1. Overload¶

public static IDisposable BindInteraction<TViewModel, TView, TInput, TOutput>(this TView view, TViewModel? viewModel, Expression<Func<TViewModel, IInteraction<TInput, TOutput>>> propertyName, Func<IInteractionContext<TInput, TOutput>, Task> handler, string propertyNameExpression = "", string callerFilePath = "", int callerLineNumber = 0) where TViewModel : class where TView : class, IViewFor

View source

Summary: Binds a task-based handler to an interaction exposed by the view model.

Type parameters

Name	Description
`TViewModel`	The type of the view model.
`TView`	The type of the view.
`TInput`	The type of the interaction's input.
`TOutput`	The type of the interaction's output.

Parameters

Name	Type	Description
`view`	`TView`	The view that provides the handler.
`viewModel`	`TViewModel?`	The view model that exposes the interaction.
`propertyName`	Expression>>	An expression that selects the interaction property on the view model.
`handler`	Func, Task>	A task-based handler for the interaction.
`propertyNameExpression = ""`	string	The caller argument expression for `propertyName`. Auto-populated by the compiler.
`callerFilePath = ""`	string	The source file path of the caller. Auto-populated by the compiler.
`callerLineNumber = 0`	int	The source line number of the caller. Auto-populated by the compiler.

Returns: IDisposable -- A disposable that, when disposed, disconnects the binding.

Parameters

Name	Type	Description
`view`	`TView`	The view that provides the handler.
`viewModel`	`TViewModel?`	The view model that exposes the interaction.
`propertyName`	Expression>>	An expression that selects the interaction property on the view model.
