Hierarchy of Viewmodel Base Classes

MugenMvvm has a bunch of base view models for different usage scenarios:

  • ViewModelBase - base class for all ViewModels. Contains methods for creation of others ViewModels, methods for message passing beetwen VMs, properties and method to control the state of async operations (IsBusy, BusyMessage, etc.). Inherits NotifyPropertyChanged.

  • EditableViewModel - inherits ValidatableViewModel, allows to edit and validate models. This viewmodel is tracing the state of model object and allows to undo any changes.

  • WorkspaceViewModel - inherits CloseableViewModel class. Contains properties IsSelected and DisplayName. The first one allows to trace whenever VM was selected. The second one allows to show some useful text on the View through binding on any text property in View's control. Implements IViewAwareViewModel interface that allows to work with View through IView View property. Implements INavigableViewModel interface that allows to control navigation of ViewModel (through methods OnNavigatingFrom, OnNavigatedFrom, OnNavigatedTo).
