A custom list controller is similar to a standard list controller. Custom list controllers can implement Apex logic that you define to show or act on a set of records.
public class opportunityList2Con { // ApexPages.StandardSetController must be instantiated // for standard list controllers public ApexPages.StandardSetController setCon { get { if(setCon == null) { setCon = new ApexPages.StandardSetController(Database.getQueryLocator( [SELECT Name, CloseDate FROM Opportunity])); } return setCon; } set; } // Initialize setCon and return a list of records public List<Opportunity> getOpportunities() { return (List<Opportunity>) setCon.getRecords(); } }
public with sharing class AccountPagination { private final Account acct; // The constructor passes in the standard controller defined // in the markup below public AccountPagination(ApexPages.StandardSetController controller) { this.acct = (Account)controller.getRecord(); } public ApexPages.StandardSetController accountRecords { get { if(accountRecords == null) { accountRecords = new ApexPages.StandardSetController( Database.getQueryLocator([SELECT Name FROM Account WHERE Id NOT IN (SELECT AccountId FROM Opportunity WHERE IsClosed = true)])); } return accountRecords; } private set; } public List<Account> getAccountPagination() { return (List<Account>) accountRecords.getRecords(); } }
<apex:page standardController="Account" recordSetVar="accounts" extensions="AccountPagination"> <apex:pageBlock title="Viewing Accounts"> <apex:form id="theForm"> <apex:pageBlockSection > <apex:dataList value="{!accountPagination}" var="acct" type="1"> {!acct.name} </apex:dataList> </apex:pageBlockSection> <apex:panelGrid columns="2"> <apex:commandLink action="{!previous}">Previous</apex:commandlink> <apex:commandLink action="{!next}">Next</apex:commandlink> </apex:panelGrid> </apex:form> </apex:pageBlock> </apex:page>
