Dynamically requiring a field in a field set

I am employing field sets to display intormation on a VF page. A new requirement is to dynamically require a field within the field set, based on information from a record in an associated object.

For example, if Object1.checkbox1 = true, then the field Object2.DogName is required on the page. 

In the context of using a field set, is there a way to dynamically require Object2.DogName to be either required or not based on the value of Object1.checkbox? 

Any help is greatly appreciated!

Hi Chuck, 


See the sample code in the blog below,

Hi,
I would suggest you the following

Create 2 field sets one with that specific field as required and another field set as not required. Then render that part of the page using conditions

For Example:

   <apex:pageblocksection rendered="{!Object1.checkbox1 = true}">  
      <apex:repeat value="{!$ObjectType.Account.FieldSets[$Setup.AccountFieldSetSettings__c.FieldSet1]}" var="f">
           <apex:outputText value="{!Account[f]}" /><br/>
     </apex:repeat>

  <apex:pageblocksection rendered="{!Object1.checkbox1 = false}">
      <apex:repeat value="{!$ObjectType.Account.FieldSets[$Setup.AccountFieldSetSettings__c.FieldSet2]}" var="f">
           <apex:outputText value="{!Account[f]}" /><br/>
     </apex:repeat>


Cheers..!!!

Hello,

My approach is below.

class: 
global static boolean classvarflag {get;set;}
//make the classvarflag true/false based on obj1.checked field -- The assginment can be done in constructor or action function
based on the flagvalue the specific field is mandatory.
if(obj1.checked) classvarflag=true;

<apex:pageBlockSection id="obj2pgs" rendered="{!IF($ObjectType.Account.FieldSets.Obj2fsname}">0} >
            <apex:repeat value="{!$ObjectType.Account.FieldSets.Obj2fsname}" var="f" id="rep">
                 <apex:inputField required="{!classvarflag}"  value="{!supplier[f]}" rendered="{!IF(CONTAINS(Lower(f), 'obj2.fieldname') , true , false)}"/>
                  <apex:inputField   value="{!supplier[f]}" rendered="{!IF(CONTAINS(Lower(f), 'obj2.fieldname') , false, true)}"/>
            </apex:repeat>
</apex:pageBlocksection>


Thanks,
