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.

public class YouTubeCollectionView : C1CursorDataCollection<YouTubeVideo>
    protected override async Task<Tuple<string, IReadOnlyList<YouTubeVideo>>> GetPageAsync(int startingIndex, string pageToken, int? count = null, IReadOnlyList<SortDescription> sortDescriptions = null, FilterExpression filterExpresssion = null, CancellationToken cancellationToken = default(CancellationToken))
        var client = new HttpClient();
        var response = await client.GetAsync(youtubeUrl, cancellationToken);
        var videos = new List<YouTubeVideo>();
        var serializer = new DataContractJsonSerializer(typeof(YouTubeSearchResult));
        var result = serializer.ReadObject(await response.Content.ReadAsStreamAsync()) as YouTubeSearchResult;
        foreach (var item in result.Items)
            videos.Add(new YouTubeVideo(item));
        return new Tuple<string, IReadOnlyList<YouTubeVideo>>(result.NextPageToken, videos);
Composition Data Collections

There are a series of data collections that can be used to compose other collections


Built-in extensions ease the creation of data collections from know sources like EntityFrameworkCore, Ado.Net and BindingList.


Built-in adapters are used to binding data-collections to native controls.


C1.DataCollection.Serialization includes System.Text.Json converters to serialize and deserialize filter, sort and notification classes to Json.
