StandardController Class

Use a StandardController when defining an extension for a standard controller.

Namespace

ApexPages

Usage

StandardController objects reference the pre-built Visualforce controllers provided by salesforce.com. The only time it is necessary to refer to a StandardController object is when defining an extension for a standard controller. StandardController is the data type of the single argument in the extension class constructor.

Instantiation

You can instantiate a StandardController in the following way:
1swfobject.registerObject("clippy.codeblock-0", "9");ApexPages.StandardController sc = new ApexPages.StandardController(sObject);

Example

The following example shows how a StandardController object can be used in the constructor for a standard controller extension:

1swfobject.registerObject("clippy.codeblock-1", "9");public class myControllerExtension {
2
3    private final Account acct;
4    
5    // The extension constructor initializes the private member
6    // variable acct by using the getRecord method from the standard
7    // controller.
8    public myControllerExtension(ApexPages.StandardController stdController) {
9        this.acct = (Account)stdController.getRecord();
10    }
11
12    public String getGreeting() {
13        return 'Hello ' + acct.name + ' (' + acct.id + ')';
14    }
15}

The following Visualforce markup shows how the controller extension from above can be used in a page: 

1swfobject.registerObject("clippy.codeblock-2", "9");<apex:page standardController="Account" extensions="myControllerExtension">
2    {!greeting} <p/>
3    <apex:form>
4        <apex:inputField value="{!account.name}"/> <p/>
5        <apex:commandButton value="Save" action="{!save}"/>
6    </apex:form>
7</apex:page>
