多个ObservableCollections绑定到一个的ObservableCollection [英] Binding multiple ObservableCollections to One ObservableCollection

问题描述

有一大堆的的ObservableCollection＆LT; MeClass＆GT;结果，并要求将它们全部组合成另一个的ObservableCollection＆LT; MeClass＆GT; AllResults 这样我就可以在列表视图中显示它。

Have a bunch of ObservableCollection<MeClass> Result and require to combine them all into another ObservableCollection<MeClass> AllResults so I can display it in a listview.

只是不知道如何将它们结合起来的。

Just not sure how to combine them all in one.

我创建了一个新的类来他们都结合起来，但不知道他们将如何得到更新后，我得到的名单，一旦...所以真的不知道该走的方向。

I Created a new class to combine them all but not sure how they will get updated after I got the list once... So not really sure which direction to take.

我知道 INotifyPropertyChanged的我只是不知道如何把它们都结合起来，并不断更新的一切都变了。

I know about INotifyPropertyChanged I'm just not sure how to combine them all and keep updating as everything changes.

推荐答案

.NET有一个<一个href="http://msdn.microsoft.com/en-us/library/system.windows.data.compositecollection.aspx"><$c$c>CompositeCollection这可以让你把多个集合作为一个单一的集合。它实现了 INotifyCollectionChanged ，所以只要你的内心集合实施 INotifyCollectionChanged ，以及（在你的情况下，他们当然喜欢） ，您的绑定应该没有任何问题。

.NET has a CompositeCollection that allows you to treat multiple collections as a single collection. It implements INotifyCollectionChanged, so as long as your inner collections implement INotifyCollectionChanged as well (which in your case they certainly do), your bindings should work without any problems.

用例：

CompositeCollection cc = new CompositeCollection();
CollectionContainer container1 = new CollectionContainer() { Collection = Result1 }
CollectionContainer container2 = new CollectionContainer() { Collection = Result2 }
cc.Add(container1);
cc.Add(container2);
