DelegateCommand(Action, Func<Boolean>)

Initializes a new instance of the DelegateCommand class.

DelegateCommand(Action, Func<Boolean>, JoinableTaskFactory)

Initializes a new instance of the DelegateCommand class.

DelegateCommand(Action<Object>)

Initializes a new instance of the DelegateCommand class. Using this constructor to initialize the DelegateCommand results in a command that can always execute.

DelegateCommand(Action<Object>, Predicate<Object>)

Initializes a new instance of the DelegateCommand class.

DelegateCommand(Action<Object>, Predicate<Object>, JoinableTaskFactory)

Initializes a new instance of the DelegateCommand class.

Methods

CanExecute(Object)

Gets a value indicating whether this command is executable.

Execute(Object)

Executes the command.

RaiseCanExecuteChanged()

Event called when the current command's ability to execute may have changed.

RaiseCanExecuteChanged()

Raises the CanExecuteChanged event.
