Remarks

Using the BindToLINQ method, you can easily bind CardView to queryable data sources. 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 BindToLINQ method uses our LinqServerModeDataSource component, which was specifically designed to allow the CardView to efficiently process large amounts of data. The LinqServerModeDataSource component automatically enables database server mode to optimize the execution of all LINQ queries 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 BindToLINQ overload catches and conceals any exception thrown by an IQueryable provider. To catch these exceptions manually, use the BindToLINQ(string contextTypeName, string tableName, EventHandler<LinqServerModeDataSourceSelectEventArgs> selectingMethod, EventHandler<ServerModeExceptionThrownEventArgs> exceptionThrownMethod) overload method.
