    <p>You can replace the default <em>IModuleInitializer</em> for an instance of a custom class that instead of initializing the modules right after they are loaded, stores them in a modules list. When all modules have been loaded, you initialize them in whatever order you want.</p> <p>How to achieve this:</p> <p>1) In the bootstrapper, override the <em>ConfigureContainer</em> method to replace the default <em>IModuleInitializer</em> for a instance of the <em>MyModuleInitializer</em> class, yet maintaining the default initializer with a name (for example, <em>defaultModuleInitializer</em>):</p> <pre><code> protected override void ConfigureContainer() { base.ConfigureContainer(); var defaultContainer = Container.Resolve&lt;IModuleInitializer>(); Container.RegisterInstance&lt;IModuleInitializer>("defaultModuleInitializer", defaultContainer); Container.RegisterType&lt;IModuleInitializer, MyModuleInitializer>(new ContainerControlledLifetimeManager()); } </code></pre> <p><br/> 2) Create the <em>MyModuleInitializer</em> class that performs the desired storea-all-then-sort-and-initialize procedure:</p> <pre><code> public class MyModuleInitializer : IModuleInitializer { bool initialModuleLoadCompleted = false; IModuleInitializer defaultInitializer = null; List&lt;ModuleInfo> modules = new List&lt;ModuleInfo>(); public MyModuleInitializer(IUnityContainer container) { defaultInitializer = container.Resolve&lt;IModuleInitializer>("defaultModuleInitializer"); } public void Initialize(ModuleInfo moduleInfo) { if(initialModuleLoadCompleted) { //Module loaded on demand after application startup - use the default initializer defaultInitializer.Initialize(moduleInfo); return; } modules.Add(moduleInfo); if(AllModulesLoaded()) { SortModules(); foreach(var module in modules) { defaultInitializer.Initialize(module); } modules = null; initialModuleLoadCompleted = true; } } private bool AllModulesLoaded() { //Here you check whether all the startup modules have been loaded //(perhaps by looking at the module catalog) and return true if so } private void SortModules() { //Here you sort the "modules" list however you want } } </code></pre> <p>Note that after all the startup modules have been loaded, this class reverts to simply invoking the default initializer. Adapt the class appropriately if this is not what you need.</p>

    1. COThis is a pretty good solution. The only tricky part is knowing when "AllModulesLoaded". Since i'm using the DirectoryModuleCatalog, i don't really have an easy way of knowing that. Thanks for the answer; i've solved the problem a completely different way.

    2. CO+1 I like this one more than the accepted answer: there I don't like the idea that modules have to know about the order in which they're loaded, let alone about the names of those modules.

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.
