Methods

GetViewForViewModelDynamic(Type)

Like GetViewForViewModel<TViewModel>(TViewModel), but accepts a Type parameter instead of an instance.

public Type? GetViewForViewModelDynamic(Type viewModelType)

Parameters

viewModelType Type

Returns

Type

GetViewForViewModel<TViewModel>(TViewModel)

Retrieves the registered View type for a given ViewModel type, or null if no registration exists.

public Type? GetViewForViewModel<TViewModel>(TViewModel viewModel) where TViewModel : INotifyPropertyChanged

Parameters

viewModel TViewModel

Returns

Type

Type Parameters

TViewModel

RegisterDynamic(Type, Type, bool)

Like Register<TViewModel, TComponent>(bool), but accepts Type parameters instead of generics.

Note that there are no runtime checks for the constraints that apply to the generic version of this method to allow usage with e.g. AOT compilation.

public void RegisterDynamic(Type viewModelType, Type componentType, bool noWarn = false)

Parameters

viewModelType Type

componentType Type

noWarn bool

Register<TViewModel, TComponent>(bool)

Registers a View type for a given ViewModel type. TComponent must be an MvvmComponentBase<T>, not with an optional or owned viewmodel, because we pass a non-null ViewModel instance to the component when rendering. Without that constraint, it would be possible to register a component that doesn't accept the ViewModel as a parameter.

You may prefer using the source generator - see ViewModelForAttribute.

If you are not using trimming (enabled by default in Blazor WASM since .NET 6 with dotnet publish) or AOT compilation, you may prefer using AutoRegister() for automatic registration. Otherwise, use this method to manually register all View/ViewModel pairs.

public void Register<TViewModel, TComponent>(bool noWarn = false) where TViewModel : INotifyPropertyChanged where TComponent : MvvmComponentBase<TViewModel>

Parameters

noWarn bool

Type Parameters

TViewModel

TComponent
