asoyer Passing selected record ids to Apex controller from List View
I'm looking for an alternative to passing selected records from a List View via the URL. Here is how I'm currently doing it, but I'm running into IE URL limits when more than 100 records are selected. This is a custom List view button executing JavaScript.
var ids = {!GETRECORDIDS( $ObjectType.Account )};
if(ids.length < 1 ) {
alert('Please select at least one Account.')
}
else {
// window.open('/apex/Quick_Email?rec='+ids.join(',')+'&retURL=001/o');
window.location='/apex/Quick_Email?rec='+ids.join(',')+'&retURL=001/o';
}
What other methods could I implement?
You could create a custom list view button that points to a visual force page that uses the standard list controller and uses a custom controller extension to do the actions you want. For example:
VF Page:
<apex:page standardController="Account" recordSetVar="accounts" extensions="quickEmailController"> <apex:form > <apex:pageBlock > <apex:pageBlockTable value="{!selected}" var="account"> <apex:column value="{!account.name}"/> </apex:pageBlockTable> <apex:pageBlockButtons location="bottom"> <apex:commandButton value="Do Something" action="{!doSomething}"/> </apex:pageBlockButtons> </apex:pageBlock> </apex:form> </apex:page>Extension controller:
public class quickEmailController{ ApexPages.StandardSetController setCon; public quickEmailController(ApexPages.StandardSetController controller) { setCon = controller; } public pageReference doSomething() { // do something with the selected records for ( Account acc : (Account[])setCon.getSelected() ) { System.debug('Account name = ' + acc.Name); } return null; } }All Answers

public class quickEmailController{ ApexPages.StandardSetController setCon; public quickEmailController(ApexPages.StandardSetController controller) { setCon = controller; } public pageReference doSomething() { // do something with the selected records for ( Account acc : (Account[])setCon.getSelected() ) { System.debug('Account name = ' + acc.Name); } return null; } }Thanks tedward. this worked great. The StandardSetController did the trick.
Is it possible to use this technique without a Custom Button?
I would like to call a visualforce page like the one shown above with a set of records from another Visualforce Page with own Apex Controller:
public with sharing class myController { list<Account> Accounts;public PageReference CallOtherVisualforcePageWithListOfAccounts{ ApexPages.PageReference myRef = Page.MyPage; // Pass Accounts to myRef !?! } }
is there a way to accomplish that?
