Hi,

 

Since you are trying to display the related list, you have to use that in a datatable or pageblocktable

for iteration i think

 

Try to use the same in datatable

 

 

<apex:datatable value="{!Event__c.Registrant__r}" var="evereg">
<apex:column value="{!evereg.Name}"/>
give all the fields as above
</apex:datatable>

 Thanks

Arvind

I am still getting the error

 

 

Error: Invalid field Registrant__r for SObject Event__c

Can you please check the Registrant object name once.

Because I am able to save the code which I posted without any error. But when I give some other name for

the child object, I am getting the same error as you are getting

 

My object names are : A, B

 

I am using the following code:

<apex:page standardController="A__c">
  <apex:form>
      <apex:dataTable value="{!A__c.B__r}" var="t">
      <apex:column>
      <apex:inputField value="{!t.name}"/>
      </apex:column>
      </apex:dataTable>
  </apex:form>
</apex:page>

 

Here A is parent and B is child

If you have two objects Event__C and Registrant__C and Registrant__c is the child, you need to use pulural object for the related one. Try using this way.

 

Event__c.Registrants__r
