我正在将电影列表显示为我的 Windows Phone 7 应用程序的全景图。单击每部电影正在显示电影详细信息,演员表。电影细节,演员表显示为枢轴控件。电影细节效果很好但是当我展示演员时,它不起作用。我有演员表。并将源绑定到 cast pivot 控件中的列表框,但它不显示任何数据。请帮我。以下是我使用过的课程。谢谢
主视图模型.cs
public class MainViewModel
{
public ObservableCollection<ItemViewModel> MovieItems { get; set; }
}
项目视图模型.cs
public class ItemViewModel : INotifyPropertyChanged
{
private string _title;
public string _Title
{
get { return _title; }
set
{
if (value != _title)
{
_title = value;
NotifyPropertyChanged("title");
}
}
}
private ObservableCollection<Cast> _cast;
public ObservableCollection<Cast> _Cast
{
get { return _cast; }
set
{
if (value != _cast)
{
_cast = value;
NotifyPropertyChanged("Cast");
}
}
}
..........
}
Cast.cs
public class Cast
{
public string name { get; set; }
public string imagesource { get; set; }
public Cast(string _name, string _imagesource)
{
this.imagesource = _imagesource;
this.name = _name;
}
}
for each movie i have a list of cast objects
电影模型.cs
App.Model.MovieItems.Add(
new ItemViewModel()
{
_Title = data["title"].ToString(),
_Cast=casObs,
........
}
);
