Show Me

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=E3160.

This example shows how to implement the Instant Feedback UI Mode (asynchronous data loading) for the grid bound to the Entity Framework 4.0 Classes. To activate this feature, our specially designed data source (DevExpress.Data.Linq.LinqInstantFeedbackSource) is used.
