Name	Description
`Client`	The entire record set required for the current List View is loaded into memory. All the data processing takes place on the client side.
`Server`	Data is requested from a data store in small portions that should currently be displayed. All data-aware operations are performed on the data server side.
`DataView`	A lightweight read-only list of data records (`DevExpress.ExpressApp.EFCore.EFCoreDataView` or XPView) is retrieved without loading complete persistent objects.
`InstantFeedback`	A List View’s control continues responding to a user’s actions while the data is being retrieved in a background thread (see Instant Feedback Mode).
`InstantFeedbackView`	A lightweight read-only list of data records (ObjectRecord) is retrieved without loading complete persistent objects. A List View’s control continues responding to a user’s actions while the data is being retrieved in a background thread.
`ServerView`	A lightweight read-only list of data records (ObjectRecord) is retrieved without loading complete persistent objects. Data is requested from a data store in small portions that should currently be displayed.
`Queryable`	The collection source constructs a query that the List Editor can modify to load only objects visible in the control. Only `DevExpress.ExpressApp.Blazor.Editors.Grid.GridListEditor` [deprecated] supports this mode.
