Fetching values between objects

Hi, 
    I have two objects 'A' & 'B' and a VF page. A field from object 'A' is a lookup in object 'B'. On selecting a lookup field of 'A', the values corresponding to that field have to be auto populated in my VF page. But it was not happening. 
Can anyone please explain why?

Note: VF page is of object 'B'. Iam using Lightning Experience.

Thanks in advance.

Please share your code as well so we can see where the problem is. Thanks.

If you have a visualforce page for object B, with a lookup field to object A, you can just use the relationship name to render the fields from it.. as simple as this:
  
<apex:page standardController="B__c">

    <apex:outputField value="{!B__c.Id}" />

    <apex:outputField value="{!B__c.A_lookup__r.Id}" />

</apex:page>

(so this renders the Id of object B first, and then the ID of object A, as it is found through the relationship field A_lookup__c on object B)

If something like this doesn't work then you have apparantly made something more complicated, but without the code/examples it is impossible to deduce! Hope this helps.
