View source

Summary: Binds the specified view model property to the given view property.

Type parameters

Name	Description
`TViewModel`	The type of the view model being bound.
`TView`	The type of the view being bound.
`TVMProp`	The type of the property bound on the view model.
`TVProp`	The type of the property bound on the view.

Parameters

Name	Type	Description
`view`	`TView`	The instance of the view to bind.
`viewModel`	`TViewModel?`	The instance of the view model to bind.
`vmProperty`	Expression>	An expression indicating the property that is bound on the view model. This can be a chain of properties of the form. `vm => vm.Foo.Bar.Baz` and the binder will attempt to subscribe to changes on each recursively.
`viewProperty`	Expression>	The property on the view that is to be bound. This can be a chain of properties of the form. `view => view.Foo.Bar.Baz` and the binder will attempt to set the last one each time the view model property is updated.
`conversionHint = null`	object?	An object that can provide a hint for the converter. The semantics of this object is defined by the converter used.
`vmToViewConverterOverride = null`	[IBindingTypeConverter?](#	An optional [IBindingTypeConverter](# to use when converting from the viewModel to view property.
`viewToVMConverterOverride = null`	[IBindingTypeConverter?](#	An optional [IBindingTypeConverter](# to use when converting from the view to viewModel property.

Returns: IReactiveBinding -- An instance of IDisposable that, when disposed, disconnects the binding.

View source

Summary: Binds the specified view model property to the given view property, and provide a custom view update signaller to signal when the view property has been updated.

Type parameters

Name	Description
`TViewModel`	The type of the view model being bound.
`TView`	The type of the view being bound.
`TVMProp`	The type of the property bound on the view model.
`TVProp`	The type of the property bound on the view.
`TDontCare`	A dummy type, only the fact that `signalViewUpdate` emits values is considered, not the actual values emitted.

Parameters

Name	Type	Description
`view`	`TView`	The instance of the view to bind.
`viewModel`	`TViewModel?`	The instance of the view model to bind.

`viewProperty`	Expression>	The property on the view that is to be bound. This can be a chain of properties of the form. `view => view.Foo.Bar.Baz` and the binder will attempt to set the last one each time the view model property is updated.
`signalViewUpdate`	IObservable?	An observable, that when signaled, indicates that the view property has been changed, and that the binding should update the view model property accordingly.
`conversionHint = null`	object?	An object that can provide a hint for the converter. The semantics of this object is defined by the converter used.
`vmToViewConverterOverride = null`	[IBindingTypeConverter?](#	An optional [IBindingTypeConverter](# to use when converting from the viewModel to view property.
`viewToVMConverterOverride = null`	[IBindingTypeConverter?](#	An optional [IBindingTypeConverter](# to use when converting from the view to viewModel property.
`triggerUpdate = 0`	[TriggerUpdate](#	The trigger update direction.

Returns: IReactiveBinding -- An instance of IDisposable that, when disposed, disconnects the binding.
