Package:

Xamarin.CommunityToolkit v1.1.0

An implementation of IAsyncValueCommand. Allows Commands to safely be used asynchronously with Task.

C#‎

public class AsyncValueCommand : Xamarin.CommunityToolkit.ObjectModel.Internals.BaseAsyncValueCommand<object,object>, System.Windows.Input.ICommand, Xamarin.CommunityToolkit.ObjectModel.IAsyncValueCommand

Inheritance

System.Object

BaseCommand<TCanExecute>

BaseAsyncValueCommand<System.Object,System.Object>

AsyncValueCommand

Implements

System.Windows.Input.ICommand IAsyncValueCommand

Constructors

AsyncValueCommand(Func<ValueTask>, Func<Boolean>, Action<Exception>, Boolean, Boolean)	Initializes a new instance of AsyncValueCommand
AsyncValueCommand(Func<ValueTask>, Func<Object,Boolean>, Action<Exception>, Boolean, Boolean)	Initializes a new instance of AsyncValueCommand

Properties

AllowsMultipleExecutions	Returns true if the Command allows simultaneous executions (Inherited from BaseCommand<TCanExecute>)
ExecutionCount	(Inherited from BaseCommand<TCanExecute>)
IsExecuting	Returns true when the Command is currently executing. Returns false when the Command is not executing (Inherited from BaseCommand<TCanExecute>)

Methods

CanExecute(TCanExecute)	Determines whether the command can execute in its current state (Inherited from BaseCommand<TCanExecute>)
ChangeCanExecute()	Raises the ICommand.CanExecuteChanged event. Recommend using RaiseCanExecuteChanged() instead. (Inherited from BaseCommand<TCanExecute>)
ExecuteAsync()	Executes the Command as a ValueTask
RaiseCanExecuteChanged()	Raises the ICommand.CanExecuteChanged event. (Inherited from BaseCommand<TCanExecute>)

Events

CanExecuteChanged

Occurs when changes occur that affect whether or not the command should execute (Inherited from BaseCommand<TCanExecute>)

Explicit Interface Implementations

ICommand.CanExecute(Object)	(Inherited from BaseAsyncValueCommand<TExecute,TCanExecute>)
ICommand.Execute(Object)	(Inherited from BaseAsyncValueCommand<TExecute,TCanExecute>)
