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

Inline editing a record from a list


In the previous recipes, all records in a list have been editable. This works well when the user is expecting to edit a number of records but is not a great experience for users that predominantly view records. In this situation, it is better to give the user a read-only view of the records and a rapid way to edit a record if required.

In this recipe, we will create a Visualforce page that presents a list of contacts in read-only mode. The user may double-click on any field in order to edit the record details. Any changes to the contact records are stored locally until the user chooses to save or discard them.

Note

Standard Visualforce Markup provides support for inline editing, but this requires each field to be double-clicked to edit individually.

Getting ready

This recipe makes use of a custom controller that must be present before the Visualforce page can be created.
