Public void SourceInitialized(Window rootWindow) ĭoing so, the DialogService is able to get a hold of root Window, and whichever view-model needs to show a dialog does not create a(n indirect) dependency on main view-model. This way Caliburn will automatically search for the view when loading the view model into memory. So if the view happens to be named MainWindowView then your view model should be named MainWindowViewModel. Public class DialogService : IWindowListener Caliburn Micro is built so that it can predict the view and viewmodel mapping just by the names. DialogService exposes a handler - or interface - as requested by behavior:.InitListener.SourceInitialized(sender as Window) boilerplate code for IWindowListener InitListener dependency propertyĪttachedWindow.SourceInitialized += (sender, evt) => We will learn both methods Show() and ShowDialog() with an example in this c post. we can open a form by two ways Form.Show() and Form.ShowDialog() methods in windows forms application. Public class WindowSourceBehavior : Behavior In this c windows application tutorial we will learn how to open a windows from from another form. Upon event, behavior will notify some handler passed in via attached property: That is the event fired when the window handle is available. The windowmanager is called from ScreenB to create the confirmation window. Implement a behavior that detects Window.OnSourceInitialized event and attach it to main view Window component.if it could cause a dependency loop:ĭialogService (aka RootViewModel) -> SomeViewModel -> RootViewModel.Ī more involved approach to break this dependency chain (and actually invert it) is the following: Sometimes this might not be desiderable, e.g. The Window Manager is used to show dialogs, popups and toast notifications only. When the root/main/shell view-model implements a kind of DialogService interface, every other view-model needing to show dialogs will end up with a dependency on the root view-model. A Silverlight application consists of one root visual only.
