如果您正在使用MVVM那么。



1.使用I notifyPropertyvchanged界面在每个类上使用observablecollection< model>

2.绑定您的集合，以添加和更新模型。 />
3.每次在集合中添加项目时，它都会更新UI。

If you are using MVVM then.

1. Bind your collection with the observablecollection <model>
2. on the each class using the I notifyPropertyvchanged interface to add and update the model.
3. Every Time you add a item into the collection it will update the UI.
