🌟 Getting Started with Visualforce: What, Why, and How?

---

Welcome to the first post of my Salesforce Visualforce Learning Series, where I document my daily journey of mastering Visualforce and Apex through hands-on projects, real debugging, and practical examples. Whether you're just getting started or refreshing your basics, this blog is written with simplicity and clarity in mind. Let's dive in!

🔍 What is Visualforce?

Visualforce is a component-based UI framework from Salesforce that allows developers to build custom user interfaces using HTML-style tags and optional Apex controllers. It was introduced in 2008 and has been widely used across classic Salesforce applications.

It uses:

• Tag-based markup (<apex:page>, <apex:form>, <apex:outputText>, etc.)

• Apex controller logic for dynamic behavior and database interaction

📄 Why Learn Visualforce?

Even though Lightning Web Components (LWC) is the modern way to build UI in Salesforce, Visualforce is still essential for:

• Maintaining and updating legacy apps

• Creating admin-friendly internal tools quickly

• PDF generation or complex tabular layouts

• Deep integration with standard Salesforce UI and workflows

⚙️ How Does Visualforce Work?

Here are 3 beginner-friendly Visualforce examples:

✅ 1. Basic Hello World Page

<apex:page>
    <h1>Hello Visualforce!</h1>
</apex:page>

✅ 2. Visualforce Page with Controller

<apex:page controller="MyController">
    <h2>Hello {!name}!</h2>
</apex:page>

public class MyController {
    public String name { get; set; }
    public MyController() {
        name = 'Visualforce Developer';
    }
}

✅ 3. Using a Form to Save Data

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