Remarks

Server mode allows a data-aware control to work rapidly with large datasets. Loading records in small portions on demand, and performing data-aware operations on the data server side are the key features of server mode. When the control needs to display a specific portion of data, it calls a certain method of the bound server mode data source. This method sends a corresponding request to the data store, and upon receiving the results, passes them back to the control.

The EntityServerModeDataSource component implements the IListSource interface, and can be used as a datasource for a server-mode enabled control (e.g. DXGrid). Use EntityServerModeDataSource to bind a server-mode enabled control to Entity Framework model classes at design time.

Note

The EntityServerModeDataSource is a read-only data source.
