Wpf raise event from viewmodel. Learn the best practices with real code examples. That event handler should be in the view model of the view, because it contains business 1) What kind of event is happening in the subview? 2) The subview has a reference to its viewmodel. You subscribe to events. Here's a general approach: The solution is basic OOP design and it is not related to MVVM. In Model-View-ViewModel (MVVM) architecture, the ViewModel should not have direct references to the View in order to maintain separation of concerns. The best open source one I know of in the WPF world is the one in Caliburn Micro. SearchJobVM = new SearchJobViewModel(); this. I'm not sure if you would model it the way you are - with an event. JobDetailsVM Suppose a view contains my user control that fires events, and I want to add an event handler to that event. The sub-viewmodel would then raise an The event doesn't actually force any code to call the property getter; it's just that anyone who bothered to subscribe to the event is almost certainly going to call that method when the event is raised. But you can do things like raise an event on your viewmodel, intercept this on the view, and then perform an action in response to the Most MVVM frameworks have one. However, there are scenarios where you may need . My primary candidate for any viewmodel <-> view communication would be binding. This is a weak event pattern, late binding and the view doesn't need to be aware of what type the Here's how you can achieve event binding to ViewModel methods in WPF: I don't know if really the routed events are the best way to solve it or if there is another options. If there is better options, I would thank to know, but I would like to know why this solution I have a WPF application that uses MVVM The MainWindowViewModel has references to other ViewModels like so:- this. Of In WPF, you can bind events from the View (UI) to the corresponding event handlers in the ViewModel using the Command pattern and ICommand interface. Whenever something interesting happens in Model, fire en event. In C# you just don't pass events. I would have the view call a method on its own viewmodel. You can than Discover how to raise events from your `ViewModel` to your `View` in WPF without breaking the MVVM pattern. You subscribe to some kind of message in one view model and then send the event WPF MVVM Correct way to fire event on view from ViewModelIn my WPF application I have 2 Windows (both Windows Dive into the concept of MVVM events in WPF and learn techniques for effective event handling in your applications.
