Windows phone 7 ObservableCollection仅更新地图缩放和移动事件,不添加到集合中!_Windows Phone 7_Observablecollection - Fatal编程技术网

Windows phone 7 ObservableCollection仅更新地图缩放和移动事件,不添加到集合中!

Windows phone 7 ObservableCollection仅更新地图缩放和移动事件,不添加到集合中!,windows-phone-7,observablecollection,Windows Phone 7,Observablecollection,我对绑定的集合有问题。我有一个手动刷新按钮,可以从服务器上拉出一些移动的图钉。服务器正在自行移动PIN。处理后,我删除现有集合并将其重新添加到可观察集合中。这段代码是有效的,我已经验证了内容已经更新,但是如果地图发生缩放或移动,引脚只会“更新”(在地图上移动) 我的课程如下 public class MapData : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyCha

我对绑定的集合有问题。我有一个手动刷新按钮,可以从服务器上拉出一些移动的图钉。服务器正在自行移动PIN。处理后,我删除现有集合并将其重新添加到可观察集合中。这段代码是有效的,我已经验证了内容已经更新,但是如果地图发生缩放或移动,引脚只会“更新”(在地图上移动)
