| NewItemCreated | Raised after the CreatingNewItem and InitializingNewItem events to signal that a new item has been created. (Inherited from DataGridVirtualizingCollectionViewBase) |
| QueryGroups | Raised to allow the data items contained in a virtualized collection view to be grouped using the information provided by the QueryGroupsEventsArgs received in the event parameters. |
| QueryItemCount | Raised every time the grid is loaded or refreshed or its state changes (e.g., new sorting or filtering criteria are applied), the total number of records in the underlying data source must be provided, taking into account any filters that are currently applied to the items. This event must be handled. |
| QueryItems | Raised whenever new records are required, allowing the next batch of records to be fetched from the data source and provided to the grid. This event must be handled. |
