Type Description

A VerticalGridExtension object representing the VerticalGrid extension.


Using the BindToEF method, you can easily bind the VerticalGrid 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 VerticalGrid’s GridSettingsBase.KeyFieldName property.

Internally, the BindToEF method uses our EntityServerModeDataSource component, which was specifically designed to allow the VerticalGrid 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 VerticalGrid. In this mode, the VerticalGrid loads records on demand and performs data-aware operations (sorting, filtering, grouping, etc.) on the data server. This technique significantly improves the VerticalGrid’s speed and responsiveness.


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.
