User-added image

I want when i hit save it should show error like above on the fields that are required on the page layout. Here is the VF page:
  
<apex:page standardController="Opp" extensions="oppsController">
    <apex:sectionHeader title="Opp Edit" subtitle="{!Opp.OppNumber}"/>
    <apex:form id="frmId">
   

        <apex:pageBlock id="pb" title="Opp Edit" mode="edit">
  <apex:messages ></apex:messages>
            <apex:pageBlockButtons >
            <apex:commandButton value="Save" action="{!save}" rerender="theForm"/>
 
            <apex:commandButton value="Cancel" action="{!Cancel}" rerender="theForm"/>
 
         </apex:pageBlockButtons> 


            <apex:pageBlockSection id="pb1" title="Opp" columns="2">
                <apex:inputField value="{!Opportunity.Account_name__c}" required="True"/>
                <apex:inputField value="{!Opportunity.Active_Status__c}" required="True"/>
                <apex:inputField value="{!Opportunity.OppNumber}" required="True"/>
                 <apex:inputField value="{!Opportunity.RecordTypeId}" required="True"/>
                
            </apex:pageBlockSection>


            <apex:pageBlockSection id="pb2" title="Details" columns="2">
              <apex:messages ></apex:messages>
                <apex:inputField value="{!Opportunity.Opp_Country__c}" required="true"/>
                <apex:inputField value="{!Opportunity.Region__c}" required="True"/>
                <apex:inputField value="{!Opportunity.Sub_Region__c}" required="True"/>
            </apex:pageBlockSection>
         
        </apex:pageBlock>
    </apex:form>
</apex:page>

Does anyone know how to fix it?

Thanks.

Thanks it worked :)
But what about validation error message. when i hit save error comes in this form 
Insert failed. First exception on row 0; first error: FIELD_CUSTOM_VALIDATION_EXCEPTION

Use apex:pagemessages instead of apex:messages

1. Add the <apex:pageMessages/> tag to your page. (This is the container that displays any error messages if present)

2. Surround your DML call with try {} catch(DMLException e) {} (When you catch the exception you won't get redirected to the error pages, but salesforce will automatically create a "PageMessage" for the validation failure.

Thanks I will try this out.

@Deepak: could you please explain why rerender="theForm" was not working? Why have to remove that in order to make it work?

There was no Id in VF page named "theForm"
R Z KhanR Z Khan
replace it with rerender="frmId"
