From Listview to Slider showing details

Have a Listview and with SelectedItemChangedEvent the details are showing on other page

Works fine.

But i found a Slider and is it possible to show the details in the Slider on the same page as the Listview and not on the other page ?

Fill the Listview from a Firebase database.

The Slider i made

Go to other page and show the details

async  void lstBal_ItemSelected(System.Object sender, Xamarin.Forms.SelectedItemChangedEventArgs e)
        {

                if (e.SelectedItem != null)
                {
                    await Navigation.PushAsync(new Waar
                    {
                        BindingContext = e.SelectedItem as Person
                    });
                lstBal.SelectedItem = null;
            }

        }
