Properties
| AccessKey |
Gets or sets the access key (mnemonic) for this element. (Inherited from XamlUICommand) |

| 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 |

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
