    <p>I'm developing an asp.net (classic) application trying to implement the MVP pattern <a href="http://haacked.com/archive/2006/08/09/ASP.NETSupervisingControllerModelViewPresenterFromSchematicToUnitTestsToCode.aspx" rel="nofollow noreferrer">using this example</a>. In trying to unit test my presenter and using the following pattern, the psuedocode for which looks like so</p> <pre><code>//base view interface public interface IView { event EventHandler Init; event EventHandler Load; bool IsPostBack { get; } void DataBind(); bool IsValid { get;} } //presenter psuedo code public class SomePresenter { public SomePresenter(ISomeDomainService service, IView someView) { ... //HOW DO WE TEST/VERIFY THAT THIS REGISTRATION OCCURS? someView.Init += OnInit; someView.Load += OnLoad; } } ... //consuming code that exercises the above code, that needs to be tested var presenter = new SomePresenter(someDomainService, someView); </code></pre> <p>How do I verify that the presenter is doing what is expected i.e. registering for the Init and Load events? While this is easily done in the <a href="http://haacked.com/archive/2006/08/09/ASP.NETSupervisingControllerModelViewPresenterFromSchematicToUnitTestsToCode.aspx" rel="nofollow noreferrer">Phil Haack's example</a> using Rhino mocks...</p> <pre><code>[Test] public void VerifyAttachesToViewEvents() { viewMock.Load += null; LastCall.IgnoreArguments(); viewMock.PostSaved += null; LastCall.IgnoreArguments(); mocks.ReplayAll(); new PostEditController(viewMock, this.dataServiceMock); mocks.VerifyAll(); } </code></pre> <p>... how can we do this using MOQ?</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.
