RadCardView supports sorting via the UI or in code, in case you are using ICollectionView as the ItemsSource.

The control internally works with a QueryableCollectionView instance. If you set the ItemsSource of the RadCardView that is not a QueryableCollectionView, then the original collection is wrapped in a QueryableCollectionView instance. This way sorting is supported even if you use a more basic IEnumerable implementation, like List<T> or ObservableCollection<T>.

Sorting in the UI

The data items can be sorted by clicking on a data field descriptor from the data field descriptors list.

To disable user sorting, set the CanUserSortDescriptors property to False.

Example 1: Setting the CanUserSortDescriptors property

<telerik:RadCardView CanUserSortDescriptors="False" /> 
Additionally, the sorting can be disabled per CardDataFieldDescriptor by setting its AllowSorting property.

Programmatic Sorting

The following example shows how to setup RadCardView, populate it with a QueryableCollectionView and add SortDescriptors in code.

Example 2: Defining the model

public class CardInfo 
    public string Header { get; set; } 
    public string Name { get; set; } 
    public int Number { get; set; } 
    public string Category { get; set; } 
public class MainViewModel 
    public ObservableCollection<CardInfo> Items { get; private set; } 
    public QueryableCollectionView CollectionView { get; private set; } 
    public MainViewModel() 
        int counter = 0; 
        Items = new ObservableCollection<CardInfo>(); 
        for (int g = 0; g < 3; g++) 
            for (int i = 0; i < 6; i++) 
                Items.Add(new CardInfo() 
                    Header = "Card " + counter, 
                    Name = "Name " + counter, 
                    Number = counter, 
                    Category = "Category " + g 
        CollectionView = new QueryableCollectionView(Items); 
        CollectionView.SortDescriptors.Add(new SortDescriptor() { Member = "Name", SortDirection = ListSortDirection.Descending });         

Read the QueryableCollectionView to see how to use the SortDescriptors collection of the QueryableCollectionView.

Example 3: Setting the DataContext

public MainWindow() 
    this.DataContext = new MainViewModel(); 

Example 4: Setting up the view

<telerik:RadCardView ItemsSource="{Binding CollectionView}" CardHeaderBinding="{Binding Header}" /> 


The sorting operations invoke several events that can be used to customize the sort. Read more in the Events article.
