setSelected(selectedRecords)
Signature
public Void setSelected(sObject[] selectedRecords)
Parameters
- selectedRecords: Type: sObject[]
Return Value
Type: Void
Usage
Use the setSelected() method in your Apex controller or controller extension to manually set the records displayed on a Visualforce page. The setSelected() method overwrites any previously selected records with the records specified in the selectedRecords argument.
Example
AccountNamePage shows a table of account names. MyControllerExtension’s constructor contains a SOQL query that returns a list of accounts. This list is passed into setSelected() so that the account records in the list are selected and displayed in the table.
1<!-- AccountNamePage.page -->
2<apex:page standardController="Account" recordSetVar="accounts" extensions="MyControllerExtension">
3 <apex:pageBlock>
4 <apex:pageBlockTable value="{!accounts}" var="acc">
5 <apex:column value="{!acc.name}"/>
6 </apex:pageBlockTable>
7 </apex:pageBlock>
8</apex:page>
