The entire record set required for the current List View is loaded into memory. All the data processing takes place on the client side.

DataView

A lightweight read-only list of data records (EFDataView 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).

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.

Remarks

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

Detailed descriptions of the available data access modes are provided in the following topics.
