    <p>I was trying to figure out how to implement method_missing in C# 4, based on all of 2 blog posts floating around on IDynamicObject. </p> <p>What I want to do is have a Business Logic Layer that has a Repository, and if the method is missing from the Business Logic Layer, just call the Repository and pass through its result. So i have a class that looks like this:</p> <pre><code>public class CustomerServices : IDynamicObject { protected CustomerRepository _Repository = new CustomerRepository(); MetaObject IDynamicObject.GetMetaObject(Expression parameter) { return new RepositoryMetaObject&lt;CustomerRepository&gt;(_Repository, parameter); } } </code></pre> <p>In RepositoryMetaObect I implement the Call method like so:</p> <pre><code> public override MetaObject Call(CallAction action, MetaObject[] args) { typeof(T).GetMethod(action.Name).Invoke(_Repository, getParameterArray(args)); return this; } </code></pre> <p>(The rest of RepositoryMetaObject code probably isn't interesting, but I've included it here: <a href="http://pastie.org/312842" rel="nofollow noreferrer">http://pastie.org/312842</a>)</p> <p>The problem I think is that I'm never doing anything with the result of the Invoke, I'm just returning the MetaObject itself. </p> <p>Now when I do this:</p> <pre><code> dynamic service = new CustomerServices(); var myCustomer = service.GetByID(1); </code></pre> <p>GetByID is called, but if I try to access a property on myCustomer, is just hangs. </p> <p>Can anyone please help?</p> <p>Complete code can be downloaded ehre: <a href="https://dl.getdropbox.com/u/277640/BusinessLogicLayer.zip" rel="nofollow noreferrer">https://dl.getdropbox.com/u/277640/BusinessLogicLayer.zip</a></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.
