EntityInstantFeedbackDataSource Class

A non-visual component that can be used as a data source for the GridControl in Instant Feedback UI Mode. Can be associated with an Entity Framework queryable source.

Namespace:DevExpress.Xpf.Core.ServerMode
Assembly:DevExpress.Xpf.Core.v19.2.dll

Expanded Syntax

Expanded Remarks

The EntityInstantFeedbackDataSource is a non-visual component that is available via the Items Source Wizard. It implements the same functionality introduced by DevExpress.Data.Linq.EntityInstantFeedbackSource

Note

The EntityInstantFeedbackDataSource is a read-only data source.

Expanded Example

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.
