>: Displays text values.
  • <apex:inputField>: Generates input fields for object data.

Example: Consider a Visualforce page for editing contact details:

<apex:page standardController="Contact">
        <apex:inputField value="{!Contact.FirstName}"/>
        <apex:inputField value="{!Contact.LastName}"/>
        <apex:commandButton action="{!save}" value="Save"/>

Custom Controllers and Extensions

Visualforce pages can be enhanced with custom controllers, enabling the execution of Apex logic. Extensions allow the addition of custom behavior to standard controllers.

Example: Extending the contact editing page to include a button that calculates a contact's age:

public class ContactExtension {
    private final Contact c;

    public ContactExtension(ApexPages.StandardController stdController) {
        this.c = (Contact)stdController.getRecord();

    public Integer calculateAge() {
        Date today =;
        Date birthdate = c.Birthdate;
        return birthdate != null ? today.year() - birthdate.year() : null;

Visualforce Components

Components facilitate modular design and reusability in Visualforce. They encapsulate UI elements and behavior, allowing developers to create consistent and efficient interfaces.

Example: Designing a reusable "Task List" component to display tasks related to an account:

    <apex:attribute name="accountId" type="Id" description="Account Id" required="true"/>

    <apex:pageBlock title="Task List">
        <apex:pageBlockTable value="{!relatedTasks}" var="task">
            <apex:column value="{!task.Subject}"/>
            <apex:column value="{!task.Status}"/>
