The following example shows how to set up a MenuItem so that when it is clicked it will invoke the Paste command on a TextBox, assuming the TextBox has keyboard focus. And the MenuItem class has native support for invoking commands. The TextBox control has built in logic for handling the Paste command. The Paste command is one of the predefined commands in the ApplicationCommands class. The simplest way to use a command in WPF is to use a predefined RoutedCommand from one of the command library classes use a control that has native support for handling the command and use a control that has native support for invoking a command. When an application handles the Executed event, it has access to the target of the command and can take appropriate action depending on the target's type. A text object may cut the selected text into the clipboard, while an image object may cut the selected image.

A RoutedCommand enables clients to implement the logic. The key combination CTRL+X invokes the Cut command in text classes, image classes, and Web browsers, but the actual logic for performing the Cut operation is defined by the application that performs the cut. The semantics of a command can be consistent across applications and classes, but the logic of the action is specific to the particular object acted upon. A button can subscribe to the CanExecuteChanged event and be disabled if CanExecute returns false or be enabled if CanExecute returns true. A command can indicate whether an action is possible by implementing the CanExecute method. To indicate this to the user, many applications disable buttons and menu items so that the user knows whether it is possible to perform an action. If a user tries to cut an object or text without having anything selected, nothing would happen.

To continue the example of cutting an object or text, the action only makes sense when something is selected. By using commands, you can bind each type of user action to the same logic.Īnother purpose of commands is to indicate whether an action is available. An application might allow a user to cut selected objects or text by either clicking a button, choosing an item in a menu, or using a key combination, such as CTRL+X. For example, the editing operations Copy, Cut, and Paste, which are found in many applications, can be invoked by using different user actions if they are implemented by using commands. This allows for multiple and disparate sources to invoke the same command logic, and it allows the command logic to be customized for different targets. The first purpose is to separate the semantics and the object that invokes a command from the logic that executes the command. This topic contains the following sections:Ĭommands have several purposes. This overview defines what commands are in WPF, which classes are part of the commanding model, and how to use and create commands in your applications. Examples of commands are the Copy, Cut, and Paste operations found on many applications.

Commanding is an input mechanism in Windows Presentation Foundation (WPF) which provides input handling at a more semantic level than device input.
