Displaying Related Lists for Custom Objects

Displaying custom objects and their related lists with Visualforce is very simple.

Suppose you have three custom objects: MyChildObject, MyMasterObject, and MyLookupObject. MyChildObject has a master-detail relationship with MyMasterObject (which is the master). MyLookupObject also has a Lookup relationship with MyChildObject.

If you want to create a Visualforce page that displays the related list for MyMasterObject, use the following markup:

<apex:page standardController="MyMasterObject__c">
    <apex:relatedList list="MyChildObjects__r" />
</apex:page>
