Implementations There are lots of different ways to implement these ideas. ActionMessage bubbles through the Visual Tree searching for a target instance that can handle it.

It would look like this:. Since the ShellView has a TransitioningContentControl bound to the ActiveItem, the activated workspace is injected and its view is shown at that location. Anything that goes through the ViewModelBinder will have its action target set automatically. It is important to note that property injection only works for Interface types.

This cheat sheet covers some of the basic conventions within the framework as well as some additional tools it supplies for scenarios that fall outside what the conventions cover. Caliburn Micro expects a particular naming convention. It has an AttachView method which is called by the framework when it binds the view to the instance. The CustomerViewModel has the ability to show local modal dialogs they are only modal to that specific custom record, not anything else.

The bool property will calibunr if the deactivation is actually a close. The mechanism allows for passing parameters to the method as well. Micgo — A property that indicates what item the conductor is currently tracking as active. Handles provides a convenient way to wrap this logic up and make use of it at the time of requesting. Also, this class ensures that all property change and collection change events occur on the UI thread.


Here we have a simple WPF application with a series of tabs. But, I do want to point out a few interesting implementation details.

But, you could also use this for any number of async tasks. This class is registered as NonShared with MEF so that each portion of the application that wants to display doucmentation modals will get its own instance and be able to maintain its own state, as demonstrated with the CustomerViewModel discussed above.

When a new item is activated, the previous active item is deactivated only and it remains in the Items collection. Such contextual information enables a loosely-coupled, declarative mechanism by which a Presenter or View-Model can communicate with its View without needing to hold a reference to it at any time. SimpleContainer provides the Activate event that is raised when a service socumentation requested from the container and its corresponding implementation is created thus allowing you to perform any custom initialization or operation you wish on the newly created instance.

If you have a property on your ViewModel with the same name as an element, we will attempt to databind them.

BindableCollection is a simple collection that inherits from ObservableCollectionbut that ensures that all its events are raised on the UI thread as well.

Micro are being folded back into Caliburn v2. In our case we should add UserControl.

Rather than take the time to explain what the UI does, have a look at this short video for a brief visual explanation. Each view should end with ‘View’ and start with the same name you calibyrn for the view model. Micro provides the developer with default implementations of IScreen and IConductor. If the Screen is not controlled by a Conductor, but exists independently perhaps because it was shown using the WindowManagerthis method attempts to caliubrn the view. For now, the public definition of SimpleContainer is shown below.


You should now be ready to build your project and check the application has been wired up correctly. Hopefully you see how easy it is to pull your application mico using the framework. To fix the BootStrapper problem: If you are transitioning away from a screen, it makes sure it gets deactivated. Thanks, this calibkrn a really helpful first introduction to Caliburn.

Micro strives to go beyond simply getting it done. These improvements are being introduced back into Caliburn. Versatile software developer in BT Skyrise, specializes in. When you show a screen, the conductor makes sure it is properly activated.

These conventions are based on x: First, we should add the method in the view model:. Finally, we changed our CanSayHello property into a method with the same inputs as the action, but with a bool return type. Finally, it has an event which should be raised when a view is attached to the instance called ViewAttached. So, where does that come from?

This is supported by setting the View.
