I have an issue with command bar: I use template10, so my CommandBar is in a Grid on bottom of page. I set the property ClosedDisplayMode to Minimal. But the grid has a Visibility=Collapsed by default. When I switch the grid visibility to Visible, the CommandBar appears but the more button is not visible, the command bar is empty. However, the more button is here because I can click it. And when I have click on it at least one time, the content of the button ("...") appears. I hope this is clear...
EDIT 2
Here is the way to reproduce issue:
1 - Create new blank universal app project (without template10)
2 - Replace the XAML code in MainPage.xaml by the following:
<Page
x:Class="BlankAppBarMoreButtonHidden.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:BlankAppBarMoreButtonHidden"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Button Content="Show app bar"
x:Name="btnShowAppBar"
Click="btnShowAppBar_Click"/>
<Grid Grid.Row="1"
x:Name="appBar"
Visibility="Collapsed">
<CommandBar ClosedDisplayMode="Minimal">
<CommandBar.SecondaryCommands>
<AppBarButton Label="Commande 1"/>
<AppBarButton Label="Commande 2"/>
</CommandBar.SecondaryCommands>
</CommandBar>
</Grid>
</Grid>
3 - Add event implementation in the code behind:
private void btnShowAppBar_Click(object sender, RoutedEventArgs e)
{
appBar.Visibility = Visibility.Visible;
}
4 - Finally, run the project. And press the button. The command bar appears but the more button is not visible. However you click it (clicking on its expected place in bottom right of page) and at this moment, the content appears.
