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.

Remarks

These enumeration values are used to set the IModelListView.DataAccessMode, IModelOptions.DataAccessMode and CollectionSourceBase.DataAccessMode property.
