关于如何对CompositeCollection进行排序的任何想法? [英] Any idea on how to sort a CompositeCollection?

问题描述

我有一个CompositeCollection，它由两种类型的ObservableCollections组成:Company和Contacts. 联系人的属性为FullName，而公司的属性为Name.

我想应用排序，以便集合按其类型混合，但按其名称排序，例如:

Itzhak Perlman
约翰·杜(John Doe)
微软
莎拉·摩尔
StackOverflow
沃尔特·理查森

请注意，我将ItemsControl绑定到CollectionViewSource，其Source设置为CompositeCollection，它的视图变为CompositeCollectionView，它是内部类型，如果我将其类型显式设置为ListCollectionView，则仅包含CollectionContainers作为其项./p>

所需的解决方案是一种解决方法，可以对CompositeCollections进行排序，过滤和分组，我不在乎覆盖并创建自己的CompositeCollection，我只是不知道如何覆盖它并在xaml中启用其功能.

解决方案

谁说我必须利用称为"CompositeCollection"的东西?
我决定不使用CompositeCollection.
我只是创建两种类型混合的ObservableCollection(of Object)，然后将CollectionViewSource绑定到它.

更新

通过继承CompositeCollection并实现 IBindingList ，可以启用排序.

I have a CompositeCollection that consists of ObservableCollections of two types: Companies and Contacts. Contact has a property FullName while Company has a property Name.

I want to apply sorting so the collections are mixed by their types but sorted by their name, example:

Itzhak Perlman
John Doe
Microsoft
Sarah Moore
StackOverflow
Walter Richardson

Note that I bound the ItemsControl to a CollectionViewSource that its Source is set the CompositeCollection, it's view becomes a CompositeCollectionView, it's an internal type, if I explicitly set its type to ListCollectionView, it only contains the CollectionContainers as its items.

Desired solution is a workaround to enable sorting, filtering and grouping on a CompositeCollections, I don't care to override and create my own CompositeCollection, I just don't know how I can override this and enable its functionality in xaml.

解决方案

Who said I must get advantage of the thingy called 'CompositeCollection'?
I decided not to use a CompositeCollection.
I am just creating an ObservableCollection(of Object) mixed of the two types, and binding the CollectionViewSource to it.

Update

By inheriting CompositeCollection and implenting IBindingList, sorting can be enabled.
