MovieList[0] will be a list of movies of Comedy genre, and so on Now I want to bind this List of Lists MovieList object to a ListView in XAML. The ListView ItemSource is to be bound to this MovieList object and each ListViewItem of this ListView will be a ListView itself, bound to the list of movies of a particular genre. ex. list of movies of comedy genre. Further each ListViewItem of this inner List will be bound to the Title property of that particular movie. Please help me out in designing the XAML Code for this.

推荐答案

MVVM 解决方案：

主窗口：

var moviesView = new MoviesView();
moviesView.DataContext = new MoviesViewModel { MovieList = ... };

MoviesViewModel.cs：

public class MoviesViewModel
{
    public ObservableCollection<List<Movie>> MovieList 
    { 
        get; 
        set; 
    }
}

MoviesView.xaml

<ListView ItemsSource="{Binding MovieList}">
   <ListView.ItemTemplate>
      <DataTemplate>
            <ListView ItemsSource="{Binding}">
               <ListView.ItemTemplate>
                   <DataTemplate>
                         <TextBlock Text="{Binding Title}" />
                   </DataTemplate>
               </ListView.ItemTemplate>
            </ListView>
      </DataTemplate>
   </ListView.ItemTemplate>
</ListView>
