Hello Everyone,

Below is my controller and VF page but for some reason it is not showing me the related contacts. Can you please advice?

Apex Class:

public with sharing class Second
{
public Account AC{ get; set; }  
public List<Contact> CI{ get; set; }

public second()
{
AC= new account();
CI = new list<Contact>();
}
public pagereference FindContacts()

{

    CI = [SELECT FirstName, LastName FROM Contact WHERE AccountId = :AC.parentid];

return null;
            
}
}

==================================================================================

VF:

<apex:page controller="Second">
<apex:form >

            <apex:pageBlock Title="Select Account">
                 <apex:inputField value="{!AC.parentid}"/>

<apex:commandButton action="{!FindContacts}" value="FindContacts" reRender="contacts"/>
                 
               </apex:pageblock>

<apex:pageblock id="Contacts" Title="Contacts" >
<apex:pageBlockTable value="{!CI}" var="AB" >

                         <apex:column value="{!AB.firstName}"/>
                        <apex:column value="{!AB.lastname}"/>
</apex:pageBlockTable>
</apex:pageBlock>
</apex:form>
</apex:page>

I am new to the VF and if somebody can explain the "Contacts" above in bold used in reRender and <apex:pageblock id="Contacts" Title="Contacts" > then it will really help me to focus on right direction.

waiting for the replies
