    <p>I am working on a class library using C#. I have designed 3 main classes to help model our data. They are designed such that class A contains a list of class B instances, and class B contains a reference to a class C instance, ie: </p> <pre><code>public class Policy { public List &lt; PolicyTerm &gt; myTerms; person Customer; string PolicyNumber; } public class PolicyTerm { public Billing myBill; Datetime effectivedate; List &lt; Activities &gt; termActivities; public doAction() { use value from Policy, like PolicyNumber; } } public class Billing { float remainingBalance; Datetime nextDueDate; public void doSomething() { reference value from PolicyTerm, such as effective date; use value from Policy, such as PolicyNumber; } } </code></pre> <p>The problem I have is when I try to use a method within PolicyTerm or Billing that needs data from the containing class. In the example above, this would be the method "doSomething" trying to use a value from PolicyTerm, like the effective date for the term in requesting or saving data to our database.</p> <p>I am wondering if I have the correct design for my classes because of this scenario. Should I just add a reference to the "parent" class within the child classes, in order to make the parent's data available? Or do I need to rethink the overall structure and design of the code? </p> <p>I feel like the class design works well for modeling the data and our business rules, but it does create a few limitations like the above situation. I liked the separation of the PolicyTerm and Billing for the ability to allow that code to be modified and tested independently. Also, I feel like it keeps each section smaller and simpler.</p> <p>Any advice that can be provided would be much appreciated. </p> <p>Update: Code block was updated to provide more details on the code in question. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
