        DataContext = this;
        Staff_Show = new ObservableCollection<Staff>();
    }

but it doesn't work.

Answer 1

var whateverPage = new WhateverPage(whateverDataYouWantToPass);
this.NavigationService.Navigate(whateverPage);

Just make sure, the constructor for WhateverPage (the page you are navigating to) is overloaded to accept the item you are passing into it like this:

public WhateverPage(WhateverData data)
{
    // code here
}

So in your case, if you are navigating to a page called Page2 , then you will create a constructor in that page like this:

public Page2(ObservableCollection<Staff> staff)
{
    // Now you have staff in Page2. You can assign it to a property or field
}
