Public Custom Event ContextCreated As EventHandler(Of EntityDataSourceContextCreatedEventArgs)
Handle this event to access the ObjectContext that is used by the EntityDataSource control to execute the query and track changes. This context object can be stored and used for successive operations outside the EntityDataSource. The ObjectContext is obtained from the EntityDataSourceContextCreatedEventArgs that is returned by the ContextCreated event. For more information, see Object Context Life-Cycle Management (EntityDataSource). For more information about the object context, see Identity Resolution, State Management, and Change Tracking.
The ContextCreated event allows you to assign the ObjectContext that has been created to a variable for successive operations outside the EntityDataSource. The EntityDataSourceContextCreatedEventArgs.Context property contains the context that has been created in the ContextCreating event. If the user does not assign a context during the ContextCreating event, the context instance contained in EntityDataSourceContextCreatedEventArgs.Context is the one created by the EntityDataSource based on the EntityDataSource.ContextTypeName, EntityDataSource.DefaultContainerName, or EntityDataSource.ConnectionString properties.
