How to set RecordType in StandardController VisualForce when page load

Question

I am able to get record in controller and getting the recordtypeid that I wanted to assign the record

private ApexPages.StandardController ctrl;
public FTR__c ftrObj {get;set;}

public FTR_Controller(ApexPages.StandardController controller) {
    this.ctrl = controller;
    this.ftrObj = (FTR__c) controller.getRecord();

    this.ftrObj.RecordTypeId = Schema.SObjectType.FTR__c.getRecordTypeInfosByName().get('FTR OE Record Type').getRecordTypeId();
}

But how to set it to currentpage record??
Is there any workaround to set it to controller like: controller.setRecord(ftrObj) ?

What I want is when the VisualForce page load, the object is predefined to specific record type

There is one problem with this. You can not perform a DML in constructor, as per Salesforce standards, so you wont be able to update the record in the constructor.

If you need to retrieve the picklist values based on the record type of the user, you might wanna do this:

Visualforce page

<apex:page controller="Sample">
    <apex:form >
        <apex:inputField value="{!objEmp.Approval_Status__c}"/>
        <br/><br/><br/>
        <apex:inputField value="{!objEmp1.Approval_Status__c}"/>
    </apex:form>
</apex:page>

Controller

public with sharing class Sample { 

    public Employee__c objEmp {get;set;}
    public Employee__c objEmp1 {get;set;}

    public Sample() {
        objEmp1 = new Employee__c(RecordTypeId = '0120P000000EDfb');
        objEmp = new Employee__c(RecordTypeId = '0120P000000EDfg');
    }

}

This will result in the picklist values regarding record type.

If you still feel the need to update the record as according to your requirement, you may find this workaround useful: https://developer.salesforce.com/forums/?id=906F0000000AjPRIA0
