WPF中的网格面板元素是否有数据窗口？

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

public class MainViewModel : INotifyPropertyChanged
{
    public ObservableCollection<Person> People { get; set; }
        = new ObservableCollection<Person>
        {
            new Person { Name = "Alice", Age = 30 },
            new Person { Name = "Bob", Age = 25 },
            new Person { Name = "Charlie", Age = 22 }
        };

    // INotifyPropertyChanged implementation
    // ...
}

   <local:MainViewModel />
</Window.DataContext>
