Caliburn.Micro视图切换

Question

In a CM WPF application I have following items:

<Window> <!-- Shell Window -->
 <ContentControl x:Name="MainRegion">
 <ContentControl x:Name="SearchRegion">
<Window>

Views:

MainRegionView
SearchRegionView

View Models:

MainRegionViewModel //implements Conductor<Screen>
SearchRegionViewModel //implements Conductor<Screen>

I neet to switch the view of SearchRegionViewModel from MainRegionViewModel. Following code is executed inside MainRegionViewModel .

ViewModelTest test = new ViewModelTest();
//Calling the method from object reference
searchRegionViewModel.ActivateItem(test);

Problem: the view is not loaded in SearchRegionView. How can i load the view to SearchRegion?

Answer 1

Your MainRegionViewModel & SearchRegionView need to implement Screen and your ShellViewModel is the one that need to implement the Conductor. After that, you need to bind the ActiveItem in the XAML (ShellView.xaml).

<ContentControl x:Name="ActiveItem"></ContentControl>

Inside your ShellViewModel use Activate(YourViewModel) .

Here is an Example

If you want to change the ActiveItem inside your MainRegionViewModel, You need to look at the EventAggregator to publish a message to your ShellViewModel to Activate the desire ViewModel
