public static IDisposable BindCommandUnsafe<TView, TViewModel, TProp, TControl>(this TView view, TViewModel? viewModel, Expression<Func<TViewModel, TProp?>> propertyName, Expression<Func<TView, TControl>> controlName, string? toEvent) where TView : class, IViewFor where TViewModel : class where TProp : ICommand where TControl : class

View source

Summary: Binds a command from a view model to a control on a view.

Type parameters

Name	Description
`TView`	The type of the view.
`TViewModel`	The type of the view model.
`TProp`	The type of the command property.
`TControl`	The type of the control.

Parameters

Name	Type	Description
`view`	`TView`	The view to bind to.
`viewModel`	`TViewModel?`	The view model containing the command.
`propertyName`	Expression>	An expression that selects the command property on the view model.
`controlName`	Expression>	An expression that selects the control on the view.
`toEvent`	string?	The event name to bind to. If null, a default event is selected.

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

Remarks

Resolves the property chain by reflection, for an expression the generator could not read.

View source

Summary: Binds a command from a view model to a control on a view with an observable parameter.

Type parameters

Name	Description
`TView`	The type of the view.
`TViewModel`	The type of the view model.
`TProp`	The type of the command property.
`TControl`	The type of the control.
`TParam`	The type of the command parameter.

Parameters

Name	Type	Description
`view`	`TView`	The view to bind to.
`viewModel`	`TViewModel?`	The view model containing the command.
`propertyName`	Expression>	An expression that selects the command property on the view model.
`controlName`	Expression>	An expression that selects the control on the view.
`withParameter`	IObservable	An observable that provides the command parameter.
`toEvent`	string?	The event name to bind to. If null, a default event is selected.

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

Remarks

Resolves the property chain by reflection, for an expression the generator could not read.
