BindCommand<TView, TViewModel, TProp, TControl, TParam>(TViewModel?, TView, Expression<Func<TViewModel, TProp?>>, Expression<Func<TView, TControl>>, IObservable<TParam?>, string?)
Bind a command from the ViewModel to an explicitly specified control on the View.
public IReactiveBinding<TView, TProp> BindCommand<TView, TViewModel, TProp, TControl, TParam>(TViewModel? viewModel, TView view, Expression<Func<TViewModel, TProp?>> vmProperty, Expression<Func<TView, TControl>> controlProperty, IObservable<TParam?> withParameter, string? toEvent = null) where TView : class, IViewFor where TViewModel : class where TProp : ICommandParameters
viewModelTViewModelThe View model.
viewTViewThe View.
vmPropertyExpression<Func<TViewModel, TProp>>The ViewModel command to bind.
controlPropertyExpression<Func<TView, TControl>>The name of the control on the view.
withParameterIObservable<TParam>The ViewModel property to pass as the param of the ICommand.
toEventstringIf specified, bind to the specific event instead of the default. NOTE: If this parameter is used inside WhenActivated, it's important to dispose the binding when the view is deactivated.
Returns
- IReactiveBinding<TView, TProp>
A class representing the binding. Dispose it to disconnect the binding.
Type Parameters
TViewThe view type.
TViewModelThe view model type.
TPropThe property type.
TControlThe control type.
TParamThe parameter type.
