This document introduces Visualforce, Salesforce's framework for building custom user interfaces that are hosted natively on Force.com. Visualforce uses the model-view-controller (MVC) pattern and allows developers to leverage standard and custom components, controllers written in Apex, and integration with other web technologies. Visualforce pages can be used to build custom applications, extend and customize Salesforce functionality, and develop for different devices.

Standard
Controllers &
Extensions
Markup & UI

6. Visualforce Markup
 Visualforce tags
• 80+ standard components
• Custom components
 Works with all standard web technologies
including:
• CSS
• JavaScript
• HTML

chatter:
Attributes to define
prefix component
<apex:outputField value = “{!Restaurant__c.Address__c” >
Component
name(examples: Reference field
tables, repeats, (using dot notation)
forms, etc)
Data binding to
objects and class
variables

 Provides access to data
 Logic for handling UI interaction
 Standard Controllers
• Same functionality as standard pages
– Save, delete, field access etc.
 Custom Controllers
• Written in Apex
• Override standard behavior
• Controller Extensions

9. What does that look like in code?
Defined at the
page level
Supports both
standard and
custom objects
<apex:page standardController = “Restaurant__c” extensions =“yelpExtension” >
Use custom
If only using custom controllers,
controller logic
use controller=“controllerName”
to extend
standard
controllers

column
datatable
command button
outputfield
markup

11. Custom Tags
Create your
