Visualforce page that shows Contact details using an Extension controller

Create a Visualforce page that shows Contact details using an Extension controller

Extension Controller: use to build custom functionalities that are not available at Standard controller. We can create more than one extension controller at a visualforce page.

Visualforce Page:

<apex:page standardController="Contact" extensions="contactExtension">

<apex:form>



<apex:inputField value="{!contact.FirstName}"/> <p/>

<apex:inputField value="{!contact.LastName}"/> <p/>

<apex:commandButton value="Save" action="{!save}"/>

    </apex:form>

</apex:page>

Extension Controller:

public class contactExtension {


private final Contact cons;


// The extension constructor initializes the private member












public contactExtension (ApexPages.StandardController stdController) {



this.cons = (Contact)stdController.getRecord();

}

return 'Hello Mr./Ms. ' + cons.LastName + ' (' + cons.id + ')';



}
