How to give "required field" before creating the new record through controller in visualforce

Hi All,

I am trying to create mandatory field through controller. But, I am not getting any output.
Bellow is my code. I want User_Name__C and Password__C as required fields.

VF Page :

<apex:page standardController="Registration__c" extensions="RegistrationExtention" >
<script>
function mySubmit(){
    var sub=confirm("Are you Sure, You want to submit the data");
    if(sub==true){
        return true;
    }
    else{
    return false;
    }

}


</script>
<style>

</style>

<apex:form id="frm" >
   
<apex:pageBlock id="pb">
<div  style="height:400px;">

<table bgcolor="#CEF6E3" align="center" style=" width:100%; height:400px; font-size:15px;  "   >

to make required field you can make use of required attribute. less code looks good. ;)

<apex:inputField value="{!reg.User_Name__c}" style="margin-left:-400px;" required="true"/>.

In your case i feel pr.setredirect(false); should work.

Hi sharathchandra thukkani,

Thanks for your reply,

Please check below post. I hope that will help you for Error Msg
1) http://www.sfdcpoint.com/salesforce/show-error-message-visualforce-page/
2) http://www.oyecode.com/2014/04/apex-messages-in-salesforce-show.html
3) http://www.infallibletechie.com/2012/10/how-to-display-error-messages-in.html

Ideally this is how you show error messages using Apex 
public PageReference processMessage(){
    //some code here
    if(somthingisTrue) {
       return null;
    } else {
      ApexPages.Message msg = new Apexpages.Message(ApexPages.Severity.Warning,'No Record Found' );
      ApexPages.addmessage(msg);
      return null; 
    } 
}
<apex:pageMessages id="showmsg"></apex:pageMessages>

In your it look liye you are not refreshing full page. Try to remove reRender and onclick method. I hope that will work

   <apex:commandButton style="margin-left:500px" value="Submit" action="{!dosave}"  /> 
public PageReference dosave(){
        Registration__c reg1=new Registration__c();
        
        reg1.Name=reg.Name;        
        reg1.First_Name__c=reg.First_Name__c;
        reg1.Gender__c=reg.Gender__c;
        reg1.Mail_Id__c=reg.Mail_Id__c;
        reg1.Phone__c=reg.Phone__c;
        reg1.Date_of_Birth__c=reg.Date_of_Birth__c;
        reg1.User_Name__c=reg.User_Name__c;
        reg1.Password__c=reg.Password__c;
        reg1.Confirm_Password__c=reg.Confirm_Password__c;    
        if(reg1.User_Name__c==null || reg1.User_Name__c==''){           
            reg.User_Name__c.addError('It is required Field');
            //ApexPages.addMessage(new ApexPages.Message(ApexPages.SEVERITY.FATAL, 'Name is required.'));
            return null;
        }else{
            insert reg1;
        
        PageReference pr=new PageReference ('/apex/loginpage');
        pr.setredirect(true);
        return pr;
        }
