C# Class Zetbox.Client.WPF.Commands.SmartRoutedUICommand

This abstract class is a RoutedCommand which allows its subclasses to provide default logic for determining if they can execute and how to execute. To enable the default logic to be used, set the IsCommandSink attached property to true on the root element of the element tree which uses one or more SmartRoutedCommand subclasses.

Method Details

CanExecuteCore() protected abstract méthode

Child classes override this method to provide logic which determines if the command can execute. This method will only be invoked if no element in the tree indicated that it can execute the command.

protected abstract CanExecuteCore ( object parameter ) : bool
parameter	object	The command parameter (optional).
Résultat	bool

ExecuteCore() protected abstract méthode

Child classes override this method to provide default execution logic. This method will only be invoked if CanExecuteCore returns true.

protected abstract ExecuteCore ( object parameter ) : void
parameter	object	The command parameter (optional).
Résultat	void
