Excuse me Geert, a really stupid question but I can't remember how it's done. if I need to fill on the MainView a ContentPresenter and bind it to a viewmodel, how do I render the view? I mean on the MainViewModel I have the viewmodel I need to show. on the MainView.Xaml I've added the ContentPresenter and it binds to a Content property. what I'm missing is the type of the property...has it to be an IView? and resolved via IViewLocator or its something that does the magic?

almost 4 years I write here, and still have got problem pasting code...LOL
/// <summary>
/// Dependencia para crear propiedad ContentControlBag. Nos permite mantener aislado el ContentControl de la vista modelo.
/// </summary>
public static readonly DependencyProperty ContentControlBagPropiedad = DependencyProperty.Register("ContentControlBag", typeof(ContentControlBag),
typeof(MainWindow), new PropertyMetadata(null, (sender, e) => ((MainWindow)sender).UpdateContentControl()));
/// Dependencia para crear propiedad ContentControlBag. Nos permite mantener aislado el ContentControl de la vista modelo.
/// </summary>
public static readonly DependencyProperty ContentControlBagPropiedad = DependencyProperty.Register("ContentControlBag", typeof(ContentControlBag),
typeof(MainWindow), new PropertyMetadata(null, (sender, e) => ((MainWindow)sender).UpdateContentControl()));
private void UpdateContentControl()
{
if (ContentControlBag != null)
{
contenedorVistas.Content = null;
GC.Collect(); // necesario para que se limpie el contenedor de vistas
contenedorVistas.Content = ContentControlBag.View;
contenedorVistas.DataContext = ContentControlBag.ViewModel;
}
}
public ContentControlBag ContentControlBag
{
get { return (ContentControlBag)GetValue(ContentControlBagPropiedad); }
set { SetValue(ContentControlBagPropiedad, value); }
}
this binds the view model and view to the content property..its a dependency property on the view
and this is all i need on the viewmodel
ContentControlBag = new ContentControlBag(Activator.CreateInstance(_view), _viewmodel);
_viewmodel is an instance created by the typeFactory
and _view is the type of the view
so i have to manually close the last vm shown on the ContentPresenter in the MainViewModel. Hope the code gives you a hint to make your own :)
I'm afraid it's internal
no problem,thanks
I think I have to modify the ShellService in order to intercept it
then subscirbe to the close event, I think you can intercept it
I try, thanks
that's because the window depends on the shell implementation (mahapps / fluent.ribbon / whatever)
true
thx for the hint
CloseApplicationWatcherBase
just implement a watcher deriving from that one
and register it in the servicelocator with RegisterAndInstantiate<MyWatcher>()
you should ask your company to sponsor us ;-)
I promise
anyway, this watcher is very nice
you can handle it there
so in our internal libs, we have created a watcher that intercepts that closing, and exposes that via a service, so we can prevent closing from basically everywhere
