If Event_Request__c is a custom object with field EventName__c (as per your note to @Martin.Kona) then to list all EventName__c you can't use a VF page on a single Event_Request__c as that will display only one event. Furthermore, the value= attribute on pageBlockTable has to take a list, not a single string

What you need is to use a standardSetController which you define on the VF page with a page attribute recordSetVar

<apex:page docType="html-5.0"  standardController="Event_Request__c" recordSetVar="EventRequests">

and then use {!EventRequests} as the value attribute in the pageBlockTable

<apex:pageBlockTable value="{!EventRequests}" var="con">

Now - all that said, standardSetControllers are a larger topic in and of themselves and it is worth reading VF in Practice, chapter 4 to learn about pagination, filters, and other bits. If you have issues, post a separate question once you get the basics working

  • Yes that was the problem, But after doing all this i am not getting all record in column. its returning only 21 record. it should be more that 100. any idea what should be done to get all record. – Salesfor_dev Feb 10 '16 at 20:33
  • yes - that is because by default, standardsetControllers return only 20 records; you need to read up on how to do pagination, filters, and possibly custom standardsetcontroller extensions. Do some research first and then post a new question if stuck – cropredy Feb 10 '16 at 20:39

You have to specify, what kind of relationship this Event_Request__c with EventName__c has. Typically, your code would look like this, if Event_Request__c had EventName__c as a childs.

<apex:pageBlock title="Contact details for account" >
  <apex:pageBlockTable value="{!Event_Request__c.EventName__c}" var="con">
     <apex:column value="{!con.Name}"/>
  </apex:pageBlockTable>
</apex:pageBlock>

Are you sure, that EventName__c isnt just a custom field? Please provide object model.

In the above code given by Martin, use Event_Request__c.EventName__r instead of Event_Request__c.EventName__c. This will fetch you the Name of the Contact provided you pass the recordId as paramter in the url of your page.

https://URL/apex/PageName?id=recordId

  • it was the recordSetVar problem. i declared recordSetVar and its working now. – Salesfor_dev Feb 10 '16 at 20:31
