AsyncCommand

Implements

System.Windows.Input.ICommand IAsyncCommand

Constructors

AsyncCommand(Func<Task>, Func<Boolean>, Action<Exception>, Boolean, Boolean)	Initializes a new instance of AsyncCommand
AsyncCommand(Func<Task>, Func<Object,Boolean>, Action<Exception>, Boolean, Boolean)	Initializes a new instance of AsyncCommand

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 Task
RaiseCanExecuteChanged()	Raises the ICommand.CanExecuteChanged event. (Inherited from BaseCommand<TCanExecute>)
