Hi All,

I have created custom fields Credit_Card_Name__c, Credit_Card_Number__c in Contact object. And i have created one custom object - Credit_Card__c with fields Name, Card_Holder_Email__c, Credit_Card_Number__c. 
I have created one custom button (name: Credit Card) on contact object of type (Display Type: Detail Page Button, Content Source: Visualforce Page).
I have inserted the records for Credit Card object.

When I click on custom button (name: Credit Card), I want to retrieve and display only those records which are related to Contact email in the form PageBlockTable with Radio buttons. After selecting one credit card, those details should be displayed in Contact object fields Credit_Card_Name__c, Credit_Card_Number__c.
I can achieve this by using below class. But i want to do the same using wrpapper class so that credit cards will be displayed in the form of pageBlockTable along with Radio buttons.
Thanks.

public Class ContactCreditDetailsPage
{
    private final Contact conObject = null;
    public String selectedCard{get; set;} //This is for updating selected credit card details in Contact object
    public List<Contact> con2 {get; set;} //This is for retrieving only those credit cards whose email is same as Contact record.
    public List<Credit_Card__c> ccard {get; set;}
    public List<Credit_Card__c> results; // For retrieving the credit cards from object - Credit_Card__c
