About
The ComponentOne DataCollection library includes a series of cross-platform observable collections with features like sorting, grouping and filtering and data virtualization techniques like cursor and pagination.
Commonly Used Types:
- C1.DataCollection.C1DataCollection
- C1.DataCollection.C1VirtualDataCollection
- C1.DataCollection.C1CursorDataCollection
- C1.DataCollection.C1PagedDataCollection
In-memory Data Collections
C1DataCollection is the main class used to sort, filter and group any in memory collection like lists, arrays or observable collection
var collection = new ObservableCollection<Item>();
var dc = new C1DataCollection<Item>(collection);
await dc.SortAsync("Property1", "Property2");
All the data-collections implement INotifyCollectionChanged, when a change happens in the underlying ObservableCollection, the change will be reflected and notified immediatly in the data-collection.
Similarly, the C1DataCollection can be grouped and filtered
var collection = new ObservableCollection<Item>();
var dc = new C1DataCollection<Item>(collection);
await dc.GroupAsync("Property1");
var collection = new ObservableCollection<Item>();
var dc = new C1DataCollection<Item>(collection);
await dc.FilterAsync("Property1", FilterOperation.Contains, "X");
Virtualizing Data Collections
C1VirtualDataCollection and C1CursorDataCollection are two abstract collection that can be used to implement collection whose items are pulled on demand from an external source, typically a network call.
