To inject a view into a popup window in Prism, you can follow these steps:

  1. Create a new Prism module that contains the view you want to display in the popup window.
  2. Implement a view model for the view that will be displayed in the popup window.
  3. Create a new Prism region within the popup window where you want to display the view. You can do this by adding a ContentControl or another appropriate control to the popup window's XAML and then defining the region in your code.
  4. Register the view and view model with the Prism container in your module's Initialize method.
  5. Resolve the view and view model from the container and set them as the region's content when the popup window is opened.


Here is a simple example of how you can inject a view into a popup window using Prism:

// Module that contains the view for the popup window
public class PopupModule : IModule
{
    private readonly IRegionManager _regionManager;
    
    public PopupModule(IRegionManager regionManager)
    {
        _regionManager = regionManager;
    }

    public void Initialize()
    {
        // Register the view and view model
        _container.RegisterTypeForNavigation<PopupView, PopupViewModel>();

        // Create a region within the popup window
        _regionManager.RegisterViewWithRegion("PopupRegion", typeof(PopupView));
    }
}

// In your popup window code-behind or view model
private void OpenPopupWindow()
{
    // Resolve the view and view model from the container
    var view = _container.Resolve<PopupView>();
    var viewModel = _container.Resolve<PopupViewModel>();

    // Set the view model as the data context for the view
    view.DataContext = viewModel;

    // Get the region in the popup window and set the view as its content
    var region = _regionManager.Regions["PopupRegion"];
    region.Add(view);
}


By following these steps, you can successfully inject a view into a popup window in a Prism application.
