NavigationAware

Apply [NavigationAware] to a partial class that references Prism.Navigation.Regions.INavigationAware (via Prism.Core) to emit navigation lifecycle members.

Usage

using Prism.Mvvm;
using Prism.Navigation.Regions;
using Prism.SourceGenerators;

[NavigationAware]
public partial class DashboardViewModel : BindableBase
{
    partial void OnNavigatedToCore(NavigationContext navigationContext)
    {
        // Called when the view enters the region.
    }
}

Generated members

• OnNavigatedTo → calls OnNavigatedToCore
• IsNavigationTarget → calls IsNavigationTargetCore (default true in generated partial)
• OnNavigatedFrom → calls OnNavigatedFromCore
