You can use CompositeCollection and CollectionViewSource together.. use CompositeCollection to combine all collections and later create a collection view source from that CompositeCollection. 您可以一起使用CompositeCollection和CollectionViewSource。使用CompositeCollection组合所有集合，然后从该CompositeCollection创建集合视图源。 You can use filter properties in CollectionViewSource 您可以在CollectionViewSource中使用过滤器属性
