Hi Bharat,

Greetings to you!

Try this: 
public integer countapprovedrecords=0;

for (myWrapper record : IncList){

 if(record.selected){

  countapprovedrecords++;
        }
}

if (!Apexpages.hasMessages()){
        string countstring = string.valueof(countapprovedrecords);
        system.debug('integer converted to string' +countstring);
        ApexPages.addMessage(new ApexPages.addMessage(new ApexPages.message(ApexPages.severity.Confirm, countstring+  'records selected!'));
                           
}

Also, please refer to the below links which might help you further with the above requirement.

Thanks for the reply....
I actually wanted to display live count 
eg. if a checkbox is checked it should display on the visual force page count = 1 and when deselected then it should display zero....

Hi Bharat,
Please do try this code below and you will surely be able to display live count of selected accounts on your vf page.

Vf page:
<apex:page controller="CountLiveController">
    <script>
        function test()
      {
          console.log('>>yes');
          methodOneInJavascript();
      }
        
        </script>
    <apex:form id="frm" >
        
        <apex:actionFunction action="{!methodOne}" name="methodOneInJavascript" rerender="frm"/>

           <apex:pageBlock title="Accounts">

            <apex:pageBlockTable value="{!wrapList}" var="a">
                <apex:column headerValue="Select Account">
                    <apex:inputCheckbox value="{!a.selected}" onchange="test();"/> 
                    
                </apex:column>
                <apex:column headervalue="Account Name" value="{!a.acc.name}"/>
            </apex:pageBlockTable>
             <apex:pageBlockSection>
          Live Count::: {!Count}
            </apex:pageBlockSection>
        </apex:pageBlock> 
    </apex:form>
</apex:page>

Controller class:
public class CountLiveController {
    public List<Account> acList{get;set;}
    public List<AccountWrapper> wrapList{get;set;} 
    public List<AccountWrapper> selectedWrap{get;set;}
    public Integer Count{get;set;}
    public CountLiveController()
    {
        acList=new List<Account>();
        selectedWrap = new List<AccountWrapper>();
        acList=[Select name from Account limit 10];// Show number of accounts as per requirement
        wrapList=new List<AccountWrapper>();
        for(Account a:acList)
        {
           AccountWrapper aw=new AccountWrapper(a);
           wrapList.add(aw); 
        }
        System.debug('>>wrapList'+wrapList);
    }

    public class AccountWrapper{
        public Boolean selected{get;set;}
        public Account acc{get;set;}
      public AccountWrapper(Account a)
      {
          acc=a;
          selected=false;
      }
    }
     
   public void methodOne()
   {
       selectedWrap.clear();
       for(AccountWrapper wrap:wrapList)
       {
          if(wrap.selected==true)
          {
             selectedWrap.add(wrap);
          }
          Count=selectedWrap.size(); 
         system.debug('::::'+selectedWrap);
       }  
   }
}

How would you modify this so instead of a count you had a sum / aggregation of a currency field on the account record?
e.g. live amount instead of live count.

Many thanks
