Valore proprietàThe requested command. The default key gesture for this command is Ctrl+E.
This command operates at the Paragraph level. If this command is invoked on a partial selection of content within a paragraph (including an empty selection where the caret is within a paragraph), the requested effect will be applied to the entire paragraph. If this command is invoked on a selection that spans multiple paragraphs, the effect will be applied to the entire contents of each paragraph that participates in the selection.
The following figure shows an example of centered content.
This command is natively supported by RichTextBox.
The following example demonstrates how to invoke an editing command on an object that supports the command.
For this example, a RichTextBox serves as the command target. Note that RichTextBox implements the IInputElement interface (inherited from FrameworkElement), and that it includes native support for many editing commands.
The first argument for the Execute method is a command parameter. Most editing commands ignore the command parameter; in general this parameter should be left null for editing commands.
The second argument specifies the object to which the command will be routed. This object must implement the IInputElement interface, and should include a handler for the specified command. Generally, a command is ignored when invoked on an object that does not handle the command.
