Standard Controllers
Standard controllers are a fundamental feature of Salesforce Visual Pages that facilitate seamless interaction between data and user interfaces. These controllers provide a bridge between the front-end user experience and the back-end data, allowing developers to create dynamic and data-driven pages with ease. In this article, we will delve into the concept of standard controllers, their importance, a step-by-step example, and conclude with sample questions to reinforce understanding.

Understanding Standard Controllers:
A standard controller is a pre-built class provided by Salesforce that connects Visual Pages with standard or custom objects in the database. These controllers offer a set of methods and properties that enable developers to retrieve, modify, and save data, as well as navigate through records. Standard controllers handle much of the underlying data manipulation and interaction logic, freeing developers from having to write extensive code for basic operations.
Benefits of Standard Controllers:
1. Rapid Development: Standard controllers streamline the development process by
providing out-of-the-box functionality for data retrieval and manipulation, reducing
the need for custom coding.
2. Consistency: By leveraging standard controllers, developers adhere to consistent
Salesforce best practices, ensuring a standardized user experience.
3. Data Security: Standard controllers respect the data access permissions defined
in Salesforce, ensuring that users only see and manipulate data they are authorized
to access.
4. Seamless Integration: Standard controllers seamlessly integrate with other
Salesforce features, such as validation rules, workflows, and triggers.
Example: Creating a Contact Details Page
Let's illustrate the use of standard controllers with an example of a Visual Page that displays and edits contact details. We'll use the standard Contact object and its associated standard controller to create a dynamic Contact Details Page.
Step 1: Create a Visual Page
● Access the Lightning App Builder.
● Create a new Lightning Page and select the "Record Page" type.
● Choose the "Contact" object as the source.
Step 2: Add Components
● Drag and drop components onto the page canvas, such as a detail section for contact
information and an edit section for data modification.
● Associate the components with the standard controller of the Contact object.
Step 3: Leverage Standard Controller Methods
● Utilize standard controller methods like "getRecord" to retrieve the contact
details and populate the detail section.
● Use "saveRecord" to update and save modifications made by the user in the edit
section.
With standard controllers, developers can quickly build a Contact Details Page that allows users to view and edit contact information seamlessly.
In conclusion, standard controllers in Salesforce Visual Pages empower developers to create dynamic and data-driven interfaces with minimal coding effort. By understanding their capabilities and applying them to real-world scenarios like the Contact Details Page, developers can harness the power of standard controllers to build user-friendly and efficient Visual Pages that seamlessly interact with Salesforce data.
