WP8.1 AppBarButton holding event

问题

How do I detect if AppBarButton is being held? There is a Holding event, but it never fires, even if I set AppBarButton's property IsHoldingEnabled to true. Or even when I set CommandBar's IsHoldingEnabled to true.

Try this code within your xaml code for your appbar.

<page.BottomAppBar>
<commandBar>
    <commandBar.PrimaryCommands>
        <appBarButton Label="formatting" 
                      IsHoldingEnabled="True"
                      Holding="AppBarButton_Holding">
            <appBarButton.Icon>
                <pathIcon HorizontalAlignment="Center" VerticalAlignment="Center" Data="Some path"/>
            </appBarButton.Icon>
        </appBarButton>
    </commandBar.PrimaryCommands>

</commandBar>
</page.BottomAppBar>

Hope it helps!
