Remarks

XamlUICommand implements the ICommand interface (Windows.UI.Xaml.Input.ICommand for C++ or System.Windows.Input.ICommand for C#), adding various UI properties, methods, and events.

The platform provides the following set of commands.

Command/Label	Description	Icon	Keyboard shortcut
Cut	Delete the selected content and copy it to the clipboard.	E8C6	Ctrl + X
Copy	Copy the selected content to the clipboard.	E8C8	Ctrl + C
Paste	Insert the the clipboard content.	E77F	Ctrl + P
Select All	Select all content.	E8B3	Ctrl + A
Delete	Delete the selected content.	E74D	Delete
Share	Share the selected content.	E72D	n/a
Save	Save changes.	E74E	Ctrl + S
Open	Open panel.	E8A0	Ctrl + O
Close	Close panel.	E89F	Alt + F4
Pause	Pause currently playing media.	E769	Spacebar
Play	Play currently paused media.	E768	Spacebar
Stop	Stop media.	E71A	Escape
Forward	Skip forward.	E72A	Alt + Right arrow
Back	Skip back.	E72B	Alt + Left arrow
Undo	Revert the most recent action.	E7A7	Ctrl + Z
Redo	Repeat the most recently undone action.	E7A6	Ctrl + Y

Constructors

StandardUICommand()	Initializes a new instance of the StandardUICommand class.
StandardUICommand(StandardUICommandKind)	Initializes a new instance of the StandardUICommand class of the specified kind.

Properties

AccessKey	Gets or sets the access key (mnemonic) for this element. (Inherited from XamlUICommand)
Command	Gets or sets the command behavior of an interactive UI element that performs an action when invoked, such as sending an email, deleting an item, or submitting a form. (Inherited from XamlUICommand)
Description	Gets or sets a description for this element. (Inherited from XamlUICommand)
Dispatcher	Gets the CoreDispatcher that this object is associated with. The CoreDispatcher represents a facility that can access the DependencyObject on the UI thread even if the code is initiated by a non-UI thread. (Inherited from DependencyObject)
IconSource	Gets or sets a glyph from the Segoe MDL2 Assets font for this element. (Inherited from XamlUICommand)
KeyboardAccelerators	Gets or sets the collection of key combinations for this element that invoke an action using the keyboard. (Inherited from XamlUICommand)
Kind	Gets the platform command (with pre-defined properties such as icon, keyboard accelerator, and description) that can be used with a StandardUICommand.
KindProperty	Identifies the Kind dependency property.
Label	Gets or sets the label for this element. (Inherited from XamlUICommand)

Methods

CanExecute(Object)	Retrieves whether the command can execute in its current state. (Inherited from XamlUICommand)
ClearValue(DependencyProperty)	Clears the local value of a dependency property. (Inherited from DependencyObject)
Execute(Object)	Invokes the command. (Inherited from XamlUICommand)
GetAnimationBaseValue(DependencyProperty)	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetValue(DependencyProperty)	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
NotifyCanExecuteChanged()	Notifies the system that the command state has changed. (Inherited from XamlUICommand)
ReadLocalValue(DependencyProperty)	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)	Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. (Inherited from DependencyObject)
SetValue(DependencyProperty, Object)	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)	Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject)

Events

CanExecuteChanged	Occurs whenever something happens that affects whether the command can execute. (Inherited from XamlUICommand)
CanExecuteRequested	Occurs when a CanExecute call is made. (Inherited from XamlUICommand)
