control which fields are rendered in an output panel

I have approximately 20 fields in an output panel and I only want to display fields that have a value and hide the ones that do not.

 

I'm using a render tag for each field-rendered="{!IF(NOT(ISNULL(Contract__c.Status)),true,false)}"

 

Instead of using a render tag for each field, is there a way of inserting a tag in the output panel to do this? If so, how?

Hi Spunki

 

   Please make Custom Object named Book and Field Title ,Author , ...etc

   Now refer my code....

       <apex:page controller="Renderfieldcontroller">
  <apex:form>
    <apex:pageBlock>
       <apex:pageBlockSection columns="2" title="Book Information" rendered="{!Enable!='show'}">
       
       
          <apex:repeat value="{!threeFieldList}" var="afield" >
              <apex:inputField value="{!Book[afield]}"  />
          </apex:repeat><br/>
          
          <apex:commandButton value="Save" action="{!savingBook}"/>
      
       </apex:pageBlockSection>
       
       <apex:pageBlockSection columns="2" title="Book Information" rendered="{!Enable=='show'}">
      
          <apex:repeat value="{!threeFieldList}" var="afield" >
              <apex:outputField value="{!Book[afield]}" rendered="{!IF(NOT(ISNULL(Book[afield])),true,false)}"  />
          </apex:repeat><br/>
         
       </apex:pageBlockSection>
       
    </apex:pageBlock>
    </apex:form>
    </apex:page>

 

My controller is......

     public class Renderfieldcontroller {
   List<string>threeFieldList{get; set;}
   public final Book__c bok{get;set;}
   public String Enable{get;set;}
   public Renderfieldcontroller () {
      bok = new Book__c ();
      if (threeFieldList == null) {
                 threeFieldList = new List<String>();
                  threeFieldList.add('Author__c');
                 threeFieldList.add('Price__c');
                 threeFieldList.add('Publisher__c');
                  threeFieldList.add('Title__c');
                
                 }
      }
      
      public List<String> getthreeFieldList()
      {
        return threeFieldList;
        }
         
         public Book__c getBook() {
      
            return bok;
          }
          
         public PageReference savingBook() {
            upsert bok;
            Enable = 'show';
            return null;
      }
  }
