Remarks
Using the BindToEF method, you can easily bind the CardView to Entity Framework data models. Simply call the method, pass the DataContext and table name as method parameters, and specify the key field via the CardView’s GridSettingsBase.KeyFieldName property.
Internally, the BindToEF method uses our EntityServerModeDataSource component, which was specifically designed to allow the CardView to efficiently process large amounts of data. The EntityServerModeDataSource component automatically enables database server mode to optimize the execution of all queries to the data context initiated by the CardView. In this mode, the CardView loads records on demand and performs data-aware operations (sorting, filtering, etc.) on the data server. This technique significantly improves the CardView’s speed and responsiveness.
Note
The current BindToEF overload catches and conceals any exception thrown by an EF data provider. To catch these exceptions manually, use the BindToEF(string contextTypeName, string tableName, EventHandler<LinqServerModeDataSourceSelectEventArgs> selectingMethod, EventHandler<ServerModeExceptionThrownEventArgs> exceptionThrownMethod) overload method.
