Remarks

Server mode allows a data-aware control to rapidly work 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 specific 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 EntityServerModeSource component implements the IListSource interface, and can be used as a data source for a control supporting the server mode feature.

Use EntityServerModeSource to bind a server-mode enabled control to Entity Framework 4+ model classes. To see an example, refer to the Entity Framework 4.0+ Server Mode help topic.

Note

EntityServerModeSource is a read-only data source.
