Constructors
| DelegateCommand<T>(Action<T>, JoinableTaskFactory) |
Initializes a new instance of the DelegateCommand<T> class. Using this constructor to initialize the DelegateCommand results in a command that can always execute. |
| DelegateCommand<T>(Action<T>, Predicate<T>, JoinableTaskFactory) |
Initializes a new instance of the DelegateCommand<T> class. |
| DelegateCommand<T>(Action<T>, Predicate<T>) |
Initializes a new instance of the DelegateCommand<T> class. |
| DelegateCommand<T>(Action<T>) |
Initializes a new instance of the DelegateCommand<T> class. Using this constructor to initialize the DelegateCommand results in a command that can always execute. |
Methods
| CanExecute(Object) |
Gets a value indicating whether this command is executable. |
| CanExecuteDependsOn(INotifyPropertyChanged, String) |
Adds a property upon which this command's CanExecute state depends. When the property changes, this command will raise CanExecuteChanged (Inherited from DelegateCommandBase) |
| Execute(Object) |
Executes the command. |
| RaiseCanExecuteChanged() |
Raises the CanExecuteChanged event. (Inherited from DelegateCommandBase) |
Events
| CanExecuteChanged |
An event that is fired when the executable state of this command changes. Call RaiseCanExecuteChanged to force listeners to update. (Inherited from DelegateCommandBase) |
