EditingCommands.SelectLeftByWord Property

Represents the SelectLeftByWord command, which requests that the current selection be expanded left by one word.

Namespace: System.Windows.Documents
Assembly: PresentationFramework (in presentationframework.dll)
XML Namespace:

public static RoutedUICommand SelectLeftByWord { get; }
/** @property */
public static RoutedUICommand get_SelectLeftByWord ()

public static function get SelectLeftByWord () : RoutedUICommand

<object property="SelectLeftByWord"/>

Property Value

The requested command. The default key gesture for this command is Ctrl+Shift+Left.

If the caret is within a word, this command expands the selection to the beginning of that word. Otherwise, this command expands the selection to the beginning of the previous word.

The expanded selection will not include the word delimiter. Contrast with SelectRightByWord, which does include the word delimiter in the expanded selection.

There is not necessarily an actual implementation that responds to this command on any given object; in many cases the implementation that responds to a command is the responsibility of the application writer.

This command is natively supported by RichTextBox, TextBox, and PasswordBox.

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.

RichTextBox rTB = new RichTextBox();

EditingCommands.ToggleInsert.Execute(null, rTB);
