Body
I'm trying to create a dynamic object that can be used as a component of a static object. Here is a contrived example of what I'm trying to accomplish. Here is the dynamic component: <pre><code>public class DynamicComponent : DynamicObject { public override bool TryInvokeMember( InvokeMemberBinder binder, object[] args, out object result) { result = "hello"; return true; } } </code></pre> And here is a class where inheriting from <code>DynamicObject</code> isn't an option...assume that there is some third party class that I'm forced to inherit from. <pre><code>public class AStaticComponent : VendorLibraryClass, IDynamicMetaObjectProvider { IDynamicMetaObjectProvider component = new DynamicComponent(); public DynamicMetaObject GetMetaObject(Expression parameter) { var result = component.GetMetaObject(parameter); return result; } } </code></pre> The direct usage of <code>DynamicComponent</code> works: <pre><code>dynamic dynamicComponent = new DynamicComponent(); Assert.AreEqual(dynamicComponent.AMethod(), "hello"); </code></pre> However, forwarding the <code>GetMetaObject</code> through <code>AStaticComponent</code> causes some form of an infinite loop. <pre><code>dynamic dynamicComponent = new AStaticComponent(); Assert.AreEqual(dynamicComponent.AMethod(), "hello"); //causes an infinite loop </code></pre> Anyone know why this occurs? And if it's some baked in behavior of <code>DynamicObject</code> that I cannot change, could someone provide some help on how to create a <code>IDynamicMetaObjectProvider</code> from scratch to accomplish a component based dynamic object (just something to get things started)?

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.
