Can't find ViewModel for RadWindow using Caliburn.Micro

[Erik]

I'm trying to open a RadWindow in my Caliburn.Micro project, but I'm having trouble tying the dialog's View to the ViewModel.

In my ViewModel I open the dialog using:

var radWindowViewModel = new MyViewModel();
var radWindow = new RadWindow
    {
      Width = 400,
      Height = 150,
      Content = ViewLocator.LocateForModelType(typeof(MyViewModel), null, radWindowViewModel)
   };
radWindow.ShowDialog();

The RadWindow is opened, but in it is displayed: "Cannot find view for MyNameSpace.MyViewModel.

Alternatively, when I set RadWindow.Content the following way:

Content = ViewLocator.LocateForModel(radWindowViewModel, null, null)

then I see the correct View, but the View's DataContext is never set.

Does anyone know what I'm doing wrong?

I was missing the ViewModelBinder:

var radWindowViewModel = new MyViewModel();

var radWindowView = ViewLocator.LocateForModel(radWindowViewModel, null, null);

ViewModelBinder.Bind(radWindowViewModel, radWindowView, null);

 

var radWindow = new RadWindow

{
   Width = 400,

   Height = 150,

    Content = radWindowView

};

radWindow.ShowDialog();

But I now get the following line in the output:
System.Windows.Data Error: 5 : Value produced by BindingExpression is not valid for target property.; Value='<null>' BindingExpression:Path=(0); DataItem='RadWindow' (Name=''); target element is 'WindowHostWindow' (Name=''); target property is 'Title' (type 'String')

Is there an additional step that I'm missing?
