How to make Field as Required in Visualforce page?

Hi,

In this post i am giving a simple visualforce example of making a not-required field as required in Visualforce Page.

Visualforce Page:

<apex:page standardController="Account">

<apex:form >

 <apex:pageBlock >

   <apex:pageblocksection title="Account Information">

    <apex:inputfield value="{!account.Name}"/>

    <!--

    <apex:inputField value="{!account.AccountNumber}"/>    

       <apex:inputfield value="{!account.AccountNumber}" required="true"/>

    

   </apex:pageblockSection>

 <apex:pageblockButtons >

  

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

  </apex:pageblockButtons>

</apex:pageBlock>

</apex:form>  

</apex:page>

Output :

if you observe in the standard page layout the account-number is not required field on account object. i maed it as required in visualforce page with the 

 <apex:inputfield value="{!account.AccountNumber}" required="true"/> tag.

in Visualforce page if you try to save the record with out enter any value in Account Number field it is showing the error message 

That's it ...

Thanks for reading........
