Action support is not working for select all button--

Hi Friends,

           I have a requirement When I m selecting a single checkbox I m able to call a method in controller through actionSupport.
           when I am selecting a selectAll checkbox all checkboxes are selecting,
           but the actionsupport inside the checkbox is not calling the method,selctall functionality which I m aciving by javascript.

Any help would be greatly appreciated!!



Try the below code snippet as reference:





<apex:page controller="Checkbox_Class" Tabstyle="Account">


<apex:form >


<apex:pageBlock Title="Accounts with CheckBoxes">


<apex:pageBlockSection Title="List of Available Accounts">


<apex:dataTable value="{!accounts}" var="a" columnswidth="50px,50px" cellpadding="4" border="1">


<apex:column >


<apex:facet name="header"> <apex:inputCheckbox >


<apex:actionSupport event="onclick" action="{!GetSelected}" onsubmit="checkAll(this)" rerender="Selected_PBS"/>




<apex:inputCheckbox value="{!a.selected}" id="checkedone">


<apex:actionSupport event="onclick" action="{!GetSelected}" rerender="Selected_PBS"/>




<apex:column headervalue="Account Name" value="{!a.acc.Name}" />


<apex:column headervalue="Account Number" value="{!a.acc.AccountNumber}" />


<apex:column headervalue="Phone" value="{!a.acc.Phone}" />






<apex:pageBlockSection Title="Selected Accounts" id="Selected_PBS">


<apex:dataTable value="{!SelectedAccounts}" var="s" columnswidth="50px,50px" cellpadding="4" border="1">


<apex:column headervalue="Account Name" value="{!s.Name}" />


<apex:column headervalue="Account Number" value="{!s.AccountNumber}" />


<apex:column headervalue="Phone" value="{!s.Phone}" />












function checkAll(cb)




var inputElem = document.getElementsByTagName("input");


for(var i=0; i<inputElem.length; i++)






inputElem[i].checked = cb.checked;














public class Checkbox_Class



    List<accountwrapper> accountList = new List<accountwrapper>();


    List<Account> selectedAccounts = new List<Account>();



    public List<accountwrapper> getAccounts()




        for(Account a : [select Id, Name, AccountNumber, Phone from Account limit 5])


        accountList.add(new accountwrapper(a));


        return accountList;





    public PageReference getSelected()






        for(accountwrapper accwrapper : accountList)


        if(accwrapper.selected == true)




        return null;





    public List<Account> GetSelectedAccounts()






        return selectedAccounts;




        return null;





    public class accountwrapper




        public Account acc{get; set;}


        public Boolean selected {get; set;}


        public accountwrapper(Account a)




            acc = a;


            selected = false;
