Overview of this book

Visualforce is a framework that allows developers to build sophisticated, custom user interfaces that can be hosted natively on the Force.com platform. The Visualforce framework includes a tag-based markup language, similar to HTML that is used to write the Visualforce pages and a set of controllers that are used to write business logic to the Visualforce pages. Visualforce Development Cookbook provides solutions to a variety of challenges faced by Salesforce developers and demonstrates how easy it is to build rich, interactive pages using Visualforce. Whether you are looking to make a minor addition to the standard page functionality or override it completely, this book will provide you with the help you require throughout. You will start by learning about the simple utilities and will build up to more advanced techniques for data visualization and to reuse functionality. You will learn how to perform various tasks such as creating multiple records from a single page, visualizing data as charts, using JavaScript to enhance client-side functionality, building a public website, and making data available to a mobile device. With an interesting chapter on tackling common issues faced while developing Visualforce pages, the book provides lots of practical examples to enhance and extend your Salesforce user interface.

Preface

Introduction


When Visualforce pages utilize a controller extension or custom controller, they can retrieve additional records via SOQL queries. This allows pages to manage more than one record, regardless of the record sObject types or whether there is any relationship between the records.

Note

Salesforce Object Query Language (SOQL) allows information to be retrieved from the Salesforce database based on supplied criteria. It has an SQL-like syntax but does not support advanced operations such as wildcard field lists.

In this chapter, we will explore a number of scenarios to manage multiple records on a single page, ranging from a single record and its parent to a deep and wide hierarchy.

We will also see how Visualforce can be used to present details of a collection of records in response to user-specified criteria, in order to search for existing matches before creating a new record or to produce a custom report page.
