Interface IReactiveCommand

Namespace
ReactiveUI
Assembly
ReactiveUI.dll

Encapsulates a user action behind a reactive interface. This is for interop inside for the command binding. Not meant for external use due to the fact it doesn't implement ICommand to force the user to favor the Reactive style command execution.

Properties

CanExecute

Gets an observable whose value indicates whether the command can currently execute.

IObservable<bool> CanExecute { get; }

Property Value

IObservable<bool>

The can execute.

Remarks

The value provided by this observable is governed both by any canExecute observable provided during command creation, as well as the current execution status of the command. A command that is currently executing will always yield false from this observable, even if the canExecute pipeline is currently true.

IsExecuting

Gets an observable whose value indicates whether the command is currently executing.

IObservable<bool> IsExecuting { get; }

Property Value

IObservable<bool>

The is executing.

Remarks

This observable can be particularly useful for updating UI, such as showing an activity indicator whilst a command is executing.
