How to add/bind checkbox value in wrapper class

Hi everyone,

Recentetly I've added a form page where user can add much as rows as he wants. All of the input fields keep the previous row data in the form except the checkbox.

FYI, the checkbox does not belong to any standard or custom object, it is just a checkpoint for checking if certain input field checked or not.

I tried to declare the checkbox as List<Boolean> but same issue. Please advise.

Thanks

Abu, Are facing below issue?

When you clicks on "Add Row", it's not binding the existing selected one. Correct? 

I have ran your code in my dev org and its working as expected apart from above issue. 

If this is only an issue, Please remove "Immediate = true" attribute from "Add Row" button, it will not allow your data to bind your controller

Hi Abu,

Please post your current code here and will provide the solution on top of it.

You just need to use the public Boolean isSelected {get; set;} in the wrapper class.

Hi Abu,

Please see below code for example

Visualfore Page:
  
<apex:page controller="AccountController">
    <apex:form>
        <apex:pageBlock>
            <apex:pageBlockTable value="{!lstWrapper}" var="lstWrap">
                
                <apex:column>
                    <apex:inputCheckbox value="{!lstWrap.isSelected}" />
                    <apex:inputField value="{!lstWrap.objAccount.Name}" />
                </apex:column>
                
            </apex:pageBlockTable>
            
        </apex:pageBlock>
    </apex:form>
</apex:page>

Controller:
  
public with sharing class AccountController {
    
    public List<wrapperAccount> lstWrapper {get;set;}
    public AccountController()
    {
        lstWrapper = new List<wrapperAccount>();
        for(Account objAccount : [Select Id, Name from Account limit 10])
        {
            lstWrapper.add(new wrapperAccount(objAccount));
        }
    }
    
    public class wrapperAccount
    {
        public Boolean isSelected {get;set;}
        public Account objAccount {get;set;}
        
        public wrapperAccount(Account objAcc)
        {
            objAccount = new Account();
            isSelected = false;
            objAccount = objAcc;
        }
    }
}

Hi Prem,

Thank you, my scenerio is slightly different, I'm using your example and rearrange them according my situation


 

<apex:page controller="AddEmployeeIntakeController">
    <apex:form>
        <apex:pageBlock>
            <apex:pageBlockTable value="{!waContList}" var="eachRecord">
                
                <apex:column>
                    <apex:inputCheckbox value="{!eachRecord.createDisclosure}" />
                    <apex:inputCheckbox value="{!eachRecord.createPhoto}" />
                    <apex:inputCheckbox value="{!eachRecord.printsTaken}" />
                </apex:column>
                
            </apex:pageBlockTable>
            <apex:pageBlockButtons location="bottom" >
                <apex:commandButton value="Add Row" action="{!addNewRowToEmpList}"  rerender="accountHead" Status="status" immediate="true" />
            </apex:pageBlockButtons>              
        </apex:pageBlock>
    </apex:form>
</apex:page>
  
public with sharing class AddEmployeeIntakeController{
    
    public  List<WrapperContactList>     waContList       {get;set;}

    public AddEmployeeIntakeController()
    {
        waContList = new List<WrapperContactList>();
        addNewRowToEmpList();
    }
    
    public class WrapperContactList
    {
        public Boolean         createPhoto            {get;set;}
        public Boolean         printsTaken            {get;set;}
        public Boolean         createDisclosure       {get;set;}
    }

    public void addNewRowToEmpList(){
        WrapperContactList newRecord = new WrapperContactList();
        newRecord.createDisclosure  = false;
        newRecord.createPhoto       = false;
        newRecord.printsTaken       = false;
        waContList.add(newRecord);
    }
}
The problem is happening when trying to add a new row, then found that the previous checkboxes are uncheked. Which is because the the value of these fields are not binded in the wrapper.
