XAML StandardUICommand.Kind

I'm in the process of learning the new Windows SDK Preview. This SDK has made it possible to set the Kind property of a StandardUICommand. The StandardUICommand was added in the 1809 SDK (17763) but the StandardUICommandKind property was readonly which made it impossible to use from XAML. You could only set the Kind using a constructor parameter in code. Now you can define the StandardUICommand in XAML inside your AppBarButton, MenuFlyoutItem and MenuBarItem.

Demo

I have created a small demo page with a CommandBar and a DropDownButton (also new in the 1809 SDK). The CommandBar has 2 AppBarButton controls (Undo & Redo). The Command property of these buttons are set to a StandardUICommand with the Kind values 'Undo' and 'Redo'. The DropDownButton has a flyout menu with 3 FlyoutMenuItems in it. The Commands of these items are also set to a StandardUICommands. The StandardUICommand will set the Icon, Label/Text, Tooltip and KeyboardAccelerator of the button/item.

The possible value for Kind are:

• None
• Cut
• Copy
• Paste
• SelectAll
• Delete
• Share
• Save
• Open
• Close
• Pause
• Play
• Stop
• Forward
• Backward
• Undo
• Redo

                        </MenuFlyoutItem.Command>
                    </MenuFlyoutItem>
                    <MenuFlyoutItem>
                        <MenuFlyoutItem.Command>
                            <StandardUICommand Kind="Delete" />
                        </MenuFlyoutItem.Command>
                    </MenuFlyoutItem>
                </MenuFlyout>
            </DropDownButton.Flyout>
        </DropDownButton>
    </Grid>
</Page>

Closure

It is great that the Kind property can now be set. This saves me a lot of work setting the Icon, Label/Text, Tooltip and KeyboardAccelerator of AppBarButtons and MenuItems manually.
