Use VirtualQueryableCollectionView for on-demand data loading that provides smooth and seamless scrolling with UI virtual components. The on-demand loading feature comes in handy when users have to work with large amounts of data. It enables the control to download only the necessary screen-display information as opposed to the whole data. Thus, the loading is much faster and the end-user experience is much smoother.
This collection is mainly intended to serve ReadOnly scenarios. When using VirtualQueryableCollectionView for WPF, you can benefit from the built-in selection, sorting and filtering functionalities. However, full support for extended selection and filtering is not provided.
