    I need lazyloading filterable, groupable, sortable grid. Feature is that set of data constantly grows. Another feature is that datasource is wcf service. Can virtualqueryablecollectionview with gridview help in this scenario?
    I will be grateful if you put a simple example

    Hi,

    The VirtualQueryableCollectionView does not fully support the features you require. For more information, please check our online documentation: Data Virtualization.

    Hi,

    This collection was designed to mostly serve ReadOnly scenarios and its capabilities are limited.

    Grouping is only possible locally on the client. 
    Filtering on Distinct Values is not fully supported when using the VirtualQueryableCollectionView. We suggest configuring GridViewDataColumn withShowDistinctFilters="False". That way only filtering through the Field Filters will be enabled.
    Selection with VirtualQueryableCollectionView is only supported when the selected items are in the View area. It is not possible to select items outside it as the item to be selected is still not presented.

    I hope this helps.
