I have faced some requirement in my development work . User must be able to select all the record in the page block table in one click . So I added header check-box in page block table .
Here is the code how I achieved this. Only Java Script code I have used .
This is the my page
<apex:page controller="ControllerforheaderCheckboxinPBT">
<script type="text/javascript">
function checkAll(cb){
var inputElem = document.getElementsByTagName("input");
for(var i=0; i<inputElem.length; i++){
if(inputElem[i].id.indexOf("checkedone")!=-1)
inputElem[i].checked = cb.checked;
}
}
</script>
<apex:pageMessages />
<apex:form >
<apex:pageBlock Title="ALL CONTACTS" >
<apex:commandButton value="mass delete" action="{!massdelete}" id="massdelete" onclick="return confirmDelete()"/>
<apex:pageBlockTable value="{!Contacts}" width="100%" var="c" cellpadding="2" border="1" rowClasses="odd,even" styleClass="tableClass" id="opp_table">
<apex:column >
<apex:facet name="header">
<apex:inputCheckbox >
<apex:actionSupport event="onclick" action="{!GetSelected}" onsubmit="checkAll(this)" rerender="opp_table" status="newStatus"/>
</apex:inputCheckbox>
</apex:facet>
<apex:inputCheckbox value="{!c.selected}" id="checkedone">
<apex:actionSupport event="onclick" action="{!GetSelected}" rerender="opp_table"/>
</apex:inputCheckbox>
</apex:column>
<apex:column headervalue="AccountName" styleClass="showline">
<apex:outputField value="{!c.con.AccountId}" />
</apex:column>
</apex:pageBlockTable>
</apex:pageBlock>
</apex:form>
</apex:page>
My Controller..
public with sharing class ControllerforheaderCheckboxinPBT {
public Contact contact{get;set;}
public Id contactId{get;set;}
List<ContactWrapper> contactList = new List<ContactWrapper>();
List<Contact> selectedContacts = new List<Contact>();
public ControllerforheaderCheckboxinPBT() {
Contact contact = new Contact();
}
public List<ContactWrapper> getContacts() {
for(Contact c: [SELECT Id,Name,Accountid,loginURL__c,Account.Name,MobilePhone,Email FROM Contact ORDER BY createdDate DESC]){
contactList.add(new ContactWrapper(c));
}
return contactList;
}
public PageReference getSelected() {
System.debug('======Inside the Get Function======');
selectedContacts.clear();
//adding contacts in list
for(ContactWrapper conWrapper: contactList) {
if(conWrapper.selected == true) {
conWrapper.isChanged = true;
selectedContacts.add(conWrapper.con);
}
}
return null;
}
public PageReference massDelete() {
//deleting that list
if(selectedContacts.size()>0){
delete selectedContacts;
}
//showing an message to select one contact
else{
ApexPages.addMessage(new ApexPages.message(ApexPages.severity.ERROR,'Please select at least one Contact.'));
return null;
}
PageReference headerCheckboxPage = new PageReference('/apex/headerCheckboxinPBT');
headerCheckboxPage .setRedirect(true);
return headerCheckboxPage ;
}
public class ContactWrapper {
public Contact con{get; set;}
public Boolean selected{get; set;}
public ContactWrapper(Contact c) {
con = c;
selected = false;
}
}
}
