Visualforce Development Cookbook

Overview of this book

Visualforce, in conjunction with Apex, makes it easy to develop sophisticated, custom UIs for Force.com desktop and mobile apps without having to write thousands of lines of code and markup. The "Dynamic Binding" feature of Visualforce lets you develop generic Visualforce pages to display information related to the records without necessarily knowing which data fields to show. This is accomplished through a formula-like syntax, which makes it simple to manage even a complex hierarchy of records. "Visualforce Development Cookbook" provides solutions for 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 required help throughout. "Visualforce Development Cookbook" starts with explaining the simple utilities and builds up to advanced techniques for data visualization and reuse of functionality. This book contains recipes that cover various topics like 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. "Visualforce Development Cookbook" provides lots of practical examples to enhance and extend the Salesforce user interface.

Passing action methods to components


A controller action method is usually invoked from the Visualforce page that it is providing the logic for. However, there are times when it is useful to be able to execute a page controller action method directly from a custom component contained within the page. One example is for styling reasons, in order to locate the command button that executes the action method inside the markup generated by the component.

In this recipe we will create a custom component that provides contact edit functionality, including command buttons to save or cancel the edit, and a Visualforce page to contain the component and supply the action methods that are executed when the buttons are clicked.

How to do it…

This recipe does not require any Apex controllers, so we can start with the custom component.

  1. Navigate to the Visualforce Components setup page by clicking on Your Name | Setup | Develop | Components.

  2. Click on the New button.

  3. Enter ContactEdit in the Label field.
