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.

One task that users often find unwieldy when implementing Salesforce is setting up the sObjects to represent many-to-many relationships. A junction object allows a single instance of one sObject type to be related to multiple instances of another sObject type and vice versa.

This requires the user to create a new instance of the junction object and populate master-detail fields to associate two sObjects with each other, resulting in a large number of clicks and page transitions.

In this recipe, we will create a custom object– account group – that acts as a container for multiple accounts. We will then create a page that allows a number of accounts to be associated with a single custom sObject. We will use junction objects for the relationship to allow a single account to be related to multiple account groups, and a single account group to be associated with multiple accounts. A custom Visualforce component will manage the action of presenting the available accounts...
