ListBox and WhenActivated

[ctrl-alt-d]

I use a ListBox to show items as "rows", each item has a UserControl with a ViewModel.

This is how I'm registering the handler to open the edit dialog on each row:

        public CentreRowUserCtrl()
        {
            InitializeComponent();
            this.WhenActivated(d => d(ViewModel!.ShowDialog.RegisterHandler(UpdateShowDialogAsync)));
        }

I guess they are some issues with virtualization and only the firsts ViewModel!.ShowDialog's are bound. Also, the whole row remains on gray when I click the menu. Some other rows also become gray I don't know why, but I suspect all is related with virtualization:

How can I fix it? All run fine if I use ItemsControl instead ListBox, but, they are serious performance issues with ItemsControl: #6417

Was your question answered with #6427 ?

[ctrl-alt-d]

#6427 closes this issue. Using

this.WhenActivated(disposables => {
    this.WhenAnyValue(x => x.ViewModel)
        .Subscribe(vm => { /* Here you can access the view model safely. */ })
        .DisposeWith(disposables);
});

Was the solution.
