WP8.1命令栏（appbar）粘滞问题

Question

I would like to create a commandbar (former appbar) that is not getting closed when the user presses one of the primary command buttons. When i got it right, the "issticky"-property should make this behavior possible.

My XAML Code:

<Page.BottomAppBar>
    <CommandBar x:Name="bottomCommandBar" IsSticky="True" ClosedDisplayMode="Minimal">
        <CommandBar.PrimaryCommands>
            <AppBarButton x:Name="button1" Label="Button1" Tapped="Button1_Tapped">
                <AppBarButton.Icon>
                    <PathIcon Data=""/>
                </AppBarButton.Icon>
            </AppBarButton>
            <AppBarButton x:Name="button2" Label="Button2" Tapped="Button2_Tapped">
                <AppBarButton.Icon>
                    <PathIcon Data=""/>
                </AppBarButton.Icon>
            </AppBarButton>
        </CommandBar.PrimaryCommands>
    </CommandBar>
</Page.BottomAppBar>

IsSticky = true doesn't work, i also tested to set it in the button tapped event handler.

What is the regular way of getting this behavior? Or does anyone know a 'workaround'?
I would be grateful for any suggestions!
Best,

Answer 1

Change the ClosedDisplayMode to Compact or remove it from the CommandBar definition (it's the default).

<CommandBar x:Name="bottomCommandBar" ClosedDisplayMode="Compact">

or

<CommandBar x:Name="bottomCommandBar">

Answer 2

在页面加载中尝试一下

((AppBar)bottomCommandBar).IsSticky = true;
