The generic Dictionary collection class in .NET requires the key to be unique. But many applications/services require a flexible, generic Dictionary collection type that can accept multiple values for a key. This article explains one such generic Dictionary collection type.

ASP.NET MVC enables Web developers to build compelling standards-based Web solutions that are easy to maintain because it decreases the dependency between layers by using the Model-View-Controller (MVC) pattern and provides complete control over the page markup. It also improves testability which enables Test Driven Development (TDD). Click here to download ASP.NET MVC or to learn more about it.

Call Handlers are Enterprise Library's extension mechanism. They allow code to be injected before or after a method is called. Enterprise Library, as of version 4.1, comes with the following call handlers and associated handler attributes, in assembly Microsoft.Practices.EnterpriseLibrary.PolicyInjection.CallHandlers:

• AuthorizationCallHandler / AuthorizationCallHandlerAttribute
• CachingCallHandler / CachingCallHandlerAttribute
• ExceptionCallHandler / ExceptionCallHandlerAttribute
• LogCallHandler / LogCallHandlerAttribute
• PerformanceCounterCallHandler / PerformanceCounterCallHandlerAttribute
• ValidationCallHandler / ValidationCallHandlerAttribute

If you know the Enterprise Library, you can easily guess their meaning from their names.

I have written two additional call handlers:

• TransactionCallHandlerAttribute (implements ICallHandler): wraps the target method in a transaction scope
• TriesCallHandlerAttribute (implements ICallHandler): tries to invoke the target method a number of times, while an exception is thrown

For simplicity's sake, I have implemented ICallHandler in the attribute class, so the ICallHandler.CreateHandler method only returns this.

Usage is like this:

[TransactionCallHandler(TransactionScopeOption.Required)]

void SomeMethod();

and

[TriesCallHandler(3, Delay = 500)]

void SomeOtherMethod();

Enjoy!

When using  master pages, the normal page event lifecycle is a little different. Here is the actual order:

1. Page.OnPreInit
2. MasterPageControl.OnInit (for each control on the master page)
3. Control.OnInit (for each contol on the page)
4. MasterPage.OnInit
5. Page.OnInit
6. Page.OnInitComplete
7. Page.OnPreLoad
8. Page.OnLoad
9. MasterPage.OnLoad
10. MasterPageControl.OnLoad (for each control on the master page)
11. Control.OnLoad (for each contol on the page)
12. Page.OnXXX (control event)
13. MasterPage.OnBubbleEvent
14. Page.OnBubbleEvent
15. Page.OnLoadComplete
16. Page.OnPreRender
17. MasterPage.OnPreRender
18. MasterPageControl.OnPreRender (for each control on the master page)
19. Control.OnPreRender (for each contol on the page)
20. Page.OnPreRenderComplete
21. MasterPageControl.SaveControlState (for each control on the master page)
22. Control.SaveControlState (for each contol on the page)
23. Page.SaveViewState
24. Page.SavePageStateToPersistenceMedium
25. Page.OnSaveStateComplete
26. MasterPageControl.OnUnload (for each control on the master page)
27. Control.OnUnload (for each contol on the page)
28. MasterPage.OnUnload
29. Page.OnUnload

In order to have dependency injection on your ASP.NET pages, the best way to go is through a customized page handler factory. A page handler factory is a class directly or indirectly derived from PageHandlerFactory who has the responsibility to create a new instance of a Page. What we do is, we call the base class implementation of GetHandler method and then we call IUnityContainer's BuildUp method. Of course, we must also

1. have previously initialized the Unity container, possibly on Application_Start method of Global.asax.cs
2. configure interceptors for the types you want in Web.config. In this example, since I am registering an interface, I will be using InterfaceInterceptor, but you can also use VirtualMethodInterceptor or TransparentProxyInterceptor. I will talk about these in a future post.
3. replace the existing page handler factory with our onw in Web.config

See the attached code, and replace ISomething for your own interface and ConcreteSomething, in Web.config, for the actual implementation of this interface.

The objective behind writing this article is to make use of Ajax Control Toolkit in implementation.

Using a proper MVC pattern to stream an image from Microsoft Chart controls for the Microsoft .NET Framework 3.5.

Enterprise Library comes with several lifetime manager, which you can use to control how your objects are stored and retrieved. The available lifetime managers are:

• ExternallyControlledLifetimeManager: stores a weak reference to objects which are created elsewhere
• PerThreadLifetimeManager: stores objects in a thread static dictionary)
• ContainerControlledLifetimeManager (the default): stores objects in the Unity container
• TransientLifetimeManager: does not store objects, create a new one every time it is requested

In web applications, we may need additional options, for example:

• Store objects in the current session
• Store objects in the current request
• Store objects in the current application

So, I wrote three new lifetime managers, for each of these requirements: WebSessionLifetimeManager, WebRequestLifetimeManager and WebApplicationLifetimeManager. Another possibility would be a pooled lifetime manager, which will be the subject for a future post.
