How do I bind the visibility of a button to a bool value in my ViewModel?
<Button Height="50" Width="50" Style="{StaticResource MyButtonStyle}"
Command="{Binding SmallDisp}" CommandParameter="{Binding}" Cursor="Hand"
Visibility="{Binding Path=AdvancedFormat}" />
Since Windows 10 15063 upwards
Since Windows 10 build 15063, there is a new feature called "Implicit Visibility conversion" that binds Visibility to bool value natively - There is no need anymore to use a converter.
My code (which supposes that MVVM is used, and Template 10 as well):
<!-- In XAML -->
<StackPanel x:Name="Msg_StackPanel" Visibility="{x:Bind ViewModel.ShowInlineHelp}" Orientation="Horizontal" Margin="0,24,0,0">
<TextBlock Text="Frosty the snowman was a jolly happy soul" Margin="0,0,8,0"/>
<SymbolIcon Symbol="OutlineStar "/>
<TextBlock Text="With a corncob pipe and a button nose" Margin="8,0,0,0"/>
</StackPanel>
<!-- in companion View-Model -->
public bool ShowInlineHelp // using T10 SettingsService
{
get { return (_settings.ShowInlineHelp); }
set { _settings.ShowInlineHelp = !value; base.RaisePropertyChanged(); }
}
