ViewModel binding context within DataTemplate #10213

Astech created 3 years ago

Hi,

When I include the ContentPage.BindingContext on my page, the app crashes when trying to load the page.

<ContentPage.BindingContext>
    <local:TeamsView />
</ContentPage.BindingContext>

` I'm trying to use OpenContextMenu command which is a command inside my viewmodel.

    <Button Text="{StaticResource VerticalEllipsisIcon}"
        FontFamily="{StaticResource IconsFont}"
        Command="{Binding BindingContext.OpenContextMenuCommand}"
        CommandParameter="{Binding}"
        TextColor="DarkGray"
        BackgroundColor="Transparent"
        VerticalOptions="Center"

The viewmodel command: public TeamsViewModel(ITeamsAppService teamsAppService) { _teamsAppService = teamsAppService;

        OpenContextMenuCommand = new Command<TeamModel>(item => item.IsPopupOpen = !item.IsPopupOpen);
        Teams = new ObservableRangeCollection<TeamModel>();
    }

    public Command<TeamModel> OpenContextMenuCommand { get; }
