Observable Data

Databound components can benefit from live data - when the data source collection changes, the components should update to reflect that change. Most data-bound components in the Telerik UI for Blazor suite implement such functionality.

When the Data of the component is a collection that implements the INotifyCollectionChanged interface (such as ObservableCollection), the Telerik components subscribe to its CollectionChanged event to update. This means that adding items, removing items, or clearing the collection updates the components (its .Add(), .Remove() and .Clear() methods).

The following components support observable data:

  • AutoComplete

  • ComboBox

  • DropDownList

  • Grid

  • ListView

  • MultiSelect

  • TreeList

  • TreeView

The Scheduler, Menu, Drawer, ContextMenu will receive this feature in a future release.
