display all fields of most recent related list record on parent object?

I have three custom objects (A, B, C with A being the parent of B; B being the parent of C).

Goal: Create a single console screen with :
  • all details for Object A
  • all details for the most recent Object B
  • all records for Object C that are related to the most recent Object B
     
1. Is this possible?
2. Can anyone give me a high-level starting point so I can start researching from there

I've tried lots of things with creating different Visualforce pages to display different details from the various Objects, but i just can't get it to work.

Create a page that uses the standard controller for "A".  Create a controller extension that gets the "A" record from the standard controller, and queries for the most recent "B" record.  Something like this:

B bRecord = [SELECT Id, other fields FROM B ORDER BY CreatedDate DESC LIMIT 1];

Then you can get all the "C" records related to the "B" record:

List<C> cRecords = [SELECT Id, other fields FROM C WHERE B_Lookup__c = :bRecord.Id];

In the VF page, display the details for the "A" and "B" records, then use a "pageBlockTable" (or maybe a "repeat") to show all the "C" records:

<apex:pageBlockTable value="{!cRecords}" var="crecord" >
    <apex:outputField value="{!crecord.A_Field__c}"/>
    and so on...
</apex:pageBlockTable>

I hope this helps.  Let me know if you have any more questions.

Thanks, Glyn! Using your advice and some code I found in a blog post, I successfully created the controller to get B record like this:

public class risk_Controller
    {
        public String  propNPI{ get; set; }
        public String  propAttProvider{ get; set; }
        public Double  propPriorityLevel{ get; set; }
        public Double  propFinancialValue{ get; set; }
        public Double  propRiskScore{ get; set; }
       

    public risk_Controller()
        {
              Risk_Profile__c obj = [SELECT   id,
                                              Attributed_NPI__c,
                                              Attributed_Provider__c,
                                              Total_Member_Priority_Level__c,
                                              Total_Potential_Financial_Value__c,
                                              Total_Potential_Risk_Score__c 
                                     FROM Risk_Profile__c limit 1];
              propNPI = obj.Attributed_NPI__c;
              propAttProvider = obj.Attributed_Provider__c;
              propPriorityLevel = obj.Total_Member_Priority_Level__c;
              propFinancialValue = obj.Total_Potential_Financial_Value__c;
              propRiskScore = obj.Total_Potential_Risk_Score__c;
                
             

        }
     }

Now I need to get the C records. I'm a newbie to apex coding, so I'm not sure how to put the records into the list variable. Can you possibly provide any guidance on the code for your psuedocode related to Object C?

List<C> cRecords = [SELECT Id, other fields FROM C WHERE B_Lookup__c = :bRecord.Id];

Thank you for any help you can provide - much appreciated!

One possible problem with your code is that, while it gets a Risk_Profile__c record, it's an arbitrary one - not necessarily the one associated with your "Object A" record.

The code in the following post is an alternative.  I've included some VF code as well to see how the controller extension is used.  Let me know if you have any questions or find any typos.

Thank you so much for your help. Right now, I'm getting the following error (FYI ACA_Member__c is the name of Object A):

SObject row was retrieved via SOQL without querying the requested field: ACA_Member__c.Name__c

I'll post the code as I edited it (with my custom object names). Maybe I've made a typo somewhere? Again, thank you so much for any help you can provide.

Also, FYI, when I remove the line of code <apex:outputField value="{!aRecord.Name}"/> from the VF page, it works beautifully! I just have to do some formatting and bring in more fields (I was using minimal fields just to test) and it'll be perfect. 

I can't thank you enough! If the last little piece can be figured out, it'll be totally perfect! Thank you, Glyn!

In the VF code, replace:

<apex:outputField value="{!aRecord.Name}"/>

with:

<apex:outputField value="{!ACA_Member__c.Name}"/>

This will use the standard controller's version of the record, and will let the standard controller know that you need the Name field.  Any fields you specify this way will be queried for you by the standard conttoller.
